Ok, Maverick has such a strong herding drive (well atleast I think it is) I don't know what to do. He's constantly biting the other dog's ankles and he will do that to just about anyone me, my husband, my stepkids, strangers. Although he hasn't done it to Emily yet. Is this herding or aggression? If it is herding what can I do about it. I don't want to try and stop him from doing something that comes natural to him but I want him to find a more appropriate thing to herd than people (because it really hurts ). Can I give him tennis balls or something to use as a herding device or just live with the fact that he is a herding dog and is going to bite my ankles forever. Could this possibly just be a puppy thing?
