Could My Dog’s Itchy Hindquarters Be Mange, and Is It the Same as Scabies?

Thank you for the detailed description, Amy. Intense itching that spreads to a second dog does raise the possibility of sarcoptic mange (scabies). It usually starts on the ear edges, elbows and belly, but it can also affect the legs and other areas. Fleas are another strong possibility, because flea allergy typically targets the hind end, legs and belly, and fleas can be hard to spot. Your dogs could also share an environmental allergy.

Mange and scabies are related terms: scabies is another name for sarcoptic mange, which is contagious. Demodectic mange is the other main type, caused by a different mite, and it isn't contagious and usually isn't very itchy. Zymox may soothe the skin, but it isn't a mite treatment, which may be why the spots return when you stop.

Because scabies mites are often missed on tests, vets frequently treat for it when the signs fit, using a prescription product for both dogs. For a dog who struggles at the vet, ask about anti-anxiety medicine before visits, a house-call vet, or muzzle training. Please don't rely on over-the-counter remedies, which aren't proven to clear mange. Read more about sarcoptic mange and how it's treated.
