Some friends had very bad skin allergy problems with one of their labs to the point where it seemed that only drastic measures would work. The wife located a vet clinic that include holistic approached in their treatments and they found that a minor enzyme supplement cured their problem.

No idea if it would help your dog, but it is an option to consider.

Also, glucosamine for humans does wonders for dog joint pain. I take 2 tablets a day and the older greyhound takes one. For my breed (greyhound), it is highly recommended once the dogs reach 5 years.
