Abstract
In dogs, dermatitis due to mixed mite infestation is rare. During the five-year period of study, two dogs were identified suffering from dermatitis due to mixedDemodexandSarcoptesmites. Upon clinical examination dogs had primary and secondary skin lesions on face, around the ears, chin, neck, fore limbs and lateral abdomen. Microscopic examination of skin scrapings revealedDemodexandSarcoptesmites. Both dogs were treated with daily oral ivermectin at 100 to 400 μg/kg body weight as incremental doses, external application of amitraz and supportive treatments with topical antimicrobial shampoo. After completion of forty-two days of therapy, dogs were recovered from the dermatitis.

Summary
Canine demodicosis is a dermatologic disease that occurs when mites colonize the hair follicles and sebaceous glands [1]. There are no reports about the mixed infection of Demodex and Sarcoptes in dogs. This paper reports the rare occurrence of mixed demodectic and sarcoptic mange in dogs and their therapy.
