I have spent over 20 years involved in dogs in a way that most people are not. I have trained my own, I have trained group classes, I have trained privately. I have shown in a number of venues and I have owned 2 pit bulls, altho they are not my breed of choice.
I will pit my general knowledge against yours any day. If you have greater experience than that, please let us know.
And people who hold to their personal anecdotal experience over broader statistics aren’t really too much worth attempting to reason with.
