I have evaluated a couple hundred on the end of a leash to determine their adaptability to life among humans.
A couple hundred "pitt bulls"?
I do not train pitts as attack dogs because an attack dog has to be completely and totally controllable and there are many other breeds that are much better to work with.
So without ever attempting to train them you hold that they are incapable of being trained?
...incapable of being completely and totally controllable?
Which breeds of dogs are "completely and totally controllable"?
How many Pitts have you professionally trained or evaluated?
None, it is not my occupation.
My avocation is to ask questions, do research
and observe the behavior of dogs with which I come into contact.
I attempt to present facts, make valid generalizations
and advocate for responsible dog ownership.
