There are several different mites that can affect dogs. One of the most common is known as demodex. It is a normal mite that lives in the hair follicles of dogs. Many dogs receive them from their mother. They are only typically a problem if the mites become overgrown for some reason. This is common in certain breeds of puppies (English bulldogs and pitbulls for example) or in adult dogs with an underlying illness. Affected dogs will have patchy spots of hair loss. They are not typically itchy. Another mite is sarcoptes. It is commonly spread through exposure to wild animals. This mite can be spread from dogs to people. This makes the dog extremely itchy. They will lose hair, have red skin and sometimes open wounds from the constant scratching. I hope this information helps you!

    Dogs get two types of mites, sarcoptic and demodex. Demodex is a normal mite of the skin and usually only causes a problem in young dogs with an immature immune system. Sarcoptic mange is a contagious mite that dogs obtain when exposed to an animal that in affected. Mites are not usually life threatening and can be treated with medications. Mites are diagnosed by a skin scraping and finding the mites using a microscope. If you think your dog have mites, he should be examined by a veterinarian to diagnose and treat the problem.
