I know nothing about Pork Chop and I wish him well. But I believe BayKat when she says he took after the Yorkie and knocked people down in his desire to run amok. Sorry. That doesn't make him vicious, but it does make him a dog that needs special handling.
I'm going to feed the fire by saying if an animal was accused of biting a child 3 times, would you wait that long to get rid of him/her? Honestly!
My bad toddlers knock my son, his g/f, my friend the neighbors kids down. Ok, next! Its their way to show affection. It's the breed! Deal with it or No deal! Get it?
PC went after every animal we had today at the event. Guess what? It took one of our trainers to say that is not a good thing and he learned. M took PC and laid him down physically. He nipped and nipped again. M said he's been spoiled for 2 years with no obeinance. (love you jwwwb) It's not his fault. He didn't nip again! He's 4 mind you. Boxers are that smart at that age if you HAVE the TIME!.
God I hate to open a can of worms again.
