Mange in Dogs
Mange is caused by mites. There are many varieties of mites that can infest your dog.
-
Types
-
There are four main types of mange. Otodectic mites are in the ear canal. Cheyletiellosis mites, walking dandruff, are large and walk on your dog's neck, back and head. Demodectic and sarcoptic mange mites burrow in the skin.
Transmission
-
Otodectic mange is contagious in animals but not people. Sarcoptic (canine scabies) and cheyletiellosis mange are contagious to dogs and sometimes humans. Demodectic mange, which is not contagious to people or generally to healthy dogs, is typically transmitted from a mother to her puppies.

Symptoms
-
Mange in the ears can cause scratching, head shaking and dark discharge. Sarcoptic and cheyletiellosis signs include hair loss and itching. Cheyletiellosis mites look like small, moving, dandruff-like flakes. Demodectic signs include hair loss and scaly red skin, but it is usually not itchy. All mange can result in bacterial infection from scratching.
Diagnosis
-
A vet makes a diagnosis by examining skin scrapings under a microscope to determine which mite is involved.
Treatment
-
Treatment varies depending on the type of mange, severity and your dog's health. Demodectic mange is the most difficult to treat and can recur or become generalized. According to VeterinaryPartner, the preferred treatment is ivermectin.
Warning
-
Never treat your dog's mange with motor oil, as it is toxic and can cause severe skin damage.
