Acute canine vestibular syndrome causes sudden, alarming neurological signs in dogs that are frequently mistaken for stroke, with most cases being idiopathic and resolving without treatment over days to weeks.
Acute vestibular syndrome causes severe, acute distress in affected dogs through profound disorientation. Dogs in the acute phase cannot walk, may fall and roll uncontrollably, and show rapid eye movements causing visual disturbance. Nausea from vestibular disturbance compounds the disorientation. The welfare impact during the acute phase is significant despite the typically good prognosis. Supportive care focusing on preventing injury from falling, ensuring hydration and nutrition, and maintaining a calm, low-stimulation environment is central to acute welfare management. Anti-nausea medication improves welfare during the acute phase. Owner education is crucial — many dogs with vestibular syndrome are euthanized due to misidentification as terminal illness when they would have made a good recovery with supportive care. Identifying idiopathic vestibular syndrome promptly prevents unnecessary euthanasia.
