Demodectic Mange is caused by the Demodex Mite that ALL dogs have and lives in the hair follicles in the skin. These mites are transferred to them as puppies from their mother when suckling. Usually, because their numbers are small, they cause no problems but in some cases (possibly when associated with a hereditary or immune problem) they can increase and cause symptoms.
* Symptoms can be restricted to small areas or be widespread.
* The mites can cause hair loss and skin reddening on the face and front legs.
* Often there is evidence of crusty skin areas and severe dermatitis.
* Unlike Sarcoptic mange (scabies), it is not particularly itchy.
Most cases of localised infection clear up on their own after several weeks and treatment may only be required if it worsens into the generalised form. If it does, this may require clipping, medicated bathing and repeated injections to kill the mites.
Prevention: Dogs with severe demodectic mange should not be used for breeding as there is some suggestion that the tendency to the disease may be inherrited.
