When I had puppies they were gated off entering rooms I could not watch them. Gate off all rooms, only allow him in if you can watch him. I had a puppy that loved the taste of Bitter Apple, just a heads up, what works for some dogs, do not always work for all dogs. When she would start on the coffee table legs, I would tell her no in a very firm tone and give her toys.
Puppies should never have free roam without supervision, they get into things you can't even imagine, so many things around the house can be very harmful, even fatal. As frustrating as this is, enjoy every day with Elvis, they grow so fast.
Meant to add, Taylor is correct about the rawhides, do not give them to any dog.
