When your dog starts shaking their head persistently, it's natural to feel concerned. Head shaking is actually a normal behaviour that dogs use to clear their ears of water, dirt, or other irritants. However, when it becomes frequent or excessive, it usually signals that something is bothering your dog and needs attention.
Understanding the difference between normal and problematic head shaking can help you decide when to seek veterinary care. Occasional head shaking after a swim or during play is perfectly normal, but persistent shaking throughout the day, especially when accompanied by scratching or signs of discomfort, warrants investigation.
Most causes of excessive head shaking are treatable, particularly when caught early. By recognising the signs and understanding what might be causing your dog's discomfort, you can help ensure they get the right care promptly.
Types of Head Shaking in Dogs
It's important to distinguish between two different types of head movement in dogs. Deliberate head shaking is the voluntary side-to-side movement dogs use when they're trying to relieve discomfort or clear something from their ears. This is the type most commonly seen when dogs have ear problems.
In contrast, involuntary head tremors involve uncontrollable shaking, trembling, or bobbing movements. These are typically caused by neurological issues and require immediate veterinary attention. The tremors may affect just the head or can involve the entire body, similar to other forms of shaking or trembling in dogs.
Most cases of problematic head shaking fall into the first category, where dogs are consciously trying to address discomfort in their ears or surrounding areas.
When to seek veterinary care for head shaking
Occasional head shaking
After swimming, bathing, or during normal play. Usually resolves within hours.
Persistent daily shaking
Continues for more than a day, with ear scratching or visible discomfort.
Uncontrollable tremors
Involuntary movements, loss of balance, or neurological symptoms.
Common Causes of Head Shaking
Ear Infections
Ear infections are by far the most frequent cause of excessive head shaking in dogs. These infections create inflammation, itchiness, and discharge that make dogs instinctively shake their heads seeking relief. The warm, moist environment inside dogs' ears provides ideal conditions for bacteria and yeast to multiply.
Signs of ear infection include redness inside the ear flap, swelling of the ear canal, and discharge that may be dark, waxy, or have an unpleasant odour. You might also notice your dog scratching at their ears more than usual. Infections can develop deep within the ear canal, so an infection may be present even without obvious visible signs on the outer ear.
Certain breeds with floppy ears or narrow ear canals are more prone to infections, as are dogs that swim frequently or live in humid environments. If your dog experiences recurring ear infections, it's important to identify and address underlying causes.
Allergies
Both environmental and food allergies commonly trigger head shaking in dogs. Environmental allergens include pollen, mould spores, dust mites, and storage mites. These allergies often cause recurrent skin and ear problems that lead to persistent scratching and head shaking.
Typical allergy symptoms extend beyond head shaking to include red, inflamed skin, excessive licking of paws, and recurring ear infections. Seasonal patterns can provide clues about environmental allergies, whilst food allergies tend to cause year-round symptoms.
Dogs with allergies may develop secondary ear infections due to the inflammation and scratching, creating a cycle where the underlying allergy needs addressing alongside any resulting infections.
Foreign Objects
Dogs' natural curiosity and love of outdoor exploration can lead to various materials becoming lodged in their ears. Common culprits include plant debris, seeds, burrs, grass awns, dirt, and even insects. These foreign objects cause immediate discomfort and persistent head shaking as dogs try to dislodge them.
Grass seeds are particularly problematic as they can work their way deeper into the ear canal over time. If you suspect a foreign object in your dog's ear, avoid trying to remove it yourself, as this can push it further in or cause injury.
Water in Ears
Water trapped in the ears after swimming or bathing is a common and usually temporary cause of head shaking. However, if water remains in the ear canal for extended periods, it can create conditions that promote bacterial or yeast infections.
Dogs that swim regularly or have particularly hairy ear canals are more susceptible to water-related ear problems. The head shaking usually resolves once the water evaporates or drains out naturally.
Less Common but Serious Causes
Ear Mites
Whilst less common in adult dogs than puppies, ear mite infestations can cause intense itching and head shaking. These microscopic parasites create a characteristic dark, coffee-ground-like discharge in the ears. Ear mites are highly contagious between pets, so if one animal in a household is affected, others should be checked too.
Inflammatory Conditions
Certain autoimmune diseases and inflammatory conditions can affect the ears and surrounding skin, leading to head shaking. These conditions often present with additional symptoms like crusts, ulcers, and redness on other parts of the body, particularly around the face and ears.
Neurological Disorders
Some dogs may develop involuntary head tremors due to neurological conditions. These can include serious viral infections in unvaccinated dogs, congenital conditions affecting motor control, or unexplained tremors that are most common in young dogs under three years old.
Neurological head shaking differs from ear-related shaking in that it's typically involuntary and may be accompanied by other symptoms like loss of balance, difficulty walking, or changes in behaviour. Dogs experiencing balance issues may also appear drunk or wobbly. If you notice these signs, speak to your vet immediately.
Prevention and Management Strategies
Preventing Water-Related Issues
If your dog enjoys swimming or needs regular baths, several strategies can help prevent water-related ear problems. Consider placing cotton balls gently in your dog's ears before bathing or swimming, but ensure they're large enough not to get pushed into the ear canal.
Avoid spraying water directly onto your dog's head during baths. Instead, clean the face and ears with a damp cloth. For dogs that swim frequently, ear bands designed for canine use can help keep water out of the ears.
