Boerboel Size, Growth and Health

At Cold River Boerboels, we emphasize proactive measures to minimize the risk of bloat (gastric dilatation-volvulus or GDV), a serious and potentially fatal condition common in large, deep-chested breeds like Boerboels. At Cold River, our adult dogs are fed once a day, in the evening, when they are getting ready to lie down and settle in for the night. We do that on purpose because of bloat: an evening meal is followed by hours of calm rest instead of activity. Our puppies are fed differently. They get several small meals throughout the day, usually two to three, and that schedule is adjusted and settled as they mature into adults. Our working dogs getting ready for competition get one meal a day. Many owners of deep-chested breeds also choose to split the daily portion into two meals, so talk with your veterinarian about the schedule that is right for your dog. Avoid vigorous exercise at least one hour before and two hours after feeding to prevent excessive stomach movement. Other sensible management includes calm mealtimes, appropriate portions, and slowing down dogs that gulp their food. Owners of large breeds can also discuss preventive gastropexy with their veterinarian; it does not prevent gas or bloat itself, but it is intended to reduce the risk of the stomach twisting. Owners should observe their dogs closely for symptoms such as persistent unproductive retching, a visibly swollen or distended abdomen, restlessness, excessive drooling, and signs of distress or weakness. If any of these symptoms arise, immediate veterinary attention is critical, as GDV is a medical emergency requiring prompt intervention. Following these guidelines helps ensure the health and safety of your Boerboel, aligning with Cold River Boerboels’ commitment to responsible breeding and lifelong care.

A: Boerboels generally have an average lifespan of 9 to 11 years, which is typical for large to giant breeds. As a giant breed, Boerboels experience unique aging factors such as joint stress, slower metabolism, and heightened risk of weight-related health issues. At Cold River Boerboels, we emphasize responsible breeding paired with education on optimal care to maximize longevity. One of the most effective ways to support your Boerboel’s health and extend their lifespan is through vigilant weight management. Maintaining a healthy weight reduces strain on joints and decreases the risk of diabetes and heart conditions common in giant breeds. We provide guidance on balanced nutrition, portion control, and appropriate exercise tailored to your dog’s growth stage and lifestyle. By partnering with Cold River Boerboels, you receive not only a well-bred companion but also expert advice to help your Boerboel live a longer, healthier life.

Boerboels are generally a strong, robust breed, but like any large breed, there are some health concerns to be aware of. This can include hip and elbow dysplasia, certain cardiac conditions, eyelid issues, and bloat. Good breeding practices, health testing, keeping dogs lean and fit, and allowing steady growth in puppies all play a role in producing and maintaining sound dogs. At Cold River, we focus heavily on structure, movement and health testing in our breeding decisions.

A limp that shifts between legs is the classic sign of panosteitis, which can affect one long bone and then another during growth. Other conditions can cause limping too, so a shifting limp still needs a veterinary exam. Read our full guide to growing pains in Boerboels.

Yes. X-ray changes commonly lag 10 to 14 days behind the first signs, so early X-rays can look normal. Your veterinarian may recommend repeat X-rays if the limp continues or changes. Read our full guide to growing pains in Boerboels.

That hasn't been proven. One 2002 pilot study suspected protein-rich, high-calorie foods, but presented it as a hypothesis. A 1991 study in Great Dane puppies found protein levels up to 31.6% had no demonstrable effect on skeletal development. Stronger evidence points to excess calories and calcium. Read our full guide to growing pains in Boerboels.

No, not unless your veterinarian prescribes them. Veterinary guidance says to avoid adding calcium, phosphorus, vitamin D or extra calories for young, growing dogs. Feed a complete diet suitable for growth and keep the puppy lean. Read our full guide to growing pains in Boerboels.

Not during a painful episode. Stop weight pulling, dragging, sprinting, jumping and treadmill work, follow your veterinarian's rest plan, and return to exercise gradually. Puppies shouldn't pull real loads anyway until they're physically mature. Read our full guide to growing pains in Boerboels.

No. The FDA warns that human pain relievers, including aspirin, ibuprofen, naproxen and acetaminophen, can harm dogs. Use only medication your veterinarian prescribes for your dog. Read our full guide to growing pains in Boerboels.

If the limp lasts more than a day or two, or the pain is severe, sudden or getting worse. A puppy that won't bear weight, or that also has a fever or won't eat, should be seen the same day. Read our full guide to growing pains in Boerboels.

Usually. The long-term outlook is excellent, and pano typically resolves as the dog reaches skeletal maturity. Episodes can recur during growth, often up to about 18 months of age. Read our full guide to growing pains in Boerboels.

They can contribute, but recurring ear infections don't automatically mean a food allergy. Veterinary research lists ear inflammation (otitis externa) among the ways food reactions show up in dogs, along with itching and skin infections. Environmental allergies, ear mites, foreign material, moisture and ear shape can all play a part too. Only a strict elimination diet trial under your veterinarian's guidance can confirm a food allergy. If your Boerboel's ears keep flaring, have them examined. Read our guide to Boerboel ear infections, food allergies and recurring ear problems.

Boerboels come in a variety of body types and compositions, which leads to a significant range in weight. Male Boerboels typically weigh between 120 and 220 pounds, while females usually range from 100 to 180 pounds. Compared to a Cane Corso, the Boerboel is generally larger in size, though their builds are somewhat similar. In terms of weight, the Boerboel is closer to that of an English Mastiff.

Male Boerboels generally weigh 130 to over 200 pounds and stand 24 to 29 inches tall, while females typically weigh 100 to 175 pounds and stand 22 to 27 inches tall.

Boerboels do most of their height growth during the first year, usually reaching close to their adult height around 12 to 18 months. They continue filling out in bone, muscle, chest, head, and overall mass until roughly 2 to 3 years old, and some larger males may continue maturing beyond that. At Cold River Boerboels, we focus on sound, steady development rather than trying to rush growth. Young dogs should be given time to mature before being asked to do heavy conditioning or demanding physical work.
