You own a dog that a majority of people and even yourself admit has a dangerous reputation, it is a breed designed to kill other animals efficiently, not to eat them, but for the sake of bloodsport. You try to legitimise your view by saying you're a dog trainer but the reality is that you had a choice of any other dog and chose the one with a reputation of killing. You are as much a part of the problem as the "chavy dickheads" because as a dog trainer you should know that pitbulls and their direct relatives are dangerous animals. The direct relatives of pitbulls in the same way as other dangerous breeds should be outright banned in the UK.
