Google vestibular disease Ms. I. My dog had it a few months ago... it's balance issue, related to inner ear. It was a scary situation no doubt, but she's come back strong.

Be careful with stroke symptoms all. Vestibular disease has the symptoms of stroke: sudden, eyes glossed over, unable to stand, let alone walk... when I saw her that morning, I thought this could be it
. But I've read stories about folks who had their dog put down because they were told their dog had a stroke, who in hindsight believe they had the symptoms of "just" vestibular disease. That would be terrible to consider (that you killed your own dog).
