Why Does My Dog Keep Shaking Their Head? When to Worry
- Aug 10
- 9 min read
A dog giving their head an occasional shake is completely normal. They may have just woken up, finished playing, come in from the rain or simply be readjusting their ears.
But when head shaking becomes frequent, forceful or is accompanied by scratching, redness, smell, wax or pain, your dog may be telling you that something is irritating their ears.
Repeated head shaking is one of the most common signs of an ear or skin problem in dogs, with possible causes including allergies, ear infections, ear mites, foreign bodies and inflammation.
Dark brown, crumbly ‘coffee-ground’ debris is commonly associated with ear mites, although yeast or bacterial ear problems can look similar, so veterinary examination is needed to confirm the cause.”
Quick Answer: Why Does My Dog Keep Shaking Their Head?
Common reasons include:
An itchy or irritated ear
Ear infection
Allergies
Ear mites
Excess wax
Water trapped after swimming or bathing
Something stuck inside the ear
Damage or irritation to the ear flap
An aural haematoma
Less commonly, a deeper middle or inner-ear problem
If the shaking happens once or twice and stops, it may be nothing to worry about.
If your dog keeps doing it, scratches repeatedly or seems uncomfortable, the ears should be checked.
Is Occasional Head Shaking Normal?
Yes.
Dogs naturally shake their heads from time to time.
You might notice it:
After waking up
After scratching an ear
After bathing
After swimming
After running through wet grass
After vigorous play
The important difference is frequency and intensity.
One quick shake followed by completely normal behaviour is very different from a dog violently shaking their head every few minutes.
PDSA advises contacting your vet when head shaking or ear scratching becomes more regular than usual because repeated behaviour can indicate an underlying ear or skin problem.
What Causes Dogs to Keep Shaking Their Head?
There isn't one single cause.
Head shaking is a symptom, rather than a diagnosis.
The dog is generally trying to relieve an uncomfortable sensation somewhere around the ear, face or head.
1. Ear Infections
Ear infections are one of the most important causes to consider.
Dogs can develop inflammation and overgrowth of yeast or bacteria within the ear canal. Often there is another underlying problem that allowed the ear environment to change in the first place.
Signs can include:
Repeated head shaking
Ear scratching
Redness
Heat
Swelling
Pain
Unusual discharge
Excess wax
An unpleasant smell
Rubbing the side of the head against furniture or the floor
Some dogs become reluctant to let you touch the affected ear.
A smelly, painful or discharging ear needs veterinary assessment rather than simply being cleaned repeatedly at home.
2. Allergies
Sometimes the problem isn't primarily the ear at all.
Allergic skin disease is a common underlying cause of recurring ear problems in dogs. Skin lines the ear canal, so inflammation affecting the skin elsewhere can also affect the ears.
You may notice your dog also:
Licks their paws
Chews between their toes
Rubs their face
Scratches their body
Develops red skin
Suffers repeated ear problems
A dog whose ear problems repeatedly improve and then return may need the underlying trigger investigated, rather than simply another round of ear cleaning.
3. Ear Mites
Ear mites are tiny parasites capable of producing significant irritation.
They can lead to:
Intense scratching
Head shaking
Dark ear debris
Irritated skin
Secondary inflammation
However, dark wax does not automatically mean ear mites. Yeast, bacteria and mixed ear problems can produce similar-looking debris, which is why diagnosis sometimes requires examination of material from the ear under a microscope.
4. Something Stuck in the Ear
A foreign object inside the ear can cause sudden and very persistent head shaking.
This may happen after your dog has been:
Running through long grass
Walking through woodland
Playing outdoors
Exploring vegetation
A grass seed or other small foreign object can work its way into the ear canal.
A classic pattern is a dog that was perfectly comfortable and then suddenly starts violently shaking one side of their head after a walk.
Foreign bodies are a recognised cause of otitis and head shaking and may need to be removed using an otoscope, sometimes under sedation if the ear is painful or the object is deep.
Don't push tweezers or cotton buds into the ear trying to find it.
5. Water After Swimming or Bathing
Some dogs shake their heads immediately after swimming or bathing simply because water has entered or collected around the ears.
