Idiopathic vestibular disease is a common, frightening sudden-onset condition in older dogs that resolves in most cases but requires careful welfare management.
The acute phase of vestibular disease is extremely distressing for both dogs and owners. Dogs cannot stand, fall when attempting to walk, and experience continuous nausea from disrupted balance. Welfare priorities in the first 24-72 hours include anti-nausea medication, a quiet low-stimulation environment, assisted feeding and drinking, and prevention of self-injury from falling. Owner education about the high rate of spontaneous recovery is critical to prevent premature euthanasia decisions.
