He is just a baby, and like a baby he needs to be watched and taught right from wrong. My girls would try to chew anything, towels, wooden chairs, table legs, but like someone mentioned only the "good stuff"
I work from home so when they were out and about I was able to keep an eye on them and tell them " no no" when they went to chew at something.
If you are not around try to crate him or get an ex-pen, it is great for keeping a puppy out of danger. You have to stop him from chewing everything otherwise he could try to chew an electrical cord or something equally dangerous. Just remember, he is at his baby stage and taught right from wrong he will eventually grow out of it.. My girls liked kongs when they were puppies, or the planet dog treat balls, they still love the planet dog treat balls, keeps them occupied for ages. Make sure that whatever you get the little guy, that he cannot get big chunks out of it. The Kongs and the Planet dog treat toys, are great for strong chewers, the planet dog is guaranteed as well, so if your puppy rips it apart they will replace it. Can you tell I love these toys.
Don't worry, he will eventually grow out of his chewing everything in sight stage. Hang in there.
