"Dog ear mites" is a common term that many pet parents are familiar with, but recognizing them is a different matter. Since many conditions can cause inflamed, itchy ears, it's important to recognize what makes this parasite unique, and how diagnosis and treatment differ from problems like ticks, fleas, and even allergies. Let's explore what ear mites are, how to identify them and how to help your dog get rid of these tiny parasites.

What Are Dog Ear Mites?

Ear mites are highly contagious, tiny parasites called Otodectes cynotis. This microscopic mite, which is technically considered part of the arachnid class, lives on the surface of the skin and ear canal and can just barely be seen by the naked eye, appearing as pin-prick-sized white dots.

Signs of Dog Ear Mites

Ear mites are extremely uncomfortable for dogs, which is something no pet parent wants their pet to experience. By knowing what to look out for, you may be able to expedite the diagnosis and prevent the infestation from getting worse. If you notice anything unusual about your dog's ears, it's always best to contact your veterinarian.

Common signs of ear mites in dogs include:

  • Extreme itchiness, especially around the ears, head or face
  • Scratching or rubbing ears
  • Wounds on scabs on the ears, head or face
  • Shaking head
  • Redness of the ear
  • Thick dark-brown to black debris in the ear canal

Ear Mites or Ear Infection?

 

Many of the signs that are common with ear mites are also seen with other ear conditions, such as a yeast or bacterial infection. So how can you tell the difference? Ultimately, the best way is to have your vet provide an accurate diagnosis. However, there are some differences that may indicate one or the other.

Yeast infections may include more greasy, yellow discharge, as well as a pungent odor (many pet parents liken the smell to corn chips). Bacterial infections may have a rotten-smelling, yellow to green ear discharge. In some rare instances, all three organisms (ear mites, yeast and bacteria) could be present in the ear. In these dogs, the yeast and bacterial infections usually develop secondary to the inflammation and debris in the ear from dog ear mites, creating a prime environment for yeast and bacterial overgrowth.

Causes of Dog Ear Mites

Ear mites occur most commonly in young animals and are transmitted by direct physical contact with other infested animals. This could be another dog or cat in the home, from social activities outside the home, or in some cases, from close contact with infested wildlife, like foxes. Since ear mites are highly contagious among dogs and cats, all animals in the home should be treated (at the direction of your vet), even if they are not showing overt symptoms.

How Are Ear Mites Diagnosed?

Your vet will be able to diagnose ear mites by doing an otoscopic ear exam. This allows them to look deeper inside the ear. They will also typically look at a sample of the ear discharge under a microscope to confirm the reason for your dog's discomfort.

Because signs of ear mites are so similar to other conditions in dogs, it's important to receive an accurate diagnosis from your vet, rather than trying to treat it at home based on signs alone.

Ear Mite Treatment for Dogs

There are many treatment options for dog ear mites, including medications that can be applied directly in the ears, as well as others that are injected, taken orally or topically to the skin. Fortunately, many of these prescribed medications can eradicate dog ear mite infestations with just one application. The bonus? These medications are commonly utilized as routine flea and tick control too, so you get the added benefit of prevention from other common parasites.

A thorough ear cleaning is still necessary to remove the wax and debris from the ear at the start of treatment. In some cases, your dog may need an additional ear cleaning about one month after receiving the treatment to remove any remaining debris.

And remember: all animals in the home should be treated under the guidance of your vet, even if they are asymptomatic.
