22,039 Pounds: The World-Record Boerboel Weight Pull & the Cold River Performance Program

On May 9, 2026, Cold River’s Sun Wukong and Cold River’s Mr. Wednesday each successfully pulled 22,039 pounds in sanctioned dog weight-pull competition.
Not in training. Not in a private demonstration. And not from a number estimated by watching a video.
They did it at a sanctioned Unified Pulling Federation event, on rails, under established competition rules, with the performances witnessed publicly and the results officially recorded.
Two dogs. Same event. Same weight. 22,039 POUNDS.
That figure stands as the heaviest documented single-dog weight-pull performance we have identified in comparable sanctioned competition worldwide.
The accomplishment itself is remarkably straightforward. Some of the discussion surrounding it has not been.
So rather than asking anyone to accept a headline, we’re going to break down the event, the record, the judging, the placements, the dogs, the genetics, and the Cold River performance program behind them.
Because a results sheet can tell you what number was recorded. Understanding the sport tells you what that number actually means.
The 22,039-pound performances by Cold River’s Sun Wukong and Cold River’s Mr. Wednesday have generated considerable attention—and, inevitably, considerable discussion.
As information about the accomplishment has spread online, so have incomplete explanations of the event, confusion over terminology, selective interpretations of the results, and commentary from individuals who were not present.
Normally, we would have little interest in responding to every opinion published online. But when commentary begins being presented as factual information about our dogs, our program, our handling decisions, and an event at which we actually competed, we believe the complete record should be available directly from the people who were there.
This page exists for that reason.
Not to create an ongoing argument.
Not to attack anothers.
And not to ask anyone to simply take our word for it.
It exists to put the complete information in one place.
The sanctioned results. The 22,039-pound performances. The judging. The placements. The handler withdrawals. The distinction between Most Weight Pulled and Most Weight Pulled Per Pound. The dogs’ development. The breeding decisions. And the Cold River program responsible for selecting, raising, training, conditioning, and handling them.
Readers can examine the information and reach their own conclusions.
Our responsibility is simply to make sure the complete story is available.
One misconception deserves to be addressed immediately:
A world record and a Guinness World Records title are not synonymous.
Guinness World Records is an independent record-keeping organization that establishes and verifies its own defined record categories. It is not the international governing body over every competitive sport in existence.
Guinness does not determine whether every world record in every sport is a world record. It determines which achievements Guinness World Records itself recognizes and certifies within the record categories it chooses to monitor.
In fact, Guinness's own FAQ acknowledges that when a particular record cannot be found in its database, one possible explanation is that it is simply “not a record that we currently monitor.” Guinness also maintains specific criteria for which record titles it will recognize and explains that certain categories are not monitored or accepted at all.
That distinction matters.
The absence of a Guinness title does not, by itself, establish that a sporting record does not exist. It establishes that the achievement does not hold a Guinness World Records title.
Cold River has never claimed: “Guinness World Record.”
What we hold is a world record in sanctioned dog weight pull: 22,039 pounds, achieved by Cold River's Sun Wukong and Cold River's Mr. Wednesday.
That record was not created by Cold River simply calling it one. As detailed below, the 22,039-pound mark was verified directly with the sanctioning organization.
Those are different things.
Guinness certification would represent recognition within Guinness's own record system. It is not what creates the underlying sporting accomplishment, nor is Guinness certification a universal requirement before an achievement can properly be described as a world record within a sport.
The relevant question is much simpler:
Has a single dog produced a heavier documented performance in comparable sanctioned weight-pull competition?
That is the question that matters here.
And to date, neither our research nor the scrutiny surrounding this accomplishment has identified a heavier comparable sanctioned single-dog performance.
The 22,039-pound record was not something Cold River simply declared for itself.
The performance occurred at a sanctioned Unified Pulling Federation (UPF) event on May 9, 2026, under the organization’s established rules and judging procedures. The event and its results became part of UPF’s official competition record.
But we went one step further.
The record status was verified directly with the president and founding member of the Unified Pulling Federation.
Confirmation was obtained that 22,039 pounds represents the highest weight pulled by a dog within the organization, including its competition history in both the United States and the United Kingdom.
That distinction is important because it removes Cold River from the position of simply declaring its own accomplishment to be a record.
We competed. The dogs pulled the weight. The judges witnessed it. The results were recorded through the sanctioning organization. And the record status was verified directly with the organization itself.
There is also an important piece of context when discussing the larger world-record designation.
Even independent scrutiny of the available published weight-pull records has reached the same fundamental conclusion: 22,039 pounds is the heaviest documented single-dog weight-pull performance identified across the published results of the major weight-pull organizations. In fact, even sources attempting to distinguish between a “documented” record and a “certified” world record acknowledge that no heavier credible single-dog performance has been identified.
So the disagreement is no longer about what happened.
The weight is documented.
The event was sanctioned.
The performance was judged.
The result was recorded.
The organization confirmed the record.
And no heavier comparable sanctioned single-dog performance has been identified.
At that point, the argument is no longer about the number. It is about what someone chooses to call it.
And that brings us directly to the next question.
When Somebody Says, “Why We Still Won’t Call It a World Record”
…in their little voice.
Here is where the distinction between evidence and word choice becomes impossible to ignore.
After examining published weight-pull results across multiple organizations, even those scrutinizing the 22,039-pound performance have acknowledged the central fact:
They have not identified a single dog, anywhere in the available documented record, that has pulled more weight than Cold River’s Sun Wukong and Cold River’s Mr. Wednesday.
Think about what that means.
The performance occurred at a sanctioned event.
The weight is officially recorded.
The sanctioning organization has confirmed the record.
