dog behavior chewing on everything

My dog chews his paws until they've tried everything raw, including the vet?

Anyone have any suggestions on how to get stop this destructive behavior?

This happened to a dog that had the diffrence last one, she bit her hair. Surprisingly, response was that he had lost a toy that she grew up with and loved. After some time I noticed his toy gone, I thought about it, that is, and never bit his hair again. It may be something psychological, that may well accually. You can also try to put something on the leg, like a light cloth or possibly something the dog does not like, like a little liquid. Hopefully the dog will not want to bite the leg of cloth or liquid flavor. This can also be a habbit itching or bad for the dog, you said you've tried the vet so I'm guessing its not an itch. Hope that helps … let me know how things go. Farewell Juan =)
