It can be concerning when your dog develops a head tilt and begins shaking. While an occasional head shake after waking up or getting water in the ears is normal, a persistent head tilt combined with repeated shaking usually indicates an underlying medical problem.
Ear infections are the most common cause, but vestibular disease, ear mites, allergies, foreign objects, or neurological disorders may also be responsible.
Because these conditions can worsen if left untreated, prompt veterinary evaluation is recommended.
Dog Head Tilt and Shaking: Why It Happens
A dog may develop a head tilt and shaking because of an ear infection, vestibular disease, ear mites, allergies, a foreign object in the ear, or another condition affecting the ears or nervous system.
Additional symptoms such as loss of balance, ear discharge, or rapid eye movements can help determine the underlying cause.

Common symptoms may include:
Head tilt
Frequent head shaking
Scratching at the ears
Ear discharge
Loss of balance
Walking in circles
Red or swollen ears
Pain when the ears are touched
Dog Head Tilt and Shaking: Common Causes
Ear Infection
One of the most common causes of head tilting and shaking is an ear infection.
Bacterial or yeast infections cause inflammation inside the ear canal, making the ear painful and itchy. Dogs often shake their heads repeatedly to relieve the irritation while tilting their heads toward the affected side.
Additional signs include redness, swelling, dark discharge, a foul odor, excessive scratching, and discomfort when the ear is touched.
Without treatment, an outer ear infection can spread deeper into the middle or inner ear, leading to more serious balance problems.

Idiopathic Vestibular Disease
Vestibular disease is another common cause, particularly in senior dogs.
The vestibular system controls balance and body position. When it suddenly becomes affected, dogs often develop a noticeable head tilt along with stumbling, leaning to one side, circling, or falling over.
Some dogs continue shaking their heads because they feel dizzy or uncomfortable. Rapid eye movements (nystagmus), nausea, and vomiting are also common.
Although the symptoms can appear dramatic, many dogs begin improving within several days and recover significantly over one to three weeks with supportive care.

Middle or Inner Ear Infection
Infections affecting the middle or inner ear are more serious than routine outer ear infections.
These infections directly involve the balance organs inside the ear, causing both a persistent head tilt and repeated head shaking. Dogs may also lose their balance, walk in circles, or develop hearing loss.
Treatment often requires oral medications in addition to medicated ear drops, and some cases need advanced imaging or surgery.
Prompt treatment improves the chances of a full recovery.
Ear Mites
Ear mites are tiny parasites that can cause intense ear irritation.
Affected dogs frequently shake their heads and scratch at their ears because of severe itching. Some also hold one ear lower than the other or develop a slight head tilt because of discomfort.
A dark, crumbly discharge resembling coffee grounds is often present, particularly in puppies and young dogs.
Veterinary treatment is needed to eliminate the mites and relieve the irritation.
Foreign Object in the Ear
A foreign object inside the ear can trigger sudden symptoms.
Grass seeds, small insects, plant material, or other debris may become lodged deep within the ear canal. Dogs often begin violently shaking their heads immediately after the object enters the ear.
They may also paw at the ear, cry when it is touched, or keep their head tilted toward the affected side.
Your veterinarian can safely remove the object without damaging the ear.
Allergies
Dogs with allergies frequently experience recurring ear problems.
Environmental allergens such as pollen, grass, mold, or dust mites, as well as food allergies, can cause chronic inflammation inside the ears. The irritation leads to repeated head shaking and may eventually result in infections that cause a head tilt.
Many allergic dogs also lick their paws, scratch their skin, or rub their faces.
Managing the underlying allergy helps reduce future ear problems.
Neurological Disorders
Less commonly, head tilting and shaking may result from problems affecting the brain or nerves.
Brain tumors, inflammatory brain disease, strokes, or head trauma may interfere with the nerves that control head position and balance.
Dogs with neurological disease often develop additional symptoms such as seizures, weakness, circling, abnormal eye movements, behavior changes, or difficulty walking.
Neurological causes require immediate veterinary evaluation.

Dog Head Tilt and Shaking: What to Do
Observe whether your dog consistently tilts their head toward the same side.
Check the outer ear for redness, swelling, discharge, bad odor, or obvious debris, but do not insert cotton swabs or other objects into the ear canal.
Prevent excessive scratching, as this can cause bleeding or a blood-filled swelling of the ear flap (aural hematoma).
Keep your dog indoors and avoid vigorous exercise until they have been examined if they are also losing their balance.
Record a video of your dog’s head movements and walking, as this can provide valuable information for your veterinarian.
When to Call or Visit the Vet
Contact your veterinarian immediately if your dog develops a persistent head tilt or repeated head shaking.
Schedule an appointment if you notice:
Persistent head tilt
Frequent head shaking
Ear discharge
Bad odor from the ears
Scratching at the ears
Pain when the ears are touched
Seek emergency veterinary attention immediately if your dog develops:
Loss of balance
Falling over
Walking in circles
Rapid eye movements
Seizures
Sudden inability to stand
Dog Head Tilt and Shaking: Treatment
Veterinary assessment includes a physical examination to carefully inspect your dog’s ears using an otoscope.
Depending on the suspected cause, diagnostic testing may include ear cytology to identify bacteria, yeast, or mites, bloodwork, neurological examination, blood pressure measurement, CT scan, MRI, or referral to a veterinary neurologist.
Treatment depends on the underlying diagnosis and may include medicated ear drops, oral antibiotics, antifungal medications, parasite treatment, anti-inflammatory medications, anti-nausea medication for vestibular disease, or specialized treatment for neurological disorders.
Recovery and Monitoring
Recovery depends on the underlying cause. Most uncomplicated ear infections improve within one to two weeks with appropriate treatment, while idiopathic vestibular disease often shows noticeable improvement within several days.
Recovery from middle ear infections or neurological disorders may take longer and often requires ongoing monitoring.
Monitor your dog’s balance, appetite, ear condition, and overall behavior during recovery. Complete all prescribed medications, even if symptoms improve early, and attend follow-up appointments to ensure the underlying condition has resolved completely.
Key Takeaway
A dog with a head tilt and shaking most commonly has an ear infection, but vestibular disease, ear mites, allergies, foreign objects, middle ear infections, and neurological disorders are also possible causes.
While occasional head shaking is normal, a persistent head tilt is never considered normal and should always be evaluated by a veterinarian.
If your dog develops loss of balance, falls over, walks in circles, has seizures, or suddenly cannot stand, seek emergency veterinary care immediately.
Early diagnosis and treatment can improve recovery and help prevent long-term complications.
