Why does my dog keep shaking his head?

Has your dog been shaking her head lately, leaving you at a loss as to why? In this post, our Orange Park vets share what you should do if you notice your dog is shaking their head, when to go to your vet, and more. 

Why do dogs shake their heads?

If your dog keeps shaking their head, this might be perfectly normal behavior for your canine friend - if it only happens infrequently. 

Dogs may use headshaking as an effective way to expel irritants from their ears. 

When should I be concerned about my dog's head shaking?

If your dog shakes their head once or twice and then stops, there is probably nothing to worry about. However, if your dog is shaking their head frequently and vigorously, it's time to take them to the vet for an examination.

Common Reasons Dogs Shake Their Heads

Some of the most common reasons for head shaking in dogs can be easily treated by your veterinarian once diagnosed. That said, if left untreated, ear conditions can quickly develop into more serious problems. Common causes of head shaking include:

Yeast & Bacterial Infections in the Ear

The most common health problem that causes excessive head shaking in dogs is ear infection. These infections are itchy and cause a lot of inflammation and discharge, which causes a dog to shake her head. Examine your dog's ear flap for redness, discharge, or swelling. If this is the case, an infection is highly likely. Ear mite infestations can cause similar symptoms, but they are not as common as yeast or bacterial infections in dogs (particularly in adult dogs).

Remember that infections may happen deep in a dog's ear, so even if you don't see obvious signs of one an infection may still be present. 

Water in the Ears

This is easily avoided by inserting cotton balls (or half a cotton ball for small breeds) into your canine companion's ears before swimming or bathing. When bathing your dog, avoid dumping or spraying water directly on his head. Instead, bathe her from the neck down and use a damp washcloth to clean her ears and face.

If your dog won't tolerate cotton balls in her ears while swimming, consider cleaning the ears afterward with a drying solution. Based on your dog's specific needs, your veterinarian may be able to recommend a safe, effective product. Consider wearing an ear band as well.

Allergies Causing Itchiness in the Ear

Another frequent problem that causes dogs to shake their heads is allergies. A food allergy or environmental triggers (such as dust, pollen, storage mites, mold spores, etc.) could be affecting your dog. When a dog has allergies, they may exhibit a variety of signs, such as hair loss, itchy skin, recurrent ear and skin infections, head shaking, ear-scratching, face-rubbing, or foot-chewing.

A veterinarian will frequently recommend a diet for your dog that contains one carbohydrate (such as potato or rice) and one protein source that the dog has never had before (such as venison or duck) or that has been hydrolyzed (broken down into tiny, non-allergenic pieces). For a month or two, the dog must only consume this food. If symptoms significantly improve or go away completely, a food allergy is probably the cause.

Serious Conditions Associated with Head Shaking

Other health conditions that may cause dogs to shake their heads excessively include inflammatory diseases, foreign objects that get lodged in the ear canal, or neurologic disorders that lead to head tremors (sometimes easily confused with head shaking). 

If your dog has recurrent ear infections, the underlying cause needs to be diagnosed by your veterinarian. The cause may be anatomical abnormalities, hypothyroidism, allergies, or something else. 

For a dog's long-term health, determining the cause of head shaking is crucial because it may indicate a more serious issue. Additionally, it's essential because particularly ferocious or persistent head shaking may cause blood vessels inside a dog's ear flap to rupture. We should be preventing excessive head shaking, not just treating it when it develops, as the resulting aural hematomas frequently necessitate surgery to correct.

What to Do if Your Dog is Shaking Their Head

Head shaking can be caused by or lead to minor or severe health issues in dogs. 

It's key for your vet to diagnose the specific cause of your dog's head shaking early so the issue can be treated before it becomes a more serious problem.