The performances were witnessed by certified judges and competitors in attendance.
Video exists from multiple sources.
The event was also broadcast live through social media.
And after searching historical results from other weight-pull organizations, no heavier credible comparable single-dog performance has been identified.
Yet after establishing all of that, someone can still arrive at:
“We still won’t call it a world record.”
Fine.
Everyone else calls it one.
More importantly, changing the terminology does not change the accomplishment.
Call it a world record.
Call it the heaviest documented sanctioned single-dog weight pull.
Call it the highest verified weight recorded within UPF.
Or spend an entire page explaining why you personally prefer not to use two particular words.
The number remains 22,039 pounds.
And that is ultimately the irony in scrutinizing the claim this closely: the attempt to challenge it has instead produced additional research supporting the underlying accomplishment.
When independent scrutiny intended to question a record ultimately concludes that no heavier documented comparable performance can be identified, the disagreement has stopped being about evidence.
It has become a disagreement about vocabulary.
The dogs already settled the part that matters on the track.
Who Ran the Event — And What Actually Happened
Some commentary surrounding the 22,039-pound performances has focused on who organized, judged, sponsored, or competed at the event—as though that overlap somehow casts doubt on the result.
It does not.
The May 9, 2026 event was a sanctioned Unified Pulling Federation (UPF) weight pull, conducted under the organization’s established competition rules and judging procedures. The event and its results became part of UPF’s official competition record.
The Chief Judge Also Competed — So Let’s Explain What That Actually Means
Erica Noseworthy served as chief judge and also competed with her own dogs that day.
What gets conveniently left out is rather important:
Erica did not judge her own dogs.
When a judge is competing with his or her own dog, another qualified judge performs the judging responsibilities for that dog.
This is also a practical necessity. A handler cannot be on the track handling a dog while simultaneously performing the judging and timing responsibilities required for that same performance.
A judge competing at an event is therefore not evidence of some irregularity. Experienced competitors frequently serve as judges within weight pull, and qualified judges can also compete.
More importantly, Erica was certainly not the only qualified judge standing there.
There were six certified/qualified judges present at the event in total: Erica Noseworthy, Emmanuel Hunter, Eli Carver, Ron Smith, Todd Thurber, and Alisha Graham. All six also competed that day and witnessed the event.
These were not six random spectators unfamiliar with weight pull. They were individuals qualified to understand the rules, the track, the judging procedures, the loading of the cart, and exactly what constituted a successful pull.
That does not weaken the validation of what occurred—it strengthens it.
The 22,039-pound performances did not happen in isolation. They happened in front of an unusually concentrated group of experienced weight-pull competitors and qualified judges who were physically present and able to see the performances for themselves.
What About Eli Carver Being a UPF Judge?
Yes. Eli Carver is a UPF judge.
He was also the owner and handler of Cold River’s Sun Wukong and Cold River’s Mr. Wednesday.
But listing that fact without explaining his actual role at this particular event creates an implication that simply is not accurate.
Eli Carver did not organize the event. He did not run the event. And he did not judge his own dogs.
He attended the event as a competitor and handler, just as other certified/qualified judges in attendance also competed with their own dogs.
Being qualified as a judge does not somehow prevent a person from competing. In fact, experience within the sport is precisely what gives a qualified judge the knowledge necessary to understand and officiate it.
Without context, simply writing “the owner of the dogs is also a UPF judge” can be made to sound suspicious.
With the context included, it describes something considerably less dramatic:
An experienced weight-pull competitor who is qualified to judge weight-pull events competed with his own dogs while other qualified judges officiated the competition.
And again, there were six certified/qualified judges present in total.
What About Bully Max?
Yes. Bully Max sponsored and hosted the event at its facility.
That is not hidden, controversial, or evidence against the performance.
Sponsors and hosts are part of organized sporting events. Their involvement does not determine whether a dog successfully completed a pull.
And this was hardly an undocumented private demonstration occurring behind closed doors.
The event was public and extensively documented.
Multiple people recorded video.
Bully Max recorded video.
Spectators and competitors recorded video.
The event was also broadcast live through social media, allowing thousands of people who were not physically present to watch what was happening as it occurred.
Most importantly, however, the record does not depend upon a promotional video from Bully Max.
It depends upon what happened on the track and what was recorded through the sanctioned competition.
The dogs pulled the weight.
The judges witnessed the performances.
The weight was loaded in front of those present.
The results were recorded.
The event became part of UPF’s official competition record.
And, as already explained, the record status was subsequently verified directly with the organization.
Context Changes Everything
There is a larger lesson here.
A person unfamiliar with competitive weight pull can collect isolated facts from the internet—
the chief judge also competed…
the owner of the record-holding dogs is himself a judge…
the sponsor hosted the event…
—and arrange those facts in a way that makes ordinary aspects of a weight-pull event sound unusual.
But isolated facts are not the same thing as understanding how the sport actually operates.
And that distinction becomes especially important when commentary about an event is coming from someone who was not there, did not compete, did not judge, and is attempting to reconstruct what happened afterward from information found online.
The people who actually were there saw something considerably less mysterious.
Six certified/qualified judges were present: Erica Noseworthy, Emmanuel Hunter, Eli Carver, Ron Smith, Todd Thurber, and Alisha Graham. All six competed and witnessed the event. Competitors and spectators witnessed the performances. Multiple recordings exist. The event was broadcast live. The results were recorded through the sanctioning organization. And the 22,039-pound performances became part of UPF’s official competition record.
None of those facts diminish the accomplishment.
They document it.
