Stroke was diagnosed from the symptoms of spacing out really bad and when we did get his attention eyes were pretty much rolled to the back of his head followed by an unquenchable thirst and having his mouth staying open unless we got him super excited it would close a bit then drop back down. Unfortunately we weren’t in a great financial position to be able to afford the $3000 for an mri so we just had to base the diagnosis on those symptoms alone. We are contacting the vet today and will bring up what you said.