A brief shake afterwards isn't unusual.
But persistent irritation shouldn't simply be blamed on water.
Moisture within an ear that is already prone to inflammation can contribute to an environment in which ear problems develop.
If the head shaking continues, particularly with redness, smell, discharge or soreness, arrange a veterinary check.
6. Excess Ear Wax
A small amount of normal wax isn't necessarily a problem.
However, excessive wax can occur alongside:
Allergies
Ear inflammation
Ear infection
Ear mites
Narrow ear canals
PDSA notes that excessive earwax can be one of the underlying factors associated with ear infections.
Repeatedly cleaning wax away without establishing why it is being produced can allow the underlying problem to continue.
My Dog Keeps Shaking Their Head but Their Ears Look Clean
This is a surprisingly common situation.
An ear can look perfectly normal from the outside while the problem is deeper inside the canal.
A dog's ear canal doesn't travel straight towards the eardrum like a simple tube. Much of it cannot be seen without an otoscope.
Possible causes can therefore include:
Early inflammation
Allergy-related irritation
A deep foreign body
Wax further down the canal
Middle-ear disease
Pain around the ear rather than visible disease on the ear flap
So “I can't see anything” doesn't always mean there's nothing there.
A vet can examine much deeper into the canal using an otoscope.
Why Is My Dog Scratching Their Ear and Shaking Their Head?
When scratching and head shaking occur together, irritation becomes much more likely.
Common causes include:
Ear infection
Often accompanied by smell, redness, wax or discharge.
Allergic skin disease
Particularly if your dog also scratches elsewhere or licks their paws.
Ear mites
Often intensely itchy.
Foreign body
Particularly when symptoms began very suddenly.
Inflamed or injured skin
The irritation may involve the ear flap as well as the canal.
PDSA lists allergies, infections, fleas, ear mites, foreign bodies, injury, ear lumps and aural haematomas among recognised causes of repeated scratching and head shaking.
Can Head Shaking Cause a Swollen Ear?
Yes.
Repeated vigorous head shaking can occasionally cause blood vessels within the ear flap to rupture.
Blood then accumulates between the tissues, creating an aural haematoma.
The ear flap may suddenly look:
Puffy
Thick
Heavy
Balloon-like
Soft or fluid-filled
The underlying cause of the shaking—such as itchy skin, infection or mites—also needs addressing.
A swollen ear flap should be examined by a vet.
Which Dogs Are More Prone to Ear Problems?
Any dog can develop ear disease.
However, anatomy, excess hair in the canal and a tendency towards skin disease can increase risk.
PDSA lists breeds including:
Cocker Spaniels
English Springer Spaniels
Cavalier King Charles Spaniels
Bichon Frise
Maltese
French Bulldogs
Pugs
Shar Pei
Newfoundlands
among dogs with an increased tendency towards ear problems.
This doesn't mean every dog of these breeds will have bad ears.
It simply means owners may need to pay particular attention to early changes in smell, wax, redness, scratching and head shaking.
Why Does My Dog Shake Their Head After Sleeping?
One or two shakes after waking can simply be normal behaviour.
Dogs may shake their:
Head
Ears
Neck
Whole body
as they stretch and become active again.
But if every waking period triggers prolonged scratching or repeated head shaking, there may already be irritation present.
Look for other changes rather than judging the shake in isolation.
Head Shaking or Head Tremor — What's the Difference?
These are not the same thing.
A head shake is deliberate. The dog actively moves their head from side to side, usually because something feels itchy, irritating or painful.
A head tremor is an involuntary movement the dog cannot simply choose to stop.
PDSA advises veterinary attention for a head tremor because neurological or inner-ear problems can sometimes be responsible.
If you're unsure which you're seeing, filming an episode on your phone can be extremely useful for your vet.
When Should I Worry About My Dog Shaking Their Head?
Book a veterinary appointment if the shaking is:
Happening repeatedly
Becoming more intense
Lasting for several days
Accompanied by scratching
Associated with redness or swelling
Painful
Accompanied by discharge
Associated with a bad smell
Causing sores or bleeding
Affecting only one ear very suddenly
Repeatedly returning after treatment
Ear disease can be painful, and treating it earlier is generally easier than waiting until inflammation becomes severe.
