Do you know which dog is the most dominant one? I've read that it's best to show a little favoritism to the dominant one (by petting them first, feeding them first etc) which helps them maintain their 'status quo' as the dominant one, and decreases fighting.
I've found the best way to stop mine from fighting is to avoid the things that set them off. I have to separate them to feed them, if I give them bones I have to do it simultaneously for both or they fight over one bone, and I can't let the puppy go into the older dog's crate, or the older dog into the puppy's pen, or they get angry. |
