Cold River Boerboels

With nearly five decades of combined experience in working, training, breeding, and competing with dogs, we are proud to bring our expertise to the world of South African Mastiffs, better known as Boerboels. Our mission is simple: to breed the best stock possible. We prioritize temperament, conformation, workability, and health in every pairing, ensuring our dogs are not only beautiful and functional but also stable, confident, and well-balanced. Our dogs live and thrive on our farm, where they enjoy constant interaction with children, other dogs, cats, poultry, and livestock. Bred for purpose and functionality, all our Boerboels are registered, DNA tested, and screened through OFA or PennHIP to guarantee their health and genetic integrity. Over the years, we have developed rigorous protocols to ensure the well-being of every dog in our care. Our top priority is to provide each puppy family with a happy, healthy, and well-adjusted new member. As breeders, we are deeply committed to breed preservation.

Boerboels remain a rare and unique breed in the USA, with perilously low numbers and diminishing opportunities for their original working roles. We breed to preserve and enhance the breed, ensuring they remain workable dogs with size, function, purpose, and a temperament suited for both family life and guardianship.

Join us in our mission to protect and promote this remarkable breed. Explore our program and discover why we are dedicated to breeding Boerboels that excel in temperament, form, and function