After water exposure, veterinary-approved ear drying solutions can help remove trapped moisture and prevent infections from developing.
Regular Ear Maintenance
Weekly ear checks can help you spot problems early. Look for signs of redness, discharge, or unusual odours. Keep your dog's ears clean and dry, but avoid using cotton buds or inserting anything deep into the ear canal, as this can cause injury or push debris further in.
If your dog has particularly hairy ears, your vet or groomer may recommend regular hair trimming to improve air circulation and reduce moisture retention.
Managing Allergies
If allergies are suspected, your vet may recommend specific approaches. Food trials involve feeding a single protein and carbohydrate source that your dog has never eaten before for several weeks to identify food sensitivities.
Environmental allergy testing through skin tests or blood work can help identify specific triggers. Where possible, avoiding known allergens can significantly reduce symptoms and prevent secondary ear infections.
Common signs accompanying head shaking

What to Expect at the Veterinary Examination
Your veterinarian will typically begin with a thorough otoscopic examination to look inside your dog's ears. This allows them to check for foreign objects, signs of infection, inflammation, injury, or structural abnormalities that might not be visible from the outside.
Additional tests may include ear swabs to identify bacteria or yeast under a microscope. If allergies are suspected, your vet might recommend allergy testing. For dogs showing neurological symptoms, a comprehensive neurological examination will be performed.
Blood tests may be necessary to rule out underlying conditions that could contribute to ear problems or neurological symptoms. Your vet will explain which tests are recommended based on your dog's specific symptoms and examination findings.
Treatment Approaches
Treatment varies significantly depending on the underlying cause. Bacterial or yeast infections typically require medicated ear cleaners and antimicrobial treatments. The specific medication depends on the type of organism identified through testing.
Allergy management might involve antihistamines, dietary changes, or immunotherapy depending on the type and severity of allergies identified. Foreign objects require professional removal, often under sedation to ensure safe extraction without pushing the object deeper.
Neurological conditions require specialised care and may involve supportive treatments to manage symptoms and maintain quality of life. Your vet will discuss the most appropriate treatment plan based on your dog's specific diagnosis.
The Importance of Early Intervention
Seeking prompt veterinary attention for persistent head shaking offers several advantages. Early treatment is typically more effective and less costly than addressing advanced conditions. Untreated ear problems can lead to permanent hearing loss or chronic infections that become increasingly difficult to manage.
Vigorous head shaking can cause blood vessels in the ear flap to rupture, creating painful swellings called haematomas that may require surgical treatment. Some neurological conditions can worsen rapidly without proper intervention, making early diagnosis crucial.
Most importantly, addressing the underlying cause quickly helps relieve your dog's discomfort and prevents the development of more serious complications.
Supporting Overall Wellbeing During Treatment
Whilst addressing the immediate cause of head shaking, consider your dog's overall comfort and wellbeing. Persistent head shaking and scratching can be physically demanding, particularly for older dogs or those with existing mobility concerns.
Maintaining good joint health through appropriate nutrition, regular gentle exercise, and MedPaw's hip and joint supplement can help ensure your dog remains comfortable and active throughout treatment and recovery. This is especially important if your dog needs to wear protective collars or has restricted activity during healing.
Remember that head shaking is your dog's way of communicating discomfort. By understanding the potential causes and recognising when professional help is needed, you can ensure your dog receives appropriate care to resolve the issue and return to their normal, comfortable routine.
How can I tell if my dog's head shaking is serious or just normal behaviour?
Normal head shaking happens occasionally after swimming, bathing, or play and usually stops within a few hours. Serious head shaking is persistent throughout the day, often accompanied by ear scratching, discharge, or signs of discomfort. If your dog shakes their head repeatedly for more than a day, or if you notice any uncontrollable tremors or balance problems, speak to your vet promptly.
What should I do if I think there's something stuck in my dog's ear?
Never attempt to remove foreign objects from your dog's ear yourself, as this can push the object deeper or cause injury to the delicate ear canal. If you suspect something is lodged in your dog's ear, contact your vet immediately for professional removal. They have the proper tools and expertise to safely extract foreign objects, often under sedation if necessary.
Can allergies really cause my dog to shake their head constantly?
Yes, both environmental and food allergies commonly trigger persistent head shaking in dogs. Allergies cause inflammation in the ears and surrounding skin, leading to itchiness and discomfort that makes dogs shake their heads seeking relief. You might also notice seasonal patterns with environmental allergies, red inflamed skin, or excessive paw licking alongside the head shaking.
My dog has been shaking their head after swimming - when should I be worried?
Head shaking immediately after swimming is normal as dogs try to clear water from their ears. However, if the shaking continues for more than a few hours after the water exposure, or if you notice any discharge, odour, or signs of discomfort, contact your vet. Trapped water can create conditions for infections to develop, particularly in dogs with floppy ears or those that swim frequently.
What's the difference between head shaking and head tremors in dogs?
Head shaking is deliberate, side-to-side movement that dogs control voluntarily when trying to relieve ear discomfort. Head tremors are involuntary, uncontrollable movements that dogs cannot stop and may involve trembling or bobbing motions. Tremors often indicate neurological issues and require immediate veterinary attention, especially if accompanied by balance problems or behaviour changes.
