Wow that could be the original dogs close cousin. The second one I posted is suposed to be pure Boerboel. The first one is also claiming to be a pure Boerboel. I have recently read some interesting history on the BB concerning what is known as the ysterberg line. Ysterberg was breeding a mix of Old English Mastiff, Bullmastiff, Old English Bulldog, Bullterrier and even some Tosa. Then the hunt for the perfect BB begain and Ysterberg (Klass) did not originally participate. When Klaas passed away the Ysterberg bloodline was inherited by Stoffel Bloem who also did not like the way the breed standard was set so he went back to breeding the Ysterberg Mastiff. Many people call the Yrsterberg a Boerboel and many breed lines have Ysterberg in them. The ones that have a heavy Ysterberg ancesrty seem to produce these Ysterberg Mastiff looking like dogs. Which in my opinion are not what is comforming to the set standard of the BB. Even my Jade has Ysterberg in her lines dating way back in the late 1980's.
