Angus is a great dog. And he LOVES to make new friends, but the problem is, he nips them. On their rear/tail/back legs. It's not hard, but it scares and agitates the other dogs. I know he has some sort of herding dog in him (he looks like the spaniel half, however), but any advice as to stop this behavior? I feel bad for scolding him because he's not doing it to be mean, and I think it's instinct, but I'm afraid it's going to get him bitten. I introduced him to Jasper yesterday and poor Jasper didn't know what to think of this new dog nipping his behind. I think it actually kind of scared him.
