I had a friend with the most amazing pit ever - extremely well trained. He would play wrestle with you and when it got too rough or you wanted him to stop, you would just have to say "nine" and he would stop immediately and lay down on the floor. My friend was not home, when the dog got out of her backyard. The police were called, and shot and killed the pit bull, stating the pit was attacking another small dog (some sort of terrier). The terrier had no marks on it. I reason to believe if the pit had been attacking the terrier, the terrier would have been at least beaten up a little. It's a tragedy when good family dogs are lost to cultural assumptions.
