Mange Symptom Checker

Mange, especially the Demodectic variety, is frequently misdiagnosed. Sarcoptic, Demodectic and Cheyletiella mange mites are difficult to detect and have symptoms that resemble each other and other health problems. When treatment for the misdiagnosed condition fails or worsens the problem, owners often have to figure things out on their own.

Of course a positive skin scraping is the best indicator. If this is the case, knowing the symptoms listed below will help you develop your treatment plan.
