I'm going through the same thing so I understand your frustration. I've found the bitter apple spray works - I spray it every few days on anything he's taken an interest in.
Welcome to the wonderful world of baby bullies! Christine gave great advice...NO...and redirect. I thought I would lose my mind with Dudley as a puppy...walls, furniture...anything. Was able to redirect him...but they are chewers...now, Dudley chews on nylabones and antlers...loves to chew...he's a good boy now...but he's 3. I don't want to scare you, but the chewing goes on for quite a while, because their jaws grow for so long...18 months to 2 years. Hang in there!
