In 2010, however, like-minded individuals came to realize that their vision for the Boerboel was very different from what Boerboel organizers had in mind. When the first Boerboel organization was founded in 1983, Ysterberg dogs were included because their conformation fell within the parameters of what founders were looking for in the Boerboel. Some sources indicate, however, that the Ysterberg Mastiff was part of the foundation stock of the Boerboel in other words, a breed unto itself.

Bred by Klaas van Waveren before the Boerboel was officially recognized, the Ysterberg has been described the oldest living bloodline in Boerboel history. Some write that the Ysterberg Mastiff is a Boerboel bloodline that existed in the early 1940s in South Africa. As it turns out, the answer isn’t very clear, at least not to us. We wondered if this was a breed unknown to us, or something else. While doing a little research on the Boerboel, we came across several mentions of the Ysterberg Mastiff.
