What Are Ear Mites in Dogs? And How Do You Get Rid of Them?

Kittens are the most frequent target of ear mites, but our canine friends are certainly not immune. Ear mites are highly contagious between cats, dogs, and ferrets. That said, our pets get ear mites by coming into contact with other animals who have ear mites.

Kittens, puppies, and pets with compromised immune systems are often at higher risk for developing ear mite infestations compared to adult pets with mature and healthy immune systems.

Pet parents will often first notice that a dog with ear mites exhibits the following two symptoms:

• Shaking their head
• Scratching their ears and head
  
  

Other signs a dog has ear mites include:

• Discharge around the ears that resembles coffee grounds
• Red and swollen skin in and around the ears
• Hot spots/open sores (from all that scratching)

Keep in mind that the symptoms of ear mites in dogs are similar to those seen with other, more common ear problems, like yeast and bacterial ear infections. It’s important to see your veterinarian if you suspect your dog has any sort of ear infection so you can get a proper diagnosis and treatment plan.

Ear mites are barely visible to the naked eye. You can increase your chances of finding them by taking a chunk of debris from your dog’s ear, placing it on a dark, well-lit surface, and looking at it with a magnifying glass or taking a video that you can enlarge. Under these conditions, ear mites will look like tiny, white moving specks.

What do dog ear mites look like under higher magnification? Think fat ticks with short legs. Veterinarians can easily see them using a microscope or otoscope. (Otoscopes are those handheld devices that doctors use to look into the ears, kind of like little flashlights—you’ve probably seen them at your own doctor’s visits).

The safest, simplest, and most effective dog ear mite treatments are available through your veterinarian. First, your vet will confirm that ear mites are actually the cause of your dog’s symptoms. They’ll do this by examining your dog’s ear canals with an otoscope. They may also look at a sample of ear debris under the microscope. Then, your vet will discuss treatment options with you.

Treatment options may include:

• A thorough cleaning at the vet
• Prescription ear drops and medications such as Revolution, Advantage Multi, Simparica, and Bravecto
• Ivermectin injections

Your vet may be able to thoroughly clean your dog’s ears and perform all of the necessary treatments in just a single visit, though sometimes they may send you home with a prescription.

Treating ear mites at home with over-the-counter ear drops might also be an option for less severe cases. You’ll want to look for “pyrethrins” as an active ingredient and closely follow the label directions. One example is ADAMS Medication for Ear Mites for Dogs & Cats, which contains relatively low, but still effective, concentrations of pyrethrins and piperonyl butoxide.

(Keep in mind that some dogs are more sensitive to pyrethrins and might have a slight skin reaction. Also, some pyrethrin-containing products should not be used on dogs under 12 weeks of age.)

Tresaderm Topical Solution for Dogs & Cats is another option, but the drops must be put in a dog’s ears twice daily for two to three weeks, making it a much more labor-intensive option.

For both, dosing instructions based on a pet’s weight are printed on the product packaging. Always follow the label directions of whatever product you purchase and talk to your veterinarian if you have questions about the way your pet is reacting to a medication.

In addition to ear drops, you’ll also need to clean out your dog’s ears every few days until no more debris is present. (Psst. You can get the how-to here.) If at-home treatment isn’t successful, make an appointment with your veterinarian.

Mites are highly contagious among dogs, cats and ferrets. For that reason, all susceptible animals in your home must be treated. Pets without symptoms can often just be given a topical parasite preventive containing an active ingredient like selamectin, moxidectin, fluralaner, afoxolaner or saralaner. Products containing these active ingredients require a prescription from your veterinarian. It’s also good practice to routinely wash your pets’ toys and bedding with soap and hot water.

The easiest way to prevent ear mites is to routinely give your dog a flea preventive that also works against ear mites. Revolution (selamectin) is available for use against ear mites, but medications with other active ingredients such as moxidectin, fluralaner and afoxolaner can be prescribed by veterinarians, as well. Many of these products prevent multiple types of parasites, such as fleas, roundworms, and hookworms.

Not sure what you’re looking for? Your veterinarian can help you pick the best option based on your dog’s risk factors. It’s also a good idea to meet with your veterinarian if you want to discuss your overall parasite prevention strategy. With appropriate treatment, your canine companion should soon be feeling better.
