Cheyletiella dermatitis, known as "walking dandruff," is caused by Cheyletiella mites. Symptoms include skin irritation, dandruff, and hair loss. Often, the mites are visible to the naked eye. Cheyletiella mange may affect dogs, cats, rabbits and humans. Fortunately, it is easily treated. Take your pet to the veterinarian to make sure the problem is Cheyletiella mites. The vet may prescribe one or several treatments.

Selenium-Sulfide Shampoos
-
For mild cases of Cheyletiella mange, a selenium-sulfide shampoo can be used once a week for five weeks. In addition to killing the mites upon contact, this shampoo may also relieve itching and scaling. Selenium-sulfide shampoos can be purchased over the counter and are often the same shampoos used to treat dandruff and flaking in humans.
Insecticide Dips and Sprays
-
Lime-sulphur dips can be applied weekly to dogs, cats and rabbits for three to four weeks. Amitraz dips can be used with dogs only. Generally three amitraz dips are given at two-week intervals to treat infected dogs. Dogs and cats may also be treated with fipronil spray. Your vet should supervise any treatment with insecticides.
Ivermectin Injections
-
For extreme cases of Cheyletiella mange in dogs, ivermectin injections can be administered to kill the mites internally. However, ivermectin may be toxic for some breeds of dogs. Avoid ivermectin injections for beagles, collies, shelties and any mixes of these breeds.
