A highly contagious parasitic skin disease of dogs, cats, and rabbits. In a multiple-pet household, more than one animal is usually affected.

Pruritius may be mild to severe. Papular, crusting eruptions (cats) or scabies-like lesions (dogs) are present. Other adult pets (dogs, cats, rabbits) in the household may be asymptomatic carriers.
