Call her breeder and ask if there is any history of Zinc Responsive Dermatosis in her line. It's fairly common in purebred Siberian Huskies.

Muskwa has it. It does take awhile to clear up once treatment starts, 2-3 weeks. Muskwa gets 75mg of Zinc, just a human supplement pill, every day. Cheap and easy to treat. He can go three days without it before the sores reappear. They appear anywhere his fur is thin--eyes, genital area, belly, ears, ect. He needs more zinc when he is working alot or under any kind of stress.

We did get a firm diagnosis--only done through a skin biopsy. But if it's in her line, you may be able to start her on a supplement right away and see if she responds. It's extremely difficult to overdose a dog on zinc; it would need to be a massive dose. They just pee out whatever they don't need usually.

Good luck, I hope it's nothing serious.
