Hi, If he is still a young puppy, then he is just learning about the leash etc. I would Not ever use a regular collar as they can cause trachea problems. You were smart to order a harness for him so you will have more control when he is on it. The step in ones are even better because they don't touch the throat at all. I'm not familiare witht the one you ordered but I'm sure it will work fine. I have 2 puppies that are 14 1/2 weeks and they run around here like crazy dogs chasing each other and even sliding in the wood floors, such clowns. Try not to worry I think he is just being full of himself and wanting to run and play..
Good Luck.
