Registered Breeders

with Boerboel Africa Breed Society in Australia.

                      The Ysterberg bloodline of the South African Mastiff® was developed in the 1940s under the rigors of farm life in the rugged Ysterberg mountain area of South Africa, bred for form and function as a farm and guardian breed, not for purposes of exhibition and commercial sale. The Ysterberg farm dogs preceded the registration and recognition of large native dogs which came to be called “Boerboels” and became part of the gene pool when the Boerboel was created. For the past decade, dedicated breeders of the Ysterberg bloodline continued to breed their dogs under a controlled program of the Ysterberg Mastiff Breed Council (YMBC).

To address confusion related to the name attached to the “Ysterberg Mastiff” and “Boerboel”, we’re excited to announce that as of November 2019, we’re rebranding. As part of our rebranding strategy, our organisation’s name will change from Ysterberg Mastiff™ Breed Council to South African Mastiff® Breed Council – powered by Ysterberg since 1948.

What is a Ysterberg Mastiff ?

Here is just some background so that you can have a better idea of what a Ysterberg Mastiff is.

. They Ysterberg farm dogs / boer dogs have a written history dating back to the early 1940s. When the first Boerboel organisation was founded (SABT) in 1983, the Ysterberg dogs were included as they were within the parameters of what the founders were looking for in the Boerboel. In 2010 YMBC decided that their vision for the dog and that of the Boerboel organisations are very different and in order to protect the Ysterberg bloodline, the quality of the dogs, the health and temperament YMBC are taking back the whole Ysterberg bloodline away from the Boerboels, and that is how the Ysterberg Mastiff Breed Council started. Having this precious history and bloodline, it has to be to protected.

Therefore, after an investigation and vetting process, and YMBC do accept certain Boerboels into our foundation stock register and help those breeders to improve on them and work towards the look, health and temperament of the original Ysterberg dogs. You will notice that they are indeed a frame size or two bigger than the Boerboel

What is a Boerboel ?

The Boerboel is a Mastiff breed from South Africa.

 Bred for Guarding You and your Family, they are loyal to their families but aloof with strangers. They are extremely large, powerful dogs that were bred to work independently as guardians and therefore should be supervised around strangers. This is not a breed you can take to your children’s sports games.( this can be done with proper control of your dog ) They are deeply loyal and affectionate with their families.

We're sure you'll be happy dealing with us. Look around our website and if you have any comments or questions, please feel free to contact us.
