Idiopathic vestibular disease causes sudden, dramatic loss of balance in older dogs that is frightening for both animal and owner, but typically resolves within 2-4 weeks with supportive care.
Acute vestibular disease causes intense distress — disorientation, nausea, and inability to control body position are profoundly frightening for a dog. The sudden onset and dramatic presentation mean owners often fear their dog has had a catastrophic stroke or is dying, adding anxiety that can inadvertently stress the animal further. Supportive care — a calm environment, anti-nausea medication such as maropitant, and gentle assistance with position changes — significantly improves comfort during the acute phase. Preventing self-injury during episodes of rolling is essential. The welfare trajectory is almost universally positive for idiopathic cases; the key welfare intervention is rapid diagnosis to exclude central causes, prompt anti-nausea treatment, and patient nursing care through the recovery period.
