Also, there are two types of
mange. One form is not contagious (demodectic) to other animals
or people, and the other form is (sarcoptic). Sarcoptic, or canine scabies, is highly contagious. It's a burrowing mite that gets into the skin. Demodectic mange is a mite that is on all dogs, but some dogs are more succeptable to becoming a host, usually due to an immune system problem, high stress, or malnutrition. If either type of mange goes untreated, it can lead to severe skin infection.
