- Mites are the cause of mange, a condition that may affect dogs of all ages. Mange can occur anywhere on the dog's body and may be widespread. Dogs that have severe cases of mange may develop skin ulcers as a result of itching and scratching.
- A veterinarian may diagnose demodetic mange by taking a skin sample for examination. The veterinarian scrapes the skin in an affected area and examines it under a microscope. Demodetic mange may appear in one localized area of the dog's body, or it may spread to other areas of the body. Skin ulcers and sores are common with this form of mange. Skin sores may or may not itch with this form of mange and sores can have a yellow or green discharge.
- Sarcoptic mange is also known as scabies, and it is also caused by mites that enter the skin. These mites then leave toxins on the dog's skin which cause itching, redness and severe scratching. Dogs that suffer from this condition often scratch until sores on the skin develop. Sarcoptic mange usually appears as red sores all over the dog's body. Sarcoptic mange is contagious and can affect humans as well as dogs. According to Dog Health Guide, veterinarians usually treat this condition with a medicated dip.
- The symptoms associated with mange are crusting skin, oily skin and skin lesions. Dogs that suffer from mange may also have hair loss and sores that are scabbed over. Mange typically begins on the elbows and the ears, and can eventually spread to larger areas of the body.
- Demodetic or sarcoptic mange may be very persistent conditions in dogs. While the treatment for each type of mange are similar, sarcoptic mange is a very serious condition that can be fatal if left untreated. Mange may be a recurrent condition that requires ongoing treatment.
