On of the dogs at the kennel is a biter! His name is Knave and he is a six month old collie. Since he was a couple months old he has always bit me. He takes him front teeth and bites and holds on to your skin. He gets in very sensitive spots like under your butt, your thigh, the bend of your knee, your elbow, and worst of all the palm of your hand. I have always grabbed his mouth and said "no Knave! no bite" and he still doesnt stop to this day. And i have been doing that for months. I have also tried ignoring him, and yelping. He is starting to break blood and it is really painful!!!! He only does it when he is exited. After he is calmed down he doesnt do it anymore. This is one of my favorite dogs because he has loads of fun personality. but this is NOT fun and it needs to stop pronto!
