A Rescued Stray With Scaly, Patchy Hair Loss: What Kind of Mange?

Thank you for taking her in. Patchy hair loss with dry, scaly skin like dandruff can have several causes,

Possible causes include demodectic mange, which isn't contagious; sarcoptic mange (scabies), which is very itchy and spreads to dogs and briefly to people; Cheyletiella, a mite that causes heavy flaking along the back and can give people a short-lived rash; and ringworm, a fungus that causes round, scaly patches and can also spread to people and pets. A vet can often narrow it down with skin scrapings and hair tests, although sarcoptic mites can be hard to find, so your vet may suggest a treatment trial. Your other dogs may need checking too.

Please don't use home remedies such as motor oil, bleach or borax. They don't reliably kill mites and can burn her skin or make her ill if she licks them off. Until she's checked, keep her bedding separate and washed, wash your hands after handling her, and limit close contact with your other dogs. If you or anyone at home gets an itchy rash, see a doctor and mention the dog.

If cost is a worry, ask your vet about a payment plan, or look for a low-cost clinic, humane society clinic or veterinary school near you. Some shelters and rescue groups also help with vet costs for strays.
