Is It Normal for Dogs to Shake Their Head?

An occasional head shake is completely normal.

Dogs may shake their head after waking up, playing, rolling around outside or getting wet. It’s a natural way of getting comfortable.

What deserves more attention is repeated head shaking throughout the day.

If your dog regularly stops what they’re doing to shake their head, scratch their ears or rub their face against the floor or furniture, it’s worth checking their ears more closely.

1. Excess Ear Wax

Ear wax has a useful job. It helps trap dust, pollen and other debris before it travels further into the ear canal.

Problems can develop when too much wax accumulates.

You may notice:

• Brown wax
• Sticky debris
• A mild smell
• Head shaking
• Scratching around the ears

Dogs with floppy ears can be particularly prone to wax build-up because less air circulates around the ear canal.

2. Seasonal Allergies

Spring and summer can be particularly troublesome for dogs with sensitive ears.

Grass pollen, tree pollen and weeds can all trigger irritation, and dogs often show environmental allergies through their skin rather than with the sneezing and watery eyes we associate with human hay fever.

If your dog is also:

• Chewing their paws
• Licking their legs
• Scratching their tummy
• Rubbing their face

allergies could be contributing to their ear irritation.

3. Ear Infections

Dogs naturally have microorganisms such as bacteria and yeast living on their skin.

If the ear becomes warm, damp or inflamed, the normal balance can change and an infection may develop.

Signs to look out for include:

• A strong or unusual smell
• Dark discharge
• Redness
• Pain when the ear is touched
• Persistent head shaking

If you notice these signs, arrange a veterinary examination rather than relying on home cleaning alone.

4. Swimming

Plenty of dogs love swimming, but moisture left behind in the ears can cause irritation.

Dogs with floppy ears may be particularly susceptible because their ear canals can remain warm and damp for longer.

After swimming, gently dry the visible outer ear with a clean towel.

Never push anything into the ear canal.

5. Grass Seeds

Grass seeds are a common problem during late spring and summer and can occasionally work their way inside a dog’s ear canal.

Typical signs include:

• Sudden, vigorous head shaking
• Holding one ear lower than the other
• Pawing at one ear
• Symptoms beginning immediately after a walk

If you suspect a grass seed has entered your dog’s ear, contact your vet. Trying to remove something from deep inside the ear yourself can push it further in or cause injury.

6. Ear Mites

Ear mites are less common than some other causes of ear irritation but can cause significant itching.

Signs can include:

• Persistent scratching
• Very dark or coffee-ground-like debris
• Frequent head shaking

Your vet can examine the ear and recommend appropriate treatment if mites are present.

7. Foreign Objects

Tiny pieces of vegetation, insects and other debris can occasionally become trapped inside the ear.

If your dog suddenly starts shaking their head and it doesn’t settle, particularly if only one ear seems affected, it’s worth having the ear examined.

8. Injury

Scratches, rough play or repeated vigorous head shaking can sometimes injure the ear.

Continued head shaking can also contribute to swelling of the ear flap.

If your dog’s ear suddenly becomes swollen, painful or noticeably different in appearance, seek veterinary advice.

When Should I Be Worried?

Arrange a veterinary appointment if your dog has:

• A strong or unpleasant smell from the ear
• Thick brown, yellow or green discharge
• Bleeding
• Significant pain
• A head tilt
• Loss of balance
• Sudden severe symptoms after walking through long grass

Repeated head shaking is a symptom rather than a diagnosis, so persistent problems are worth investigating.

How Can I Help My Dog at Home?

For mild ear irritation, simple everyday care can help:

• Check your dog’s ears after walks
• Dry the outer ears after swimming
• Remove loose grass and debris from around the ear flap
• Avoid putting cotton buds into the ear canal
• Keep the hair around the ears tidy where appropriate

Avoid repeatedly cleaning an ear that looks red, painful or inflamed.

A Natural Option for Mild Ear Irritation

If your dog’s head shaking appears to be associated with mild irritation or excess wax, Ear Stuff can form part of their regular ear-care routine.

Made with 100% natural cold-pressed plant seed oils, Ear Stuff is designed to help soften accumulated wax while gently conditioning sensitive ears, without alcohol or harsh cleansing ingredients.

Apply a small amount according to the product directions, gently massage around the base of the ear and allow the oil to spread naturally.

If itchy ears form part of a wider pattern of skin sensitivity, Food Stuff can also be used as part of your dog’s everyday skin and coat routine.

Frequently Asked Questions

Why is my dog shaking their head when their ears look clean?

Not every cause of ear irritation is immediately visible. Allergies, trapped moisture or irritation deeper inside the ear canal can cause head shaking before you can see obvious changes.

Why does my dog shake their head after a walk?

Pollen, grass seeds and small pieces of vegetation or debris can all irritate the ears, particularly during spring and summer.

Can swimming cause dogs to shake their heads?

Yes. Water left inside or around the ear can cause irritation, especially in dogs with floppy ears.

Should I clean my dog’s ears every week?

Not necessarily. Healthy ears often need very little cleaning, and cleaning too frequently can itself cause irritation.

Can allergies make dogs shake their heads?

Yes. Environmental allergies can contribute to itchy, irritated ears and repeated head shaking, particularly during certain times of year. Stinky Stuff
