A few years back an acquaintance wanted to find a home for a Pitbull puppy. She worked for a vet that was asked to put it down, he ask if it was OK to find it a new home.
I occasionally see them out walking, at a glance you would not take it for a Pitbull. Just a happy dog walking with its family!
A pit bull is like having a fully-loaded pistol where kids can find it except this pistol pulls its own trigger.