Understanding the Placements: First Place Was Never the Whole Story
One of the easiest ways to misunderstand a weight-pull event is to look at a results sheet without understanding how the competitors actually approached the competition.
On paper, someone may see that Cold River’s Conquest placed first, while Cold River’s Sun Wukong and Cold River’s Mr. Wednesday finished third and fourth in their class, and assume those placements somehow diminish what Sun Wukong and Mr. Wednesday accomplished.
They do not.
And anyone who was actually present and understood what was happening on the track would know why.
There is an important distinction between winning a class and pursuing Most Weight Pulled Overall.
In the Unlimited class, many experienced competitors are not necessarily chasing first place within the class. They are pursuing the coveted Most Weight Pulled Overall award—the greatest actual amount of weight successfully moved at the event.
That was our objective.
We were not interested in unnecessarily competing against our own dogs simply to rearrange first, second, third, and fourth place on a results sheet.
And there is another critical fact that a placement alone does not show:
Our dogs were not worked to failure.
Cold River’s Conquest — First Place, First Event
Cold River’s Conquest took first place.
What a results sheet does not tell you is that Conquest was handler withdrawn.
We did not continue adding weight until she failed.
Once we were satisfied with what she had accomplished, we stopped her ourselves.
That distinction matters even more considering something else:
This was Conquest’s first weight-pull event.
She entered an event of this magnitude for the first time, performed successfully, took first place, and was withdrawn by her handler rather than being pushed until she could no longer complete a pull.
That is not something we need to explain away.
That is an accomplishment in its own right.
Cold River’s ALUCARD — Another First-Time Competitor
The same broader context applies to Cold River’s ALUCARD.
ALUCARD is also a female, and this was also her first weight-pull event.
Like Conquest, she was stepping onto the track in actual sanctioned competition for the first time—and doing so at an event of considerable scale.
For us, developing dogs correctly has always mattered more than squeezing one additional placement or one additional pull out of a dog simply because we can.
Sun Wukong and Mr. Wednesday — The Objective Was 22,039 Pounds
With Cold River’s Sun Wukong and Cold River’s Mr. Wednesday, the objective was different.
We were pursuing Most Weight Pulled Overall and the record.
Both dogs successfully moved:
22,039 POUNDS.
Once that objective had been accomplished, we stopped.
They were not continued simply to chase a different class placement.
They were not repeatedly loaded until they eventually failed.
They had already accomplished what we brought them there to accomplish.
They were handler withdrawn.
That is an enormously important distinction when interpreting third- and fourth-place finishes.
A placement tells you where a dog appears in a particular competitive category.
It does not necessarily tell you where that dog’s physical limit was.
Sun Wukong and Mr. Wednesday’s limit was never established that day because we chose not to find it.
Why Compete Against Our Own Dogs?
There is also a practical question:
Why would we?
Cold River already had a dog sitting in first place with Cold River’s Conquest.
Our objective with Sun Wukong and Mr. Wednesday was not to knock one Cold River dog out of position so another Cold River dog could move up a line on the results sheet.
The larger objective was sitting on the track in front of us:
Most Weight Pulled Overall.
22,039 pounds.
The record.
Once the dogs accomplished that objective, our job as handlers was finished.
Knowing when to stop a dog is every bit as much a part of handling as knowing when to ask a dog for another pull.
A Results Sheet Records the Outcome. It Does Not Tell the Entire Story.
This is precisely why discussing an event you did not attend—and a sport you have never participated in—can lead to misleading conclusions.
A results sheet can tell you:
1st.
2nd.
3rd.
4th.
What it cannot necessarily tell you is:
which dogs were worked to failure;
which dogs were handler withdrawn;
what objectives individual handlers were pursuing;
why a handler elected to stop;
or what was actually occurring strategically on the track.
That context comes from understanding the sport and being there.
Cold River’s Conquest took first place.
Cold River’s ALUCARD successfully competed in her first event.
Cold River’s Sun Wukong and Cold River’s Mr. Wednesday each pulled 22,039 pounds.
And when we had accomplished what we came to accomplish, we put the dogs away.
The placement never diminished the record.
The handler withdrawals actually tell you something the placement cannot:
22,039 pounds is where we stopped.
It is not where the dogs proved they had to stop.
Producing an Ancestor Is Not the Same as Producing a Performance Program
There is another part of this story that deserves clarification because pedigree and performance development are not the same thing.
Cold River’s Sun Wukong and Cold River’s Mr. Wednesday did not appear by accident.
Nor were they simply the inevitable result of having a particular dog somewhere in their pedigree.
Their sire contributed genetically to the breeding. That is a fact, and we have never disputed it.
But genetics do not work through attribution alone.
A sire contributes approximately half of the genetic material to a litter. The dam contributes the other half. What ultimately emerges from those genetics—and which individuals are selected, retained, developed, trained, conditioned, tested and eventually bred forward—is where a breeding program begins to reveal itself.
And that distinction is particularly important here.
This Was Not an Established Weight-Pull Bloodline
Neither side of the breeding that produced Sun Wukong and Mr. Wednesday came from an established weight-pull family.
Their sire had no competitive weight-pull history.
Their dam came from a very well-established, multi-generational line—but that line had no established weight-pull history.
The generations immediately behind them were not established weight-pull dogs either.
There was no existing Boerboel weight-pull blueprint for us to simply follow.
We were attempting to build one.
The breeding itself was selected by Cold River as part of a larger idea: identify physical and genetic characteristics we believed could produce the type of Boerboel we wanted, make the breeding, evaluate what it produced, and then select the individuals that best represented the direction of the program.
The sire possessed a certain characteristic we liked—mainly height
The dam brought her own genetic contribution and came from a more established multi-generational family.
