Why our dog chews off his pads
:confused: One of our dogs has been chewing off his pads. We've had him back and forth to the vet since Oct. 2007 for different treatments. He currently has three sore paws. We wrapped them, he quickly chews the bandages off, We purchased dogboots to protect the sore pads from the snow and ice when goes out for bathroom duties, but he has chewed them up. He is on antibiotic and now predisone. He was on antibiotics and phenobarb, without much relief. Antibiotics were for the open sores he made. They seem to tingle or itch, from what we have observed.
We had an ointment the vet gave us to use on him, paws seemed to get better for a few days, then he started in again, on another pad.
Is it his food, something on the carpet or floor, or anxiety. He never use to do this prior to 10/2007, he's 6 years old. His personality has changed, and he seems depressed. The phenobarb really changed his mood, when he was on it.
We want our dog to feel better. Any ideas?
