How do I stop him biting?
Title says it all really, Barney has turned into a pitbull!! He keeps biting us, sometimes when he is cross, sometimes with no warning at all. Poor Millie gets the worst of it as she isn't as good at seeing him coming, and he often bites her without warning while they are playing. We've tried shouting no at him, he hates being shouted at and it often makes him cry, but it makes no difference to the biting. We tend to just remove him and ignore him completely so he gets no attention for it but I can't expect Millie not to squeal when he bites her (he's left a full set of teeth mark bruises twice this week). Any ideas? He's only 16 1/2 months so too young really for a naughty corner which is what we normally use with Millie when removing attention doesn't work.
