First described in 1842
by Gustav Simon, a French dermatologist, Demodex
mites are normal skin inhabitants of many mammals, and > 140 species of Demodex have been identified (2 in humans, 3 in dogs).1 The
mites live in hair follicles as well as the sebaceous glands and ducts and feed off of sebum, cells, and debris from the epidermis.2, 3 In dogs, the
mites are
passed from the bitch to her puppies through close contact while nursing.
All pups that are raised naturally
by their mothers have demodectic
mites, because they are
passed on during cuddling in the first few days after birth.
They also tend to develop Demodectic mange, sign that their immune system can't handle the
mites that nearly all dogs have in their skin,
passed on to them
by their mother.
