TL;DR
Vestibular disease in older dogs is a sudden loss of balance: a head tilt, falling or circling to one side, flickering eyes and sometimes vomiting from motion sickness. It looks like a stroke and frightens owners, but the most common cause, idiopathic ("old dog") vestibular disease, usually improves on its own over days to weeks. In a study of 188 dogs with problems in the inner-ear part of the balance system, 128 (68%) had idiopathic vestibular disease and 49 had a middle or inner ear infection; older age made the idiopathic form more likely. Recovery is often incomplete, though: 50 dogs kept some head tilt long term and 26 had another episode. Signs such as weakness on one side, sleepiness, seizures or confusion point to a problem in the brain itself, such as a true stroke or tumor, which needs urgent care. Every dog with sudden balance loss should see a vet the same day to tell these apart.
Signs of vestibular disease in dogs
| Sign | What you might notice |
|---|---|
| Head tilt | Head held to one side, often suddenly |
| Loss of balance | Leaning, falling or rolling toward one side |
| Circling | Walking in tight circles in one direction |
| Nystagmus | Eyes flicking side to side or up and down |
| Strabismus | One eye drops lower when the head is lifted |
| Nausea | Drooling, vomiting, refusing food, like motion sickness |
| Wide stance | Legs splayed to stay upright |
| Facial droop | Drooping lip or ear, or one eye not blinking |
In the 188-dog study, almost every dog had a head tilt (185), and many had unsteadiness (123), facial paralysis (103), flickering eyes (97) or a dropped eye (93).
Is it a stroke?
Vets first work out where the problem is:
| Peripheral (inner ear or nerve) | Central (brain) | |
|---|---|---|
| Alertness | Normal, if nauseous | Can be dull, sleepy or confused |
| Leg strength and placement | Normal | Weakness or poor foot placement on one side |
| Eye flicker | Usually side to side | Can be vertical or change direction |
| Common causes | Idiopathic vestibular disease, ear infection, underactive thyroid | Stroke, tumor, inflammation of the brain |
| Outlook | Usually good | Depends on cause |
A review of vestibular disease stresses that this distinction drives everything: the likely cause, the tests and the outlook.
True strokes in dogs
Strokes do happen in dogs, and the outlook is better than many people expect. In a study of 22 dogs with MRI-confirmed ischemic stroke, 23% died within the first 30 days, but survivors lived a median of 505 days after the event, and 41% of 30-day survivors had an excellent recovery. Some had a further neurological event months later.
Causes of peripheral vestibular disease
In the 188 dogs (median age 6.9 years):
| Cause | Number of dogs |
|---|---|
| Idiopathic vestibular disease | 128 |
| Middle or inner ear infection | 49 |
| Hypothyroidism | 7 |
| Congenital | 2 |
| Tumor | 1 |
| Cholesteatoma (ear cyst) | 1 |
Idiopathic ("old dog") vestibular disease
"Idiopathic" means no cause is found. It comes on suddenly, mostly in older dogs, and is at its worst in the first day or two. Many dogs start to eat and walk better within days, though a slight head tilt may stay.
Ear infection
An infection that spreads past the eardrum into the middle or inner ear can cause the same signs. Ear infections are very common: otitis externa affected 7.3% of UK dogs in a year. Dogs with a history of ear problems, head shaking or a smelly ear need an ear exam and sometimes imaging. See dog itchy skin, which covers allergies that often drive ear infections.
Treatment
There is no specific cure for idiopathic vestibular disease; care is about comfort while the brain adapts:
- Anti-nausea medicine so your dog will eat and drink.
- Fluids if your dog cannot drink.
- Antibiotics and ear treatment if an ear infection is found.
- Thyroid hormone if hypothyroidism is found.
- Treatment of the brain cause for central disease.
Caring for a dog with vestibular disease at home
- Confine your dog to one padded room with non-slip flooring, away from stairs and furniture edges.
- Support it to walk with a towel sling or harness under the belly. See support harness for senior dogs.
- Hand-feed and hold the water bowl at first, while your dog is too dizzy to stand steadily.
- Keep it clean and dry if it cannot get up, turning a large dog every few hours.
- Keep the lights on at night; vision helps balance.
- Go back to the vet if your dog gets worse after the first few days, becomes dull, has a seizure or cannot eat.
How long does it last?
Most improvement happens in the first days to weeks. In the 188-dog study, long-term follow-up found:
- Persistent head tilt in 50 dogs.
- Persistent facial weakness in 41 dogs.
- Ongoing unsteadiness in only 6 dogs.
- Recurrence in 26 dogs.
Interestingly, dogs that had a previous episode were more likely to recover fully from the next one, while inflamed nerves on MRI were linked to a lower chance of full recovery. Most dogs with a lasting head tilt live comfortably and learn to compensate.
For older dogs who are already a bit wobbly on their back legs, balance loss is harder to manage. See senior dog back legs shaking and senior dog care at home.
FAQ
What is old dog vestibular disease?
A sudden loss of balance in older dogs, with a head tilt, falling, flickering eyes and nausea, where no cause is found. It usually improves on its own over days to weeks.
Is vestibular disease a stroke?
Usually not. The idiopathic form affects the inner-ear part of the balance system. A true stroke affects the brain and often causes extra signs such as weakness on one side or dullness. A vet exam tells them apart.
How long does vestibular disease last in dogs?
Most dogs improve noticeably within days to weeks. Some keep a slight head tilt for life, and a minority have another episode.
Should I put my dog down for vestibular disease?
Not in the first days. Idiopathic vestibular disease looks dramatic but most dogs improve. Give it time with your vet's support unless tests show a serious brain cause.
Can dogs recover from vestibular disease?
Yes, most do. In a study of 188 dogs, ongoing unsteadiness persisted in only 6 dogs, though a head tilt or facial weakness lingered in more.
