Allergies, I believe!! Ruby was really scratchy and had thiose bumps when we got her...I used puppy shampoo for the first bath (although she is one, this is what I already had)...she still scratched, so at PetCo I found "Four Paws Hypo Allergenic medicated shampoo for pets with aloe vera & coal tar used by Veterinarians for the relief of dandruff, dermatitis, itching and dry skin." I have used this three times now (weekly bath) and with each washing see a softer coat and much less scratching. The bumps were gone after the first washing. The vet said coal tar and oatmeal are essantial ingredients for skin problems. The bottle is ugly (sorry, I'm in advertising so I notice these things)..it is white with a picture of a husky... hope it helps...oh, by the way, do you use any kind of carpet sprinkle before you vacuum...?? That could be a problem.....
