My dog, Scout, loves other dogs but does not have very good doggie manners. When he sees another dog, he runs up to it, sniffs it quickly, and then starts to roughhouse with it (jumping on its back, biting, just rough doggie wrestling). Most often, the other dog does not want to play. Scout focuses all his attention on the other dog and will not listen to me. I would love for him to simply sniff the other dog and then move on with our walk. Scout is an eight month old German Shepherd mix. He has been around other dogs his entire life, both at the shelter and the homes he went through before coming here. He was neutered last week (6/5/12), but that did not seem to help the problem. Is this just a puppy thing? What can I do to get his attention back? I've tried using high value treats, but this rarely works. Any advice would be greatly appreciated.
