Ear mites, scientifically known as otodectes cynotis, are mites of dogs and cats that can infest the outer ear and cause inflammation of the ear canal. Infestations can be mild, but in some cases, it can lead to infection and even ruptured eardrums if left untreated.

Ear mites are more common in cats than dogs. These microscopic parasites can result in the form of mange called otodectic mange, the symptoms of which can be similar to the symptoms of ear infections in dogs. Recognizing the signs of ear problems like mites will help with your dog’s treatment before the infestation leads to a painful condition like a ruptured eardrum.

Your dog most likely contracted ear mites through direct contact with another dog or cat, sharing grooming materials with an infected dog or cat, or sleeping near or on the same bedding as infected animals. Crowded, stressful circumstances like boarding facilities, dog daycares, grooming salons, and shelters may also increase the risk of transmission, as these circumstances can suppress your dog’s immune system.

The veterinarian will examine your dog’s ears with an otoscope to look for mites and signs of mites. Mites appear as white specks to the naked eye, and if your veterinarian suspects that mites are the cause of your dog’s symptoms, they will take a sample with an ear swab to identify under a microscope. In some cases, your veterinarian may also recommend additional diagnostic testing, such as bloodwork, to rule out the possibility of an underlying condition.

Veterinarians diagnose ear mites in dogs with a physical examination and by identifying suspected mites under a microscope.

Treating Your Dog for Ear Mites

Dogs are treated for ear mites with a anti-parasitic medication (in the form of ear drops), an oral medication, or a topical medication applied to the skin. It is important for owners to follow the instructions and administer the medication for the duration of the treatment, as this will ensure that the medication kills the mites throughout all stages of their lifecycle.

In most cases, your veterinarian will recommend treating both ears even if only one is affected. This will prevent the spread of the mites. Your veterinarian might also suggest an ear flush to clear out your dog’s ear canal, as this will decrease irritation and remove debris. Additional follow-up visits and multiple cleanings may also be recommended.

Flushing and cleaning can be painful for dogs. If your dog is sensitive or if the ear is painful, your veterinarian may sedate your dog during the office visit.

Recovery and Management of Ear Mites
