So...I am a massive believer in..its the owner not the dogs but we know pitties were bred to fight. I've heard the xl bullies are a mix of American bulldog x pitbull then I heard they were a mix of English bulldog American bulldog pittball and staff. I have had many breeds and my American bulldog was not my favourite...only because he wasn't given the proper time and training love and attention he deserved (this was out of my control ..but can illiterate if needs be) anyways. I know any breed including xl bullies can be the most fantastic dog, but right now in the UK they ate falling into the wrong hands. Inexperienced ppl who have no f ING clue how to care for these powerful dogs and its getting out of control... thought???
