Vestibular Disease
Sudden loss of balance and head tilt in older dogs — dramatic but often idiopathic and self-resolving.
What is Vestibular Disease?
The vestibular system tells the brain where the body is in space. When it malfunctions, dogs suddenly develop a head tilt, loss of balance, and rapid eye movements (nystagmus). 'Old dog vestibular disease' (idiopathic) is the most common cause and, despite being frightening to witness, usually improves within days to weeks.
Common signs and symptoms
Signs vary between dogs and can be subtle at first. Watch for the following, especially if several appear together or persist for more than a few days:
- Sudden head tilt
- Loss of balance, staggering, falling to one side
- Rapid rhythmic eye movements (nystagmus)
- Nausea, drooling, and reluctance to eat
- Circling or rolling
Risk factors
Certain dogs are more predisposed. Understanding risk helps you screen earlier and act sooner.
- Senior dogs (typically 8+)
- Chronic ear infections (peripheral vestibular disease)
- Hypothyroidism
When to see a vet
Use this as general triage guidance, not a substitute for veterinary advice.
- Book a routine appointment if: any sudden loss of balance in a senior dog should be seen the same day to rule out treatable causes.
- Seek urgent care if: if it's paired with weakness on one side, changed mental status, or seizures — this suggests central vestibular disease, which is more serious.
Diagnosis and management
Diagnosis distinguishes peripheral (ear-related, better prognosis) from central (brainstem, needs MRI). Idiopathic cases typically improve within 72 hours and resolve within 2–3 weeks. Supportive care includes anti-nausea medication, help walking outside, and non-slip footing.