But neither dog arrived with a résumé proving that their offspring would become elite weight-pull dogs.
That had to be discovered.
Fourteen Puppies. Seven Retained. Two Ultimately Selected.
This is perhaps one of the most important pieces of the development story.
The breeding produced 14 puppies.
Cold River initially retained seven of them.
Why keep half of an entire litter?
Because we were entering relatively uncharted territory with the Boerboel.
We were not working with generations of established weight-pull dogs where previous performance gave us a predictable roadmap.
We needed to watch them develop.
Structure.
Movement.
Drive.
Temperament.
Athletic ability.
Physical development.
Work ethic.
Recovery.
Mental resilience.
And the countless smaller characteristics that experienced dog people learn to recognize after decades of working with performance animals.
As those puppies developed, the seven were gradually evaluated and narrowed down.
Ultimately, two remained as the primary selections from that group:
Cold River’s Sun Wukong.
Cold River’s Mr. Wednesday.
Those selections were made long before anyone knew that both dogs would eventually stand on the same track and pull 22,039 pounds each.
That is where experience matters.
Nearly Five Decades of Combined Experience Went Into Those Decisions
Cold River is built around a husband-and-wife team with decades of hands-on experience working with performance dogs—one with 27 years of experience and the other with 19 years.
Together, that represents nearly 50 years of combined experience—almost five decades—in breeding, raising, training, conditioning, evaluating, and developing working dogs.
That experience became especially important because this was not our first time attempting to develop performance dogs from genetics that did not already carry an established weight-pull résumé.
Cold River has done it before.
Long before Sun Wukong and Mr. Wednesday, we had taken dogs from another breed and from genetics with no established weight-pull background, selectively developed that family for performance, and worked with that line successfully for more than 15 years.
And long before these two Boerboels stepped onto the track, Cold River had already produced record-breaking weight-pull dogs.
So when we began developing a performance direction within the Boerboel, we were not attempting to learn the fundamentals of performance breeding as we went.
We were applying decades of previous experience to a new breed and a new genetic puzzle.
There is an enormous difference.
Then the Next Generation Started Answering the Question
One exceptional dog can happen.
Even two exceptional littermates can cause someone to ask whether the result was simply an extraordinary combination of genetics.
That is why what happened after Sun Wukong and Mr. Wednesday matters.
Cold River’s Conquest is a daughter of Cold River’s Mr. Wednesday.
She stepped into her first weight-pull event, performed successfully, and took first place before being handler withdrawn.
Then there is Cold River’s ALUCARD.
ALUCARD is the maternal half-sister of Sun Wukong and Mr. Wednesday—produced from their mother bred to a different male.
She also successfully entered competition at her first event.
Now the picture becomes considerably more interesting.
Different generations.
Different paternal combinations.
The same developing Cold River performance direction.
That does not mean every puppy carrying these genetics will become an elite performance dog. No responsible breeder can make that claim.
What it does provide is additional performance information that can be used to make the next generation of breeding decisions.
And that is exactly how a working line is built.
Bloodlines Give You Possibilities. Selection Builds a Program.
Every dog has a sire.
Every dog has a dam.
Every breeder working with dogs today is building upon genetics that existed before them.
Giving proper credit to ancestry is important.
But ancestry and accomplishment should not be confused.
The breeder of an ancestor did not select which seven puppies Cold River retained.
They did not spend months evaluating those seven.
They did not narrow those selections.
They did not raise Sun Wukong and Mr. Wednesday.
They did not develop their conditioning programs.
They did not train them for weight pull.
They did not determine their competition strategy.
They did not stand behind them on the track.
And they did not make the handling decisions that ultimately resulted in two dogs successfully pulling 22,039 pounds apiece.
Cold River did.
The ancestry is part of their pedigree.
The performance program is Cold River.
And perhaps the clearest evidence of what we are building will not ultimately be Sun Wukong or Mr. Wednesday themselves.
It will be what comes after them.
Because a performance line is not established by repeatedly pointing backward at an ancestor.
It is established by producing forward.
I especially like that final sequence for this page:
“The ancestry is part of their pedigree. The performance program is Cold River.”
Then:
“A performance line is not established by repeatedly pointing backward at an ancestor. It is established by producing forward.”
When Performance Starts Repeating, Pay Attention
One exceptional performance can get your attention.
Two littermate brothers producing exceptional performances certainly gets your attention.
But for a breeder developing a working line, the bigger question is always:
What happens next?
Can the characteristics you selected for begin appearing again?
Can performance move into the next generation?
Can related dogs from different breeding combinations demonstrate similar working ability?
Because that is where an interesting individual performance begins becoming something much more important:
A pattern.
And that is exactly what we are beginning to see at Cold River.
Cold River’s Conquest — Performance Into the Next Generation
Cold River’s Conquest is a daughter of Cold River’s Mr. Wednesday.
That makes her particularly important to us—not simply because of what she accomplished at the May 9 event, but because she represents the next generation of the developing Cold River performance family.
At her very first weight-pull event, Conquest stepped onto the track, performed successfully, took first place, and was ultimately handler withdrawn rather than worked until failure.
Think about the progression:
Mr. Wednesday proves himself in competition.
Then one of his daughters enters competition.
And she performs.
That does not prove that every offspring of Mr. Wednesday will become a high-level performance dog. Genetics do not work that way, and responsible breeding programs do not make those kinds of guarantees.
But it gives us something extremely valuable:
Information.
It tells us that some of the characteristics we selected for may be transmitting forward.
And that gives us another piece of information for deciding what comes next.
Cold River’s ALUCARD — Same Maternal Family, Different Sire
Then there is Cold River’s ALUCARD.
