Congrats on your new pup! He's adorable!! What breed is he/she?
Definitely don't let him chew on your things. What seems cute now, won't be when your things are in shreds. Get him some chew toys and every time he starts chewing on something inappropriate, take it away and substitute one of his chew toys. The best prevention is to keep things put away so he can't get to them -
