Symptoms To Watch For In Your Dog: Excessive Head Shaking

by Jana Rade

You might have noticed that when talking about symptoms, sometimes a qualifying word is included, such as excessive panting, excessive drinking, excessive head shaking. That is because these are normal behaviors and whether or not there is a problem is a question of degree.


Dogs will shake their heads in response to any irritation, such as pain, an itch, a tickle or a bug bite.

If your dog is shaking their head persistently, you need to pay attention and look for a cause.

On our summer walks, JD will shake his head quite often, to fend off bugs. Deer flies in particular seem to like him. I think they know they can drive him nuts. Jasmine was much less concerned about them, she was a bush dog at heart. It was me who was following her around and chasing them off. She didn't seem to care.

The other day, on the way from the farm, JD kept shaking his head.

This was cause for concern and we were going to check his ears when we got home. He kept shaking and shaking ... and then we saw an ant waltz out of his ear. There was our culprit. The shaking stopped.

When an especially mean stray tick got on Jasmine's ear, her instinct was to shake her head. 

(Stray tick because it was one of the only two we ever found at the ranch.)

The bite was painful for Jasmine though, so every time she started to shake her head she'd cry a little, stop and hold her head down, tilted towards the affected ear.

This immediately alerted us to a problem and we found and removed the invader.

When your dog starts shaking their head like that, examine the ears, eyes, head, neck and skin carefully. Pay particularly close attention to the ears.

Some culprits are obvious and easy to deal with. Some require attention of your veterinarian.

A common cause of head shaking is otitis, inflammation of the ear canal. Grass awns, ear mites and other things might be at play but, allergies are also very common causes of ear inflammation.

An inflamed ear makes a great playground for bacteria or yeast. Infection often follows.

If there is redness, swelling, discharge or bad odor to the ears, it's time to see your veterinarian. If pain is involved, see your veterinarian right away. If you have a reason to suspect a foxtail, also don't delay. Those nasty little things can travel throughout your dog's body and cause serious damage.

Some breeds are also susceptible to ear vasculitis, which is inflammation of the blood vessels in the ear flap.

This condition typically comes with thickening of the ear margins, which eventually ulcerate and crust over.

Dogs with balance issues, be it from trauma, stroke, inner ear infection or vestibular syndrome, might shake their heads in an attempt to relieve their symptoms.

Not only is excessive head shaking a symptom of a problem, it can actually be a cause for one as well.

Sometimes a dog can shake their head so much that it will cause the blood vessels in the ear flap to rupture, resulting in a hematoma.

This will look like a swelling of the ear flap. It really is a pocket of blood and it will cause your dog to shake their head even more. Ear hematomas require veterinary attention if they are to heal without permanent disfigurement.

All this refers to voluntary head shaking.

This is what we typically picture as a head shake. There are such  things as involuntary head tremors, which are another story all together.

  1. I just wanted to say I love your blog, and your posts. They are so informative. Head shaking was the first indicator when my big boy had horrible ear infection.

  2. My dog stormy is a border collie and she is 3 months old. We keep her outside mostly all the day but we pay bunches of attention on her. Today I went outside and she was very happy but I could tell she was shaking her head just a little bit constantly. I'm not sure which reason that u provided for me is the answer to my dogs problem. I am scared for her becuase she is a puppy

    1. Well, could be any of the reasons, most likely a bite (are there bugs outside now?) or a foreign body or something. If it hasn't stopped yet, please talk to a vet.

    1. With or without the presence of visible wounds I'd definitely see a vet after such event. You never know what damage might have been done which isn't readily visible. There can be no visible wound or just a tiny one and yet there can be a lot of damage under the surface. Particularly with two big dogs having their way with one little one.

      Do not delay and see a vet.

  4. I have a 1 year old chihuahua that shakes her head quite a lot then she stops for a couple days and then it starts again. I've had her ears cleaned and was told told there is nothing wrong but the shaking continues. Could it be a habit she enjoys?

    1. You were told by a vet nothing is wrong? I assume they mean ear infection? What area do you live it? Any chance of grass awns and such things? I don't feel that such head-shaking would be an enjoyable habit. I believe there is a reason for it, just have to find it.

    2. She is strictly indoors, even when we take walks I have her in a stroller. We have coyotes and even a hawk that hangout in our area and since she's small I take extra precautions. She doesn't seem to be in pain. and except for head shaking she seems fine. I'm totally confused

    3. Well, things like ear infections are not an outdoors issue. Foreign bodies are less likely if not playing outside. But SOMETHING is up.

  5. I've had her ears rechecked. They are clean and clear. The vet is baffled because he says there is nothing wrong with her ears. Her shaking isn't as often. Thanks for your input

    1. That is strange. Infection or foreign body are the most common causes. Something is causing it, though. Any particular time of the day or circumstances under which it happens?
