Vestibular disease refers to a group of diseases that affect the balance system also known as the vestibular system. Common signs of vestibular disease (may also be known as vestibular syndrome) include loss of balance, falling, rolling over, abnormal flickering of the eyes and general wobbliness. The signs of vestibular disease often come on very suddenly and if your pet develops these signs it can be very frightening. Think how dizzy you felt the last time you came off a fairground Waltzer - this is how an animal with vestibular disease feels all the time. Many people mistakenly think that their pet may have suffered a stroke. However, most affected animals recover over a few weeks.
