What is leishmaniasis?

Canine leishmaniasis is a potentially fatal disease caused by a microscopic parasite. Dogs can become infected when bitten by an infected sand fly. Sand flies, in turn, can become infected by biting an already-infected animal.

Signs of canine leishmaniasis include dry skin, dandruff, hair loss around the eyes and muzzle, and skin sores, especially on the dog's head and legs. Weight loss can be severe.

Canine leishmaniasis was recently discovered in hunting packs of Fox Hounds in the Southeastern United States. In areas with infected sand flies, dogs should wear collars impregnated with insecticide, and should stay indoors when sand flies are most active – from just before sunset until sunup.
