When an old dog suddenly develops head tilt, balance problems, or rapid eye movements, it can be frightening to witness. These symptoms often point to vestibular disease, a condition affecting a dog’s balance system.
We outline the key facts about old dog vestibular disease, what signs to look for, and when to seek veterinary help.
Old Dog Vestibular Disease — Why It Happens
Vestibular disease in older dogs happens when the inner ear or brain pathways that control balance are disrupted. Causes can include inner ear infections, idiopathic vestibular syndrome, brain tumors, trauma, and strokes.
Because the vestibular system is responsible for coordination and orientation, problems here can make a dog appear dizzy, disoriented, or unable to walk properly.
While some cases resolve on their own, others require urgent veterinary treatment, making it important for owners to understand what could be happening.
Old Dog Vestibular Disease: Common Causes
Idiopathic Vestibular Syndrome
This is one of the most common causes of vestibular disease in older dogs.
“Idiopathic” means the exact cause is unknown, but it often comes on suddenly. Dogs may wake up one morning with a severe head tilt, stumbling, or rolling to one side.
The good news is that this condition is not usually life-threatening. Most dogs improve significantly within a few days to weeks, although a mild head tilt may remain permanently.

Inner Ear Infections
Ear infections that travel deep into the inner ear can cause vestibular disease in senior dogs.
The infection disrupts the balance structures, leading to dizziness, loss of coordination, and nystagmus (rapid eye movement). Dogs may also show signs of ear discomfort such as head shaking, scratching, or discharge.
This type of vestibular disease can be very painful and requires prompt veterinary treatment with antibiotics, ear cleaning, and sometimes imaging. If untreated, the infection may worsen or spread.
Brain Tumors
Unfortunately, brain tumors are another possible cause of vestibular disease in old dogs.
When a tumor presses on the brainstem or vestibular nerves, balance is affected. Symptoms may include head tilt, circling, seizures, or changes in behavior in addition to wobbling and falling.
Because these signs can mimic other causes of vestibular disease, advanced diagnostics like MRI or CT scans are often needed. Brain tumors can be serious, but in some cases, medications can help manage symptoms and improve quality of life.
Stroke
Strokes in dogs occur when blood flow to part of the brain is disrupted, leading to sudden neurological signs.
A stroke affecting the vestibular system can cause dizziness, sudden loss of balance, and disorientation. Dogs may collapse, circle, or have difficulty standing.
Strokes can be alarming, but some dogs recover partially or fully with supportive care. Early veterinary attention is key to managing risk factors and preventing recurrence.
Trauma
Head injuries or trauma to the ear can also trigger vestibular disease in senior dogs.
A fall, accident, or rough play may damage the delicate structures of the inner ear or brain pathways. Owners might see sudden onset imbalance, tilting, or stumbling soon after the incident.
Trauma-related vestibular disease varies in severity. Some dogs recover quickly, while others may have long-term effects depending on the extent of the injury.
Hypothyroidism
Low thyroid hormone levels are sometimes linked to vestibular disease in older dogs.
Hypothyroidism affects nerve function and can contribute to neurological signs such as weakness, wobbliness, and balance problems. Other symptoms include weight gain, hair loss, and lethargy.
Treatment with thyroid medication often improves overall health, though vestibular symptoms may need additional supportive care.
What to Do If Your Old Dog Has Vestibular Disease
If your old dog suddenly develops signs of vestibular disease, the first step is to remain calm. While it can look like a stroke or life-threatening event, many cases—especially idiopathic vestibular syndrome—improve over time.
Help your dog by keeping them in a safe, padded area where they cannot fall or injure themselves. Remove obstacles and use non-slip rugs to prevent accidents on slick floors.
Offer food and water in easy-to-reach bowls, as some dogs struggle to lower their head due to tilting. Hand-feeding or elevated dishes may help.
Assist your senior dog outside for potty breaks using a harness or sling if they cannot walk steadily. Keep trips short and supervised until balance improves.
Always contact your veterinarian to determine the cause and ensure appropriate treatment. Even if symptoms improve quickly, a proper diagnosis is essential to rule out serious conditions.
When to Call or Visit Your Vet
You should seek veterinary attention immediately if your old dog suddenly shows severe imbalance, vomiting, or cannot stand.
Signs such as seizures, circling in one direction, changes in behavior, or head trauma require urgent evaluation. These may point to brain tumors, strokes, or other serious neurological problems.
If your dog’s vestibular symptoms do not improve within 48–72 hours, or if they worsen, a veterinary exam is critical. Prolonged symptoms often indicate an underlying issue that needs medical care.
Even in mild cases, scheduling a vet visit ensures peace of mind and helps guide supportive care at home.

Key Takeaway
Old dog vestibular disease is a common condition that can look dramatic but is not always life-threatening. Causes range from idiopathic vestibular syndrome and ear infections to brain tumors, strokes, trauma, and hypothyroidism.
At home, you can make your senior dog more comfortable with safety measures, support for walking, and easy access to food and water. But veterinary care is essential to confirm the diagnosis and rule out serious disease.
With patience, supportive care, and the right medical guidance, many dogs with vestibular disease go on to recover well and continue enjoying their golden years.
