Head shaking in a Cocker Spaniel is never random. While the occasional shake is normal, repeated or forceful head shaking is your dog’s way of telling you that something is irritating, painful, or uncomfortable—most often inside the ears. Because Cocker Spaniels are particularly prone to ear and skin issues, persistent head shaking should always be taken seriously.
This article explains why Cocker Spaniels shake their heads, how to identify the underlying cause, and what you can do to stop it.

Occasional vs Persistent Head Shaking
Before looking at causes, it helps to separate normal behaviour from a problem.
Normal head shaking:
- Happens after waking up
- Occurs after getting wet
- Is brief and infrequent
Problem head shaking:
- Happens many times a day
- Is forceful or violent
- Is paired with ear scratching or rubbing
- Gets worse over time
If your Cocker Spaniel is shaking his head repeatedly, there is almost always an underlying issue that needs addressing.
The Most Common Cause: Ear Infections
Why Ear Infections Trigger Head Shaking
Head shaking is the body’s attempt to relieve irritation inside the ear canal. In Cocker Spaniels, ear infections are the number one reason for repeated head shaking.
Infections cause:
- Inflammation
- Pressure and discomfort
- Itching or burning sensations
- Pain when the ear moves
Shaking the head temporarily relieves pressure, but it does not fix the problem.
Signs of an Ear Infection
Alongside head shaking, you may notice:
- Scratching at one or both ears
- Redness inside the ear
- Thick brown, yellow, or black discharge
- Strong yeasty or unpleasant smell
- Pain when touching the ear
- Head tilt to one side
Cocker Spaniels often hide pain well, so head shaking may be the first obvious sign.
Yeast Overgrowth (Very Common in Cockers)
Yeast infections are particularly common in this breed.
Why?
- Warm, moist ears
- Poor airflow
- High wax production
Yeast causes intense itching rather than sharp pain, which often leads to constant head shaking and scratching, especially at night.
A strong, musty or “cheesy” smell is a key indicator.
Allergies: A Major Underlying Cause
Many Cocker Spaniels shake their heads because of allergy-related ear inflammation, even when there is no obvious infection yet.
How Allergies Affect the Ears
Allergies cause:
- Chronic inflammation of the ear canal
- Increased wax production
- Weakened skin barrier
This makes the ears itchy and uncomfortable, leading to repeated head shaking.
Common triggers include:
- Food ingredients (chicken, beef, wheat, dairy)
- Environmental allergens (grass, pollen, dust mites)
- Seasonal changes
If head shaking comes and goes or worsens at certain times of year, allergies are very likely involved.
Foreign Objects in the Ear
Cocker Spaniels love fields, long grass, and woodland—exactly where grass seeds and debris are found.
A foreign object in the ear can cause:
- Sudden, violent head shaking
- Head tilting
- Pawing at one ear only
This often starts very suddenly after a walk.
Do not attempt to remove objects deep in the ear, as pushing them further in can cause serious damage.
Excess Wax Build-Up
Cocker Spaniels naturally produce a lot of ear wax. When this builds up, it can cause:
- Blocked ear canals
- Pressure and irritation
- Reduced hearing
This discomfort frequently leads to head shaking, even in the absence of infection.
Regular ear cleaning is essential for this breed.
Ear Mites (More Common in Puppies)
Ear mites are less common in adult dogs but can affect puppies or dogs in contact with other animals.
Signs include:
- Intense itching
- Dark, crumbly discharge
- Frequent head shaking
Mites are highly irritating and require targeted treatment.
Water Trapped in the Ear
After swimming or bathing, water can remain trapped in a Cocker Spaniel’s ear canal.
This causes:
- Immediate discomfort
- Head shaking to dislodge water
- Increased infection risk if moisture remains
If head shaking starts shortly after getting wet, trapped moisture is a strong possibility.
When Head Shaking Becomes Dangerous
Persistent head shaking is not just uncomfortable—it can lead to serious problems.
Aural Haematoma
Forceful shaking can cause blood vessels in the ear flap to rupture, leading to a painful, swollen ear.
This condition:
- Requires veterinary treatment
- Can permanently alter ear shape
- Is extremely uncomfortable
Stopping the cause of head shaking early helps prevent this.
What You Should Do If Your Cocker Spaniel Keeps Shaking His Head
Step 1: Inspect the Ears
Look for:
- Redness
- Discharge
- Smell
- Swelling
Compare both ears—problems are often worse on one side.
Step 2: Clean if Appropriate
If the ear looks dirty but not painful:
- Use a proper ear cleaner
- Clean gently
- Observe for improvement over 24–48 hours
Never clean aggressively or probe deep into the ear.
Step 3: Seek Treatment if Symptoms Persist
If head shaking:
- Continues after cleaning
- Is accompanied by pain or discharge
- Is sudden and severe
Professional treatment is required. Repeated infections often indicate an underlying problem that needs addressing, not just repeated ear drops.
Long-Term Prevention Strategies
Regular Ear Care
- Weekly ear cleaning for most Cockers
- More frequent cleaning for infection-prone dogs
Keep Ears Dry
- Dry thoroughly after swimming or bathing
- Avoid frequent swimming if infections are active
Manage Allergies
- Consider diet trials
- Monitor seasonal patterns
- Reduce exposure to known triggers
Grooming
- Keep ear hair managed
- Ensure good airflow around the ear opening
Final Thoughts
When a Cocker Spaniel keeps shaking his head, it is almost always a sign of discomfort—most commonly related to the ears. Ignoring it or hoping it will stop on its own often leads to worsening infections, chronic inflammation, and painful complications.
By identifying the cause early and managing ears proactively, most Cocker Spaniels can live comfortably without constant irritation. Head shaking is a message. The sooner you listen, the easier it is to fix the problem.
