Sarcoptic mange (Figure 1) of dogs is related to the human skin disease called scabies. Dog mange is caused by the canine mange
mite which frequently also attacks man. A closely related mite attacks cats and produces a severe mange in felines.

Red mange or demodectic mange (Figure 2) of dogs is caused by a mite which
lives in the hair follicles of the skin. The first evidence of red mange is the appearance of bald areas where hair has fallen out. As the bald area spreads,
itching and irritation increases. Bacterial infections are usually associated with red mange and produce a foul odor. Red mange usually weakens the animal
exposing it to other diseases which then kill the animal. Many animals will self cure. The disease is most common in dogs from 3 months to 1½ years old.
Stressed animals often exhibit mange symptoms. The most effective control is applied by veterinarians.

Ear mange is common among dogs, cats and rabbits. The mites do not burrow in the skin but live deep in the ear canal and feed on skin. The resulting
irritation causes the ear canal to become congested. The affected animal rubs its ears and shakes its head to relieve the itching. Ear mange may be treated
by applying mineral oil to the ear canal with a medicine dropper or cotton swab and by cleaning accumulations of foreign matter every other day for about 3
Proper care, good hygiene, and the maintenance of good health will increase a pet's resistance to skin disease. Canine mange mainly occurs on
young animals which are undernourished and suffering from internal parasites and mothered by infested animals. Pets should not be permitted to mingle with
mangy animals or contact premises occupied by them since individual contact is the most important method of transmission. In almost all cases of mange on
pets a veterinarian should be consulted.