ALLUCARD gives us a different piece of the puzzle.
She is the maternal half-sister of Cold River’s Sun Wukong and Cold River’s Mr. Wednesday.
Same maternal family.
Different sire.
And at her first weight-pull event, she also stepped onto the track and successfully performed.
That distinction matters.
Sun Wukong and Mr. Wednesday came from one particular sire-and-dam combination.
ALUCARD came through the same well-established maternal line but from a different sire.
And yet we are again seeing performance.
Does that allow us to assign some imaginary percentage of credit to one ancestor or another?
Of course not.
Genetics are considerably more complicated than that.
But it does demonstrate why attempting to explain the accomplishments of an entire developing performance family by repeatedly pointing to one sire is far too simplistic.
We are now looking at performance appearing through:
Cold River’s Sun Wukong.
Cold River’s Mr. Wednesday.
Mr. Wednesday’s daughter, Cold River’s Conquest.
And their maternal half-sister, Cold River’s ALUCARD, from a different sire.
That is precisely the type of information a breeder watches when trying to determine whether a program is moving in the intended direction.
This Is What Building a Line Looks Like
A line is not created by a website description.
It is not established because a pedigree contains a particular name.
And it certainly is not established by one impressive dog.
A line is built through selection, testing, evaluation, reproduction, and then testing again.
Generation after generation.
You make a breeding based upon what you believe the genetics may produce.
You retain prospects.
You evaluate them.
You select.
You develop them.
Then you test your theory.
The dogs either give you the answer you wanted—or they teach you something that changes the next decision.
Then you breed forward and ask the question again.
That process takes years.
Sometimes decades.
And there are no shortcuts.
The Track Is Where the Theory Gets Tested
This is why competition matters so much to us.
Pedigrees tell us where a dog came from.
Breeding decisions tell us what we hope to produce.
Training and conditioning tell us what we can develop.
But eventually:
The dog has to perform.
Cold River’s Sun Wukong performed.
Cold River’s Mr. Wednesday performed.
Cold River’s Conquest performed.
Cold River’s ALUCARD performed.
Different relationships.
Different generations.
Different breeding combinations.
Same developing performance program.
We are not declaring the work finished.
Quite the opposite.
We believe we are watching the beginning of it.
The Cold River performance line is still being written, and we intend to continue doing exactly what brought us this far:
Breed with purpose.
Select with experience.
Develop with patience.
Condition with intention.
And test it on the track.
Because ultimately, a pedigree tells you what went into the dog.
Performance tells you what came out.
A Pedigree Explains Ancestry. Performance Establishes the Program.
Pedigrees matter.
Genetics matter.
The dogs appearing behind an accomplished animal are part of its genetic history.
That is a simple pedigree fact.
But a pedigree and a performance program are not the same thing.
A pedigree documents where the genetics came from.
It does not tell you who planned a particular breeding.
It does not tell you who evaluated the litter.
It does not tell you which prospects were retained.
It does not tell you who spent months or years developing those prospects.
It does not tell you who trained them.
It does not tell you who conditioned them.
It does not tell you who prepared them for competition.
But in this case, we can tell you exactly who did.
COLD RIVER DID.
Through the Cold River performance program, these dogs were purposefully bred, selected, evaluated, raised, developed, trained, conditioned, prepared, and ultimately proven in sanctioned competition.
And that distinction matters.
A pedigree can document what went into a dog.
A performance program demonstrates what was done with that potential.
And ultimately, the dog still has to answer the final question on the track.
For Cold River’s Sun Wukong and Cold River’s Mr. Wednesday, that answer was:
22,039 POUNDS.
A NEW WORLD RECORD IN SANCTIONED DOG WEIGHT PULL.
Breeders can plan.
Trainers can prepare.
Conditioners can develop.
Handlers can guide.
But ultimately, the dogs still have to perform.
And credit Cold River’s Sun Wukong and Cold River’s Mr. Wednesday for doing what no dog before them had done:
SETTING A NEW WORLD RECORD — 22,039 POUNDS.
Cold River could prepare them for the opportunity.
Cold River could put them on the track.
But the dogs had to move the cart.
And they did.
Cold River’s Sun Wukong — 22,039 pounds.
Cold River’s Mr. Wednesday — 22,039 pounds.
Two Cold River Boerboels.
One new world-record mark.
Achieved twice.
22,039 Pounds — What Actually Happened
Why We Published This Page
First Things First: World Record Does Not Mean Guinness World Record.
The Record Was Verified With UPF
Claim vs. Context: What the Full Record Actually Shows
Throughout the discussion surrounding the 22,039-pound world record, individual facts have sometimes been presented without the context necessary to understand what actually happened.
So rather than continue discussing interpretations, here are the major points in their simplest form.
CLAIM: “It Isn’t a World Record Because It Isn’t Guinness Certified.”
Missing Context: Guinness World Records does not govern every sport or monitor every possible record category. Guinness itself acknowledges that some records are simply not records it currently monitors.
The Full Record: Cold River has never claimed a Guinness World Record. Cold River’s Sun Wukong and Cold River’s Mr. Wednesday hold the 22,039-pound world record in sanctioned dog weight pull. The record was verified directly with the sanctioning organization, and no heavier comparable sanctioned single-dog performance has been identified.
CLAIM: “The Chief Judge Also Competed.”
Missing Context: A judge competing with her own dog does not mean she judged her own dog. Another qualified judge performs the necessary judging responsibilities while that person competes.
The Full Record: There were six certified/qualified weight-pull judges present at the event: Erica Noseworthy, Emmanuel Hunter, Eli Carver, Ron Smith, Todd Thurber, and Alisha Graham. All six also competed and witnessed the event.
