We now have a so-cute-it's-irritating pit bull puppy. Two problems: we've never had one, so we don't know how to train him and I'm allergic so the little pisser is making me itchy. I mean, quite literally, I've never had a dog (due to the allergy) so we are starting from scratch here. Focus: Dog training/new puppy knowledge. What are the do's and don't's?
