i asked that very same question a few days ago. i'm sure you can find the posts. there were some good suggestions. I bought a harness and leash. i'm attempting to get him to be used to the harness right now. I also bought a collar. he hates it. it's a bad collar, it stretches and is easy to put on, but no matter how tight it is he slips his head half way out and then it gets caught in his mouth and around his head. so don't buy any type of stretchy kind of harness.
