I haven't posted in a LONG time but do read almost daily to keep up.
Anyway this morning (4:30 to be exact) I heard some rattling from Mooches in his crate. I checked on him and he was standing with his head braced in the upper corner of his crate, panting heavily. He was not very alert and when I nudged him he slumped tithe ground half in and out of his crate. I dragged his dog bed in front of him and lifted on to it. I rushed him to the e-vet and he was calm but not alert and also wobbly. After we'd been there awhile he got up and started walking in circles - not upset but just determined and occasionally bumping into things. The vet said it was likely old dog vestibular syndrome which has a good prognosis. He also mentioned that he didn't have the typical head tilt or nystagmus. I left him there to be observed while I'm at work.
Anyway I was just bothered because Mooches didn't seem to recognize me or respond to his name though by the time I left he was pretty steady on his feet (still walking in circles). Anyone have any experience with this? Is this normally part of this syndrome? He's 13 so I'm afraid that he has had a stroke or something.

He's home now and seems about 90%. His balance is fine, no circling and no tilt. He seems a bit spacey and restless - to me he seems more post-seizure like but there would be nothing additional to do in that case either. Just wait and watch. Thanks for all your good thoughts and wise words
