I really don't remember. I had forgotten about it until I read your post. I do remember that I had to take my dd to the dermatologist because what her Dr. gave us didn't work. I was going through the same with the dog, what the Vet gave us didn't work and I was ready to go to the vet dermatologist when I was cleaning out the bathroom and came across this old bottle of shampoo. I thought I'd give it a try. It worked. I do remember having use it for a few weeks and bathing the dog every 3-4 days.
With a husky you do need to be sure to get that thick coat dry after a bath, because the dampness of the bath can cause skin problems
