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.
