The diagnosis of scabies is made by skin scrapings or a skin biopsy of the patches of baldness. It cannot be made simply by observation, because it resembles other skin conditions like ringworm, demodectic mange, and allergies, which require different treatment. The treatment consists of weekly injections of Ivermectin for up to four weeks. However, Collies, Shetland Sheepdogs, Old English Sheepdogs, and other herding breeds do not tolerate Ivermectin. For these dogs, multiple dips in the insecticides Lyme Sulfur or Paramite are recommended after clipping the affected areas.
Dandruff shampoos can also help.
Cortisone relieves the itching. Infected sores can be treated with topical antibiotics. Because sarcoptic mange is so contagious, all household pets must be treated, whether they are symptomatic or not. In addition, proper nutrition and exercise are important in fighting this condition. It is caused by a large red mite that is often found in kennels, and it is highly contagious.