Six qualified judges being present does not weaken the documentation of the performances. It strengthens it.
CLAIM: “The Owner of the Record-Holding Dogs Is Also a Judge.”
Missing Context: Being qualified to judge weight pull does not mean someone officiates every event they attend—or judges their own dogs.
The Full Record: Eli Carver attended and competed as the owner and handler of Cold River’s Sun Wukong and Cold River’s Mr. Wednesday. He did not run the event and did not judge his own dogs.
CLAIM: “Bully Max Sponsored and Hosted the Event.”
Missing Context: Sponsoring or hosting a sanctioned sporting event does not create the competitive results.
The Full Record: Bully Max sponsored and hosted the event, but the performances occurred in sanctioned competition. Multiple competitors and spectators witnessed and recorded the event, qualified judges were present, the event was broadcast live, and the results became part of the sanctioning organization’s competition record.
The cameras documented 22,039 pounds. They did not create it.
CLAIM: “Sun Wukong Finished Third and Mr. Wednesday Finished Fourth.”
Missing Context: Placement and Most Weight Pulled Overall are not the same measurement of accomplishment.
Cold River’s objective with Sun Wukong and Mr. Wednesday was the greatest absolute weight successfully moved.
The Full Record: Both dogs successfully pulled 22,039 pounds and were then handler withdrawn.
They were not continued until failure simply to rearrange class placements.
CLAIM: “Conquest Finished Ahead of the Record Holders.”
Correct.
And we're proud of her.
Cold River’s Conquest took first place at her very first weight-pull event.
She was also handler withdrawn rather than worked until failure.
That doesn't diminish the accomplishments of Sun Wukong and Mr. Wednesday.
It demonstrates the depth of the Cold River performance program.
CLAIM: “22,039 Pounds Was Their Maximum.”
That has never been established.
The Full Record: 22,039 pounds was the final successful pull for Cold River’s Sun Wukong and Cold River’s Mr. Wednesday before they were handler withdrawn.
Neither dog was subsequently worked to failure.
We will not invent a hypothetical number and claim they could have pulled 23,000, 24,000, 25,000 pounds—or anything else.
We don't know.
What we do know is considerably more important:
They successfully pulled 22,039 pounds.
That is where Cold River stopped them.
It is not where the dogs proved they had to stop.
CLAIM: “Their Pedigree Explains the Accomplishment.”
Missing Context: Pedigree explains ancestry. It does not document selection, development, training, conditioning, competition preparation, or handling.
The Full Record: The breeding was planned by Cold River. The prospects were retained and evaluated by Cold River. Sun Wukong and Mr. Wednesday were selected by Cold River. They were raised, developed, trained, conditioned, prepared, and handled through the Cold River performance program.
And ultimately:
The dogs themselves still had to perform.
They did.
Strip Away Every Argument and the Same Facts Remain
Remove the commentary.
Remove the selective interpretations.
Remove the arguments over terminology.
Remove the opinions of people who were not on the track.
What remains?
A sanctioned weight-pull event.
Six qualified judges present.
Official competition results.
A record verified directly with the sanctioning organization.
No heavier comparable sanctioned single-dog performance identified.
Cold River’s Sun Wukong — 22,039 pounds.
Cold River’s Mr. Wednesday — 22,039 pounds.
TWO COLD RIVER BOERBOELS.
ONE WORLD-RECORD MARK.
ACHIEVED TWICE.
CLAIM: “The Four Highest Documented Boerboel Weight-Pull Performances Came From This Event.”
That is correct.
And this is one point where no rebuttal is necessary.
The numbers speak for themselves.
The four performances were:
Cold River’s Sun Wukong — 22,039 pounds
Cold River’s Mr. Wednesday — 22,039 pounds
Cold River’s Conquest — 21,336 pounds
Cold River’s ALUCARD — 17,076 pounds
But there is an important piece of context that should accompany those numbers:
ALL FOUR DOGS WERE PRODUCED, OWNED, RAISED, TRAINED, CONDITIONED, AND HANDLED BY COLD RIVER BOERBOELS.
These were not four unrelated Boerboels from four different breeders or four different performance programs that happened to produce exceptional numbers at the same event.
They were four Cold River Boerboels from the same developing Cold River performance program.
The two highest performances belonged to Cold River’s Sun Wukong and Cold River’s Mr. Wednesday, with each dog successfully pulling the new world-record mark of 22,039 pounds.
Then came Cold River’s Conquest at 21,336 pounds—at her first weight-pull event.
And Cold River’s ALUCARD at 17,076 pounds—also at her first weight-pull event.
So when discussing how strong a Boerboel can be, these four performances provide an extraordinary answer.
But they also answer another question:
What performance program produced the dogs responsible for those four performances?
COLD RIVER BOERBOELS.
Four dogs.
Four of the highest documented Boerboel weight-pull performances identified in the available published record.
Two first-time competitors.
Two dogs reaching 22,039 pounds.
One program behind all four.
COLD RIVER BOERBOELS.
That is not simply evidence of what the Boerboel breed is capable of.
It is documented evidence of what the Cold River Boerboels performance program has produced.
And that distinction belongs in the record too.
The Bottom Line: Records Are Established on the Track
At some point, every discussion has to return to the actual evidence.
Not opinions.
Not selective interpretations.
Not semantics.
Not who can write the longest explanation after the event.
The track.
That is where performance is measured.
That is where the dogs are tested.
And that is where Cold River Boerboels chooses to answer questions about its performance program.
On May 9, 2026, the results were straightforward:
Cold River’s Sun Wukong — 22,039 pounds.
