Licking

When will this stop? Jasper has been tormented by the itchies. It started in July. Just licking his paws a little. Then it turned into full blown chewing & biting his feet. I sware he's going to rip his feet right off his legs. He is raw fed. He's been on commercial raw (Nature's Variety, Aunt Jeni's, Abady ) and homemade raw recipe. I did an elimination diet with just raw turkey and sweet potato. He is given Coconut oil for the omega's, Thorne Small Animal Antioxidant, probiotics, enzymes. My gut instinct is it is environmental not a food allergy. He walks one mile every day, trains 5 days a week in obedience, brushed & massaged every other day, bathed in oxyfresh shampoo weekly or every other week.

He's been seen by a holistic vet. He was given a chinese herb and homeopathy remedy. She also did accupunture with homeotox injections at the accupressure sites. I want to stay away from predisone since it suppresses the immune system.

Any suggestions/ideas?
