Demodex causes skin problems. The skin itches—mildly with localized infection and severely with generalized infection. Some pets scratch until they develop bacterial infections along with demodex infections. The hairs fall out and bald spots develop. Bald patches, especially around the eyes, mouth, elbows, and front legs are common. The skin may be rough and dry and is referred to as lichenoid.
Three forms of Mange Demodex
There are 3 forms of demodex and signs and symptoms depend upon which form the pet develops:
- localized,
- generalized, and
- limited to the feet (pododermatitis).
Localized Mange Demodex
Localized demodex occurs in only one area, such as on the ear or the face. A few spots in the local area may be affected. Usually the symptoms are mild and clear up on their own. About 10% of pets with localized demodex develop generalized demodex.

Generalized Mange Demodex
Generalized demodex occurs in multiple locations, such as ear, elbow, and stomach, and may progress to cover most of the body, including the feet. Generalized demodex occurs in young animals and in adults. When it occurs in an adult, it suggests the pet has a significant disease or health problem that predisposed it to develop widespread demodex infection. For example, pets with cancer, hypothyroid disease, allergies, and heartworm infections may develop demodex infections.
Pododermatitis
Demodex of the feet (podo = feet and dermatitis = inflammation of the skin or dermis) can be a localized infection or part of a generalized infection. Pododermatitis is common in dogs with bulldog genetics.

Demodex is a mite that lives in small numbers in the skin of healthy dogs and cats without causing a problem.
Unhealthy dogs and cats, especially those with immune problems, Cushing’s disease or on steroid medications can develop severe demodex infection.
Pets with severe demodex infections should not be bred because the disease has a genetic component.
Ivermectin, which can be used to treat demodex, causes severe illness in some herding dog breeds.