Cold River’s Mr. Wednesday — 22,039 pounds.
Two Cold River Boerboels successfully reached the same world-record mark in sanctioned dog weight pull.
They did it publicly.
They did it in sanctioned competition.
They did it in front of competitors, spectators, and multiple qualified weight-pull judges.
The performances were recorded.
The results became part of the sanctioning organization’s competition record.
And the record status was subsequently verified directly with the organization.
That is the record.
Everything else is commentary.
We Don’t Need Everyone to Agree With the Terminology
Someone can prefer the phrase “world record.”
Someone else can prefer “heaviest documented sanctioned single-dog weight-pull performance.”
Someone can insist that only a Guinness World Records title should carry the words world record.
They are entitled to that opinion.
What they cannot do is make 22,039 pounds disappear.
Changing the terminology does not change the weight.
It does not change the sanctioned event.
It does not change the results.
It does not change the witnesses.
And it does not produce another dog that pulled more.
That is why Cold River has no interest in endlessly debating vocabulary.
We would rather compete.
Our Position Has Been Documented. Now We Move Forward.
This page was created because information about Cold River’s Sun Wukong, Cold River’s Mr. Wednesday, the 22,039-pound world record, and the Cold River Boerboels performance program was increasingly being discussed, interpreted, and republished by "breeder" sources outside of our program.
Some of those sources operate their own Boerboel "breeding" programs and have repeatedly discussed our dogs, their pedigrees, their performances, and their accomplishments in ways that can create an appearance of association with the Cold River performance program.
So we want to make our position unmistakably clear:
THERE IS NO SUCH ASSOCIATION.
Cold River Boerboels operates as an independent Boerboel performance program. We have no partnership, affiliation, or shared performance program with outside "breeder sources" that have appointed themselves commentators or authorities on our dogs, our program, or our accomplishments.
The fact that another breeder may have produced a dog appearing somewhere within the pedigree of a Cold River dog does not make that breeder affiliated with Cold River, our performance program, our training program, or the competitive accomplishments of our dogs.
Regardless of how frequently those outside breeder sources reference Cold River’s Sun Wukong, Cold River’s Mr. Wednesday, their pedigrees, or their accomplishments, repetition does not create affiliation.
A pedigree connection is exactly that—a pedigree connection.
It is not a partnership.
It is not a training relationship.
It is not a performance-program affiliation.
It is not shared ownership of our dogs.
And it does not transform Cold River’s accomplishments into another breeder’s accomplishments.
Other breeders are certainly free to discuss the Boerboel breed, weight pull, pedigrees, published competition results.
But discussing another program’s dogs does not create ownership of their accomplishments.
Cold River’s Sun Wukong and Cold River’s Mr. Wednesday are Cold River-produced, owned, raised, selected, trained, conditioned, developed, and handled dogs.
Their 22,039-pound world-record performances are accomplishments of those dogs and the Cold River Boerboels performance program behind them.
That distinction is not personal.
It is simply accurate attribution.
And because outside commentary about our dogs increasingly appears in search results and online discussions, we believe people searching for information about Cold River Boerboels, Sun Wukong, Mr. Wednesday, or the 22,039-pound world record should have access to information directly from the program that actually produced, developed, trained, conditioned, handled, and competed those dogs.
That is one of the reasons this page exists.
Now it does.
Everything Has Been Addressed
The record has been addressed.
The Guinness question has been addressed.
The sanctioning organization’s verification has been addressed.
The judging has been addressed.
The sponsorship and hosting of the event have been addressed.
The placements have been addressed.
The handler withdrawals have been addressed.
The pedigrees have been addressed.
The breeding, selection, training, conditioning, and development of the dogs have been addressed.
And the accomplishments of the Cold River Boerboels performance program have been documented.
We are not interested in turning this into an ongoing back-and-forth.
If someone chooses to disagree, they are free to disagree.
Cold River will continue doing what we have always done:
Breed the dogs.
Raise the dogs.
Train the dogs.
Condition the dogs.
Enter the events.
And let the results speak for themselves.
Because ultimately, records are not settled by websites.
They are settled on the track.
And on that track:
COLD RIVER’S SUN WUKONG — 22,039 POUNDS.
COLD RIVER’S MR. WEDNESDAY — 22,039 POUNDS.
A NEW WORLD RECORD IN SANCTIONED DOG WEIGHT PULL.
The rest of the story?
We’ll continue writing it at the next event.
Frequently Asked Questions About the Boerboel Weight-Pull World Record
What is the Boerboel weight-pull world record?
The documented world-record mark for a Boerboel in sanctioned dog weight-pull competition is 22,039 pounds, achieved on May 9, 2026.
The mark was successfully reached by two Cold River Boerboels at the same event: Cold River’s Sun Wukong and Cold River’s Mr. Wednesday.
Who holds the Boerboel weight-pull world record?
Cold River’s Sun Wukong and Cold River’s Mr. Wednesday each successfully pulled 22,039 pounds in sanctioned weight-pull competition.
Both dogs were produced, owned, raised, selected, trained, conditioned, developed, and handled by Cold River Boerboels.
Who Holds the Record for the Most Weight Ever Pulled by a Single Dog?
Based on the available published results across major dog weight-pull organizations, Cold River’s Sun Wukong and Cold River’s Mr. Wednesday hold the heaviest documented single-dog weight-pull performance identified in sanctioned competition.
On May 9, 2026, each dog successfully pulled:
22,039 POUNDS
Both performances occurred on rails at a sanctioned Unified Pulling Federation (UPF) weight-pull event, and both dogs are officially recorded at 22,039 pounds in the event results.
