I took my 11 yr old JRT to the emergency vet yesterday as he was falling over, had been sick and couldn't walk straight. The vet seems fairly confident it is vestibular disease. The dog initially showed a few signs of improvement but is very wobbly again today. He's not interested in food but has had some water. Does anyone know how long these episodes tend to last and how often they might happen ? Any other advice gratefully received. Its such a distressing sight so I really hope its something that will pass.
