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!
