Scabies in dogs is a severe pruritic skin disease. After mating with adult scabies mites, the female burrows in the skin of the dog and lays eggs in the hole. The eggs hatch within 3 to 8 days, and the larvae move to the skin surface to molt and develop into first stage nymphs, second stage nymphs and adults. Males and virgin females also burrowed inside the skin, but mating took place on the surface of the skin. The entire life cycle takes 10 to 14 days. Scabies Canis is infected through direct contact.
