Causes
The Otodectes cynotis mite, highly contagious through direct contact. Common in young animals and in group living situations.
Diagnosis
The vet examines the ear with an otoscope and/or identifies the mites under the microscope in a wax sample.
Treatment
Ear cleaning plus a specific antiparasitic (many modern antiparasitic spot-on treatments cover them). Treat all animals in contact.
Prevention
Regular external antiparasitic treatment (several cover ear mites). Check the ears of any new animals.
