Q. I believe my dog has demodex mites, how can I be sure?

Answered By

A. Unlike most skin parasites, demodex mites do not live on the skin, they live in the hair follicles, therefore it is not possible to spot them on hair or skin. Deep skin scrapings must be performed and it is necessary to visualize the mites under a microscope.

Demodicosis is most commonly seen in puppies and young dogs. Localized forms, which usually affect the skin on face and/or legs, often do not require treatment and symptoms resolve spontaneously.

On the other hand, generalized forms of Demodicosis affect the whole body, causing skin crusting, irritation and hair loss. These forms require treatment, in many cases during several weeks, or even months.

There are various treatment options depending on the severity of symptoms. Demodicosis can be treated with shampoos and other topical skin preparations, spot-on medications, tablets or anti-parasitic injections.

Finally, generalized Demodicosis in adult dogs is the most serious form as it results in suppression of the dog's immune system. This form of Demodicosis develops secondary to internal diseases like hypothyroidism, Cushing
