Vestibular disease is a sudden loss of balance caused by a problem in the inner ear or the parts of the brain that control balance.1,2 Signs come on suddenly, often within an hour:3,4
- A head tilt
- Stumbling, leaning or falling to one side
- Circling or rolling
- Flicking eye movements (nystagmus)
- Nausea and vomiting
The most common form, often called "old dog vestibular disease," has no known cause. It mainly affects older dogs. In UK records, dogs with vestibular disease had a median age of about 12.7 years.4,2 It looks frightening, like a stroke, but most dogs improve within about 3 days and are largely back to normal within 1 to 3 weeks.3,5,2 In one study, about half of dogs still had a lasting sign about a year later. A head tilt was the most common, in about a third.6 Inner ear infection is the next most common cause.6 Problems in the brain itself, such as stroke, inflammation or a tumor, are less common but more serious.5,7

What the Research Says
- It's a disease of old age. In UK records of over 900,000 dogs, about 8 in 10,000 had vestibular disease, at a median age of 12.7 years.4
- Some breeds are at higher risk. French Bulldogs had over 9 times the odds of crossbreeds. Bulldogs, King Charles Spaniels, Cavaliers and Springer Spaniels were also at higher risk.4
- Most cases have no known cause. In a 2020 study of 188 dogs with inner-ear vestibular disease, 68% were idiopathic, 26% had a middle or inner ear infection and 4% had hypothyroidism.6
- Some signs linger, and it can come back. At about a year, 52% still had a deficit, usually a head tilt, and 17.6% had another episode.6
Signs of Vestibular Disease
The vestibular system keeps the head, eyes and body level. When one side fails, the brain thinks the dog is falling and over-corrects.2 Signs include:3,2,4,5
- Head tilt toward the affected side, the most common sign
- Nystagmus: the eyes flick rhythmically side to side or round and round
- Wobbliness with a wide stance, leaning or falling to one side, circling and sometimes rolling
- Nausea: drooling, vomiting and refusing food, like motion sickness
- Reluctance to stand or move, and one eye that drops when the head is raised
Signs are usually worst in the first 24 to 72 hours.3,5 There's no good evidence that vestibular disease itself is painful. Pain when the ear or head is touched suggests an ear infection.9
Ear or Brain? Peripheral vs Central
The key question for your vet is whether the problem is in the ear (peripheral) or the brain (central). The answer changes the tests, treatment and outlook.2,1
| Sign | Ear (peripheral) | Brain (central) |
|---|---|---|
| Alertness | Normal | Often dull or confused |
| Leg strength and paw placement | Normal | Weak or clumsy, knuckling |
| Eye flicking | Side to side or rotating | Can also be up and down, or change direction |
| Other nerve signs | Drooping ear or lip, or a small pupil and droopy eyelid (Horner's syndrome) | Several other nerve problems |
| Outlook | Usually good | Depends on the cause |
Sources: Flegel (IVIS), Platt and Rylander.2,5,7 Up-and-down eye flicking almost always means a brain problem.2 A small stroke in the cerebellum can look exactly like old dog vestibular disease, so an MRI may be needed if signs are unusual or don't improve.10,11
Causes
Ear (peripheral) causes, in rough order of frequency:6,2,5
- Idiopathic (old dog) vestibular disease: no cause is found; sudden onset in older dogs
- Middle or inner ear infection (otitis media or interna). The outer ear can look normal. See dog ear infections.
- Hypothyroidism (underactive thyroid), which may be the only sign in some older dogs. See thyroid problems in dogs.
- Drugs and ear cleaners that damage the inner ear, including aminoglycoside antibiotics and some antiseptic ear cleaners, especially with a ruptured eardrum
- Polyps, tumors, head injury, and birth defects in some breeds
Brain (central) causes: inflammation or infection of the brain (encephalitis), stroke, tumors, head trauma and some drug toxicities.5,7,2 See stroke in dogs.
Diagnosis
Your vet will examine your dog's ears, eyes and nerves and check for weakness or poor paw placement.2,12 Tests may include:5,2
- A look at the eardrum, sometimes under sedation
- Blood tests, including thyroid levels
- MRI or CT of the head if a brain problem or deep ear infection is suspected, or if your dog isn't improving
Old dog vestibular disease is diagnosed by ruling out other causes.7,2
Treatment and Home Care
No treatment speeds up recovery from idiopathic vestibular disease. Care focuses on comfort while the brain adapts.5,2 Your vet may give:3,7,2
- Anti-nausea or motion-sickness medicine
- Fluids or a hospital stay for dogs that can't eat, drink or stand
- Antibiotics for an ear infection, often for at least 4 to 6 weeks. Surgery may be needed if it doesn't respond.
- Thyroid medicine if hypothyroidism is found
VCA advises that steroids generally aren't recommended, though UK records show they're often given.3,4 Don't give human motion-sickness pills without your vet's advice.
- Keep your dog in a small, padded area with non-slip flooring and away from stairs
- Hand-feed for the first few days if needed, and keep food and water by the bed
- Support your dog with a towel under the belly when going outside to toilet
Recovery and Outlook
With idiopathic vestibular disease, the eye flicking usually fades first, often within a few days.2 The head tilt and stumbling often improve over 7 to 10 days, and most dogs are largely recovered within 1 to 3 weeks. A head tilt or slight wobble can stay for good.3,8,5,2 A head tilt that remains can still improve slowly.2 Age alone isn't a reason to give up. Even very old dogs often recover well.4,6
The outlook for ear infections is usually good with long treatment. Some dogs keep a head tilt or a drooping lip.9,6 For brain causes, the outlook depends on the disease.5

Frequently Asked Questions
How long does vestibular disease last in dogs?
The worst signs usually ease within 3 days, and most dogs are much better within 1 to 3 weeks.
Can an old dog recover from vestibular disease?
Yes. The idiopathic form mainly affects dogs over 10, and most recover well.
Is vestibular disease painful for dogs?
It isn't thought to be painful, but it causes nausea and distress.
Is vestibular disease a stroke?
No, though some strokes cause the same signs. Your vet may need an MRI to tell them apart.
Can vestibular disease come back?
Yes. About 1 in 6 dogs had another episode within a year in one study.
