Woke up one night to find my dog, Sunny, in a heap, unable to stand and panting anxiously. Vet diagnosed it as Geriatric Vestibular Disease. Somewhat common in older dogs (Sunny is 14) symptoms include: eyes darting about irregularly; loss of balance; and upset GI tract. No cause is known. No treatment other than time. Most dogs seem to recover within a few days or weeks. Residual head tilting is common. The vet assured us this was NOT a stroke. However, the symptoms sure looked like it at the time. Took this video on day three, when Sunny came home. She is still unsteady, but managed to make the one step up to get into the house. The panting may be partly due to anxiety – and it was warm on this day. Curiously – Sunny stops when she reaches her bed; and cannot seem to figure out how to lie down. I finally tell her, “Sit”, and she slowly drops down to rest.
