Underlying Causes for Dog Shaking Ears

Now that you know what implications ignoring shaking of ears in dogs, you are probably interested in knowing what causes this behavior. Explained below are some of the most common reasons for dog shaking ears:

Ear Infection

Ear infection is one of the most common reasons for ear shaking in dogs. Both bacteria and yeast infections can inflict a dog’s ears. Even a mild yeast infection is enough to cause frequent shaking of the ears.

Predisposing factors for dog ear infection include ear mites, wax buildup, excess hair growth in the ear canal, hypothyroidism, foreign objects such as grass awns, and allergies. Breeds with drooping ears such as springer spaniels, retrievers, and setters are also more prone to ear infections. Their longer ear flaps provide a dark – often moist – an environment that is suitable for yeast and bacterial growth.

In addition to your dog shaking ears, an ear infection is notable for the following signs and symptoms:

  • Scratching the ears
  • Reddened ear flaps
  • Swelling of the ear canal
  • An offensive odor from the ear
  • A discharge that is brown, yellow or blood-tinged
  • Tilting the head to one side
  • Hair loss in and around the ears
  • Loss of balance
  • The ear can also feel very hot to the touch.

Diagnosis and Treatment of Dog Ear Infection

If an ear infection is suspected, your veterinarian will start by examining the inside of the ear canal and eardrum with the help of special equipment. This may require the use of anesthesia to alleviate pain. This is usually followed by a cytology to analyze the debris inside the ear canal. Once the offending bacteria is ascertained, appropriate treatment is the given.

Thyroid function may also be tested if an underactive thyroid is suspected as an underlying cause for the ear infection.

Treatment typically involves professional cleaning and topical or oral medication.

Foreign Debris in the Ear Canal

If your dog keeps shaking his ear but there are no signs of ear infections, chances are that it has some foreign debris trapped in the ear. Unlike a human ear which is straight from the opening all the way to the eardrum, a dog’s ear is L-shaped. The first vertical part of the ear canal leading from the ear opening is preceded by a second horizontal section leading to the eardrum.

This ear structure makes dogs susceptible to having foreign debris and moisture trapped inside the vertical part of the ear. Springer Spaniels and other dog breeds with drooping ears tend to experience this problem more commonly.

Among the foreign debris that commonly gets lodged in dogs’ ear canal are grass seeds and foxtails. If you have reasons to suspect foxtails, get immediate help. Those pesky little things can travel inside your dog’s body and wreak a health havoc.

Ear Mites and Ticks

Ear mites are very irritating and can as well explain why you see your dog shaking ears at night or every now and then. These tiny parasites should be suspected in the following symptoms are observed:

  • Scratching of ears
  • Reddish brown or dark-brown, coffee-like discharge in the ear canal
  • You may be able to see tiny white specks moving inside the ears. These are ear mites themselves.
  • Foul odor in dog’ ears

Although ear mites are relatively uncommon in dogs as says, they can cause severe ear damage if left untreated. There are several over the counter remedies for ear mites. These are widely available in pet supplies stores and online. Of these anti-parasitic medications, Selamectin (available under names such as Revolution and Stronghold) is perhaps the most popular.

According to, pouring a few drops of mineral oil or essential oils such as neem oil can help.

For ear mite treatment, your veterinarian may as well clean your dog’s ears to eliminate any discharge as well as prescribe some antibiotics and/or anti-inflammatory medications.

A dog can also keep shaking the ears if a tick is attached to it.


Is your dog shaking ears frequently even though the ears are clean and there are no obvious signs of infection such as discharge? It could be a case of ear vasculitis. This is an inflammation of the blood vessels inside the ear flaps (pinna). It is seen more in some breeds of dogs including Dachshunds and Jack Russell terriers.

Fly bites, frostbite, and immune disorder are listed among the most common underlying factors for ear vasculitis in dogs. The condition typically begins with the thickening of the outer margins of the ear. This then leads to ulceration (formation of ulcers or wounds) and crusting. It is common for the crusts to break open and bleed as the dog keeps shaking the affected ears.

Ear Polyps

It is also common for a dog to keep shaking its ears if it has polyps or any other solid masses growing inside the ear canal.

Allergic Reactions

Allergic reactions can cause your dog to develop itchy ears and give an endless urge to shake or scratch the ears. This usually results from an exposure to allergens through inhalation or ingestion. Common dog allergens include pollen, cigarette smoke, mold spores, feathers, dander, perfumes, cleaning products, and rubber.

With inhalation or ingestion of these allergens, the dog’s immune system reacts by fighting the same through s series of reactions that culminate in various allergy symptoms including itchy ears and ear infections. Dogs can also be allergic to certain foods. Soy, wheat, and dairy products are some good examples.

If you see your dog shaking ears constantly, your best course of action is to have your veterinarian examine her. Your veterinarian will help you rule out ear infections and other serious ear problems and prescribe appropriate treatment.
