I have two siberian huskies, the male is 5, the female is 9 months. Both are spayed/neutered. The male is a wonderful dog 99% of the time, but every now and then something will set him off with another dog and he’ll bite them. Now he’s never inflincted any real damage, before now the most was just a small scrape every other bite has not left a mark at all. He has bit the female before but never left a mark. Yesterday he bit her pretty hard, it left a scratch and two small punctures on her muzzle (not deep). I didn’t see it happen, I think he was guarding a toy he really likes…though he’s never bit over a toy before (he will bite dogs, not people, over food). My question is, how am I supposed to react when I see him acting this way? I did smack his hind end and yelled at him, I never hit my dogs, but it was in the spur of the moment, I know that was completely the wrong thing to do…but I’m not sure what the right thing to do would be.