More Serious Warning Signs
A problem involving the middle or inner ear can affect balance as well as hearing.
Seek prompt veterinary attention if you notice:
Head tilt
Loss of balance
Stumbling
Circling
Abnormal flickering eye movements
Vomiting alongside balance problems
Facial weakness
Severe pain
Sudden hearing problems
PDSA recommends a same-day veterinary appointment when head tilt or loss of balance accompanies suspected ear disease because these can indicate a deeper ear problem.
What Should I Do If My Dog Keeps Shaking Their Head?
Start by looking at the visible part of the ear without inserting anything into the canal.
Check for:
Redness
Swelling
Excess wax
Discharge
Blood
Crusting
Unusual smell
Obvious injury
Swelling of the ear flap
If the dog appears painful or the ear looks abnormal, arrange a veterinary examination.
Don't Use Cotton Buds Inside Your Dog's Ear
Avoid pushing cotton buds into the ear canal.
They can push debris further into the ear and risk damaging delicate structures.
PDSA recommends cotton wool rather than cotton buds when ear cleaning has been advised.
Should I Clean My Dog's Ears When They Keep Shaking Their Head?
Not automatically.
If the ear is very red, painful, swollen, smelly or producing unusual discharge, it is better to have the cause established first.
Cleaning immediately can sometimes:
Make a painful ear more uncomfortable
Remove material your vet could have sampled
Push debris deeper
Mask what the original problem looked like
PDSA advises having sore or abnormal ears properly checked before buying or using over-the-counter treatment because temporary improvement does not necessarily resolve the underlying cause.

Important Ear-Care Advice
An ear-care product should not replace veterinary diagnosis when your dog:
Has significant pain
Has a strong or unusual smell
Has pus, blood or heavy discharge
Suddenly starts violently shaking one ear
May have a grass seed or foreign body
Has a swollen ear flap
Develops head tilt or loss of balance
Has recurring ear problems
These signs can have several different causes, and the correct treatment depends on what is actually happening inside the ear. Veterinary examination may include an otoscope examination and microscopic assessment of ear material.
Always follow the current product instructions and seek veterinary advice if you are unsure whether an ear-care product is appropriate for your dog.
Why Do My Dog's Ear Problems Keep Coming Back?
Recurring ear problems deserve further investigation.
Repeated infections may be associated with an underlying issue such as:
Allergic skin disease
Ear anatomy
Excessive wax production
Persistent yeast or bacterial imbalance
Ear mites
Growths
Chronic inflammation
Middle-ear disease
Merck Veterinary Manual notes that identifying and addressing the underlying cause is important because ear inflammation often returns when contributing factors remain untreated.
Simply treating the visible wax every few weeks may therefore not be enough.
Can You Prevent Head Shaking?
Not every ear problem can be prevented, but sensible ear care can help you notice changes early.
Check Your Dog's Ears Regularly
Get used to what normal looks and smells like for your dog.
That makes it much easier to spot:
New redness
More wax than usual
An unusual smell
Swelling
Discharge
Increased scratching
Keep Ears Dry After Swimming
Gently dry the visible outer ear after swimming or bathing.
Manage Underlying Allergies
Repeated ear problems may be part of a wider skin condition.
Don't Over-Clean
More cleaning is not necessarily better.
Excessive cleaning can itself irritate the ear canal, and PDSA lists excessive cleaning among possible underlying contributors to ear infections.
Deal With Problems Early
A mildly irritated ear can become much more uncomfortable if left untreated.
The Bottom Line
An occasional head shake is usually nothing unusual.
But repeated head shaking is your dog's way of telling you that something doesn't feel right.
Common causes include:
Ear infection
Allergies
Ear mites
Excess wax
Foreign bodies
Skin irritation
The safest approach is to look at the whole picture.
A dog that shakes once after waking but is otherwise comfortable is very different from a dog repeatedly shaking, scratching and producing smelly discharge.
And remember: an ear can look clean on the outside while there is still a problem deeper inside.
> Persistent head shaking deserves attention—because finding the cause early can prevent a small irritation becoming a painful ear problem.
