The ear mite (Otodectes cynotis) is a surface mite that is usually found in the ear canal but it can live on the skin surface. Ear mites are contagious & pets become infested by direct contact with other pets. The mite is barely visible to the naked & may be seen as a white speck moving against a dark background.

It takes 3 weeks for a mite to develop from an egg to an adult. Adult ear mites live about 2 months, during which time they continually reproduce.

Ear mites are a common cause of ear infection & are the 2nd most common external parasite found on pets (2nd to the Flea)

Infestations are a common in puppies & kittens, although pets of any age can be affected.

Clinical signs/symptoms may include:

1. Ear irritation, leading to scratching at the ears/head shaking
2. A dark waxy or crusty discharge from the ear
3. Hair loss resulting from self-trauma caused by scratching or excessive grooming
4. A crusted rash around/in the ear.
5. An aural hematoma (a large blood blister on the ear, caused by rupture of small blood vessels between the skin cartilage) occurs due to the scratching at the ears.

Skin lesions most frequently affect the ear & surrounding skin but occasionally other areas of the body may be affected.

A diagnosis is made by observing the mite with an otoscope or by microscopic exam of ear swabs. Your vet will advise you about which treatments are suitable..

Ear mites may cause a temporary itchy rash on susceptible people if there are infested pets in the household, although this is considered to be a rare event. Eradication of the mites from the pets will cure the problem.