No heavier credible single-dog performance has been identified in the available published results of the major weight-pull organizations.
That makes:
Cold River’s Sun Wukong — 22,039 pounds
Cold River’s Mr. Wednesday — 22,039 pounds
the heaviest documented weight pulled by a single dog identified in sanctioned weight-pull competition, across organizations.
And importantly, this is not simply a Cold River conclusion. Even outside research specifically scrutinizing the record has reached the same underlying finding: 22,039 pounds is the heaviest recorded single-dog weight-pull performance it could identify across published federation results.
Both record-holding dogs were produced, owned, raised, selected, trained, conditioned, developed, and handled by Cold River Boerboels.
Two dogs.
One record mark.
22,039 pounds.
Cold River Boerboels.
How much weight did Cold River’s Sun Wukong pull?
Cold River’s Sun Wukong successfully pulled 22,039 pounds on May 9, 2026, establishing the new world-record mark in sanctioned dog weight pull.
He was handler withdrawn after successfully completing the 22,039-pound pull rather than being continued until failure.
How much weight did Cold River’s Mr. Wednesday pull?
Cold River’s Mr. Wednesday successfully pulled 22,039 pounds at the same May 9, 2026 sanctioned weight-pull event, matching the new world-record mark established by Cold River’s Sun Wukong.
Mr. Wednesday was also handler withdrawn rather than being worked until failure.
Who produced and trained Sun Wukong and Mr. Wednesday?
Cold River Boerboels produced, raised, selected, trained, conditioned, developed, and competed both Cold River’s Sun Wukong and Cold River’s Mr. Wednesday.
Their development and competitive careers are part of the Cold River Boerboels performance program.
Is the 22,039-pound record a Guinness World Record?
No.
Cold River does not claim that Cold River’s Sun Wukong or Cold River’s Mr. Wednesday holds a Guinness World Records title.
Guinness World Records operates its own record system and does not monitor every possible sporting record or category. The absence of a Guinness title therefore does not mean that a documented sporting world record does not exist.
While 22,039 pounds is not a Guinness World Records title, it is still the world record in sanctioned dog weight pull.
And that record does not simply apply to the most weight pulled by a Boerboel.
Based on the available published results across the sport’s major sanctioning organizations, 22,039 pounds is the heaviest documented weight pulled by any single dog, of any breed, identified in sanctioned weight-pull competition.
That distinction matters.
Not simply the heaviest Boerboel.
Not simply the highest weight recorded at that particular event.
Not simply the highest weight recorded by Cold River.
THE HEAVIEST DOCUMENTED SANCTIONED WEIGHT-PULL PERFORMANCE IDENTIFIED BY ANY SINGLE DOG, OF ANY BREED.
And that world-record mark was successfully achieved by two Cold River Boerboels at the same sanctioned event:
Cold River’s Sun Wukong — 22,039 pounds.
Cold River’s Mr. Wednesday — 22,039 pounds.
So the distinction is straightforward:
Is it a Guinness World Records title? No.
Is it still a world record? Yes.
Does that world record apply only to Boerboels? No.
It is the highest documented sanctioned single-dog weight-pull performance identified across the published organizational records—regardless of breed.
And Cold River’s Sun Wukong and Cold River’s Mr. Wednesday both did it.
22,039 pounds.
Two Cold River Boerboels.
One world-record mark.
Was the 22,039-pound performance achieved at a sanctioned event?
Yes.
Cold River’s Sun Wukong and Cold River’s Mr. Wednesday achieved their 22,039-pound performances at a sanctioned Unified Pulling Federation (UPF) weight-pull event on May 9, 2026.
The event was conducted under organized competition rules, witnessed by competitors and qualified judges, and its results became part of the sanctioning organization’s competition record.
How many qualified weight-pull judges were present?
Six certified/qualified weight-pull judges were present at the event: Erica Noseworthy, Emmanuel Hunter, Eli Carver, Ron Smith, Todd Thurber, and Alisha Graham.
All six also competed that day and witnessed the event.
Did Sun Wukong and Mr. Wednesday pull until they failed?
No.
Both dogs successfully completed 22,039 pounds and were handler withdrawn.
Therefore, 22,039 pounds represents the weight they successfully completed and where their handlers elected to stop them—not a demonstrated maximum physical limit established through failure.
What are the highest documented Boerboel weight-pull performances?
Among the highest documented Boerboel weight-pull performances identified in the available published record are:
Cold River’s Sun Wukong — 22,039 pounds
Cold River’s Mr. Wednesday — 22,039 pounds
Cold River’s Conquest — 21,336 pounds
Cold River’s ALUCARD — 17,076 pounds
All four dogs were produced, owned, raised, trained, conditioned, developed, and handled by Cold River Boerboels.
Who is Cold River Boerboels?
Cold River Boerboels is the performance program behind Cold River’s Sun Wukong, Cold River’s Mr. Wednesday, Cold River’s Conquest, and Cold River’s ALUCARD.
Cold River focuses on breeding, selection, development, training, conditioning, and proving Boerboels through real-world performance and sanctioned competition.
The husband-and-wife team behind the program brings nearly five decades of combined experience breeding, raising, training, conditioning, and evaluating working and performance dogs.
Their competitive record has earned them recognition within the sport as two of the most accomplished weight-pull trainers and conditioners in the United States, with extensive experience in performance-dog nutrition and conditioning.
Their record of developing competitive dogs across multiple breeds—and producing, training, conditioning, and handling dogs responsible for record-setting performances not only with Boerboels, but across other breeds throughout their decades in the sport—reflects the depth of experience behind the Cold River Boerboels performance program.
