. 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.
