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.
