Skin diseases can be one of the most difficult problems to deal with. There are a number of things that can cause problems and sometimes finding the root of the problem can be difficult. In our environment, fleas/mites and allergies are the most common causes. In the case of fleas, the parasite can often be seen on the animal. There are several treatment/control options if this is the problem and the best one will depend on the environment and the pet.
A number of diagnostic tests may need to be performed before the cause of the skin disease is found. Such tests include, skin and hair cultures, skin scrapings for mites or cytology, biopsies, and blood tests. With any skin problem, good nutrition and grooming often help prevent the disease or may reduce the symptoms.
