Contagious skin diseases caused by mites on dogs are collectively called mange. Since mites and other parasites live on the skin of dogs, dogs are very prone to developing skin problems. Mange on dogs is a very common skin condition that's caused by dog worms or other parasitic mites that hide in their hair follicles or skin. The main symptom of mange is typically itching. Mange can be quite severe and contagious. Sarcoptic mange and demoex mange are the two most common types of mange. Sarcoptic mange, also known as scabies, is the more contagious of the two. If your dog isn't treated, the condition can worsen and lead to scaling and scabbing of the skin [source: Rappaport]. You can take your dog to the veterinarian for professional care, or you can try treating the more common sarcoptic mange with the home remedies below.
