Demodex Canis

Demodex canis are microscopic mites that normally reside in a dog's hair follicles. If your dogs immune system is compromised, that's when the mites start running the show, causing demodectic mange. In case you're worried, careful studies have shown, that demodex canis mites are not really contagious to humans, as this type of mite thrives from living on dogs. Human beings typically have mites of their own, such as Demodex folliculorum and Demodex brevis that live in the eyelashes, but you shouldn't get your dogs mites. In fact, when a dog gets demodectic mange, they will not usually be contagious to even other dogs, unless the other dog has a weakened immune system as well. Demodex Canis Mite

Symptoms of demodectic mange may include hair loss, circular bald spots, and red scaly crusty dry skin. It usually begins to develop around the face and paws. If it is a mild case, with just one or two small spots, your veterinarian may only recommend a healthier diet and let the situation resolve itself without treatment. For what is termed "generalized" demodectic mange, where it has spread to larger areas, a topical treatment will be prescribed along with an antibiotic to treat secondary bacterial infection.

The best prevention against demodex canis mites turning into mange, is to stay in good health. This includes good nutrition, proper exercise, and positive interaction.
