I agree. My dog was an insatiable chewer until he was 2. He earned his way out of the kennel by good behavior while unsupervised for short periods. Now I never have to crate him. Just remember that all pups chew, it's how they cut their teeth, but with a little effort, he can be taught what's ok to chew on (toys) and what's not (blankets). Good luck!
Ditto.
Be sure to always have plenty of things available that he IS allowed to chew on. There's many means of punishment...administer what works for your pup
when you catch him in the act and reward him when he chews on what's his.
Some questions, though; How old is your dog? As said, puppies cut teeth and then, as their adult teeth come in, they chew to aid in that process. Also, is he only chewing when unsupervised? A lot of dogs suffer from seperation anxiety or have abandonment issues...they stress when you leave and, much like you'll break out the potato chips or ice cream when you're upset, they chew on things.
To add, when selecting chewies for the pup, I suggest raw-hides and similar products. Some care to find a product that is pet-safe is important, though...avoid white raw-hides and packages that do not list ingredients. It's usually pretty easy to find a suitable pig-ear variety, but raw-hides are becoming rare.
I also think booda products are worth looking at:

I'll be trying these out this week I think.
