My dog is a 10 year old Weimaraner. No other health issues. This happened today, I’m just wondering if it’s a seizure or some other neurological issue. He was aware the whole time, it looks like his eyes just got stuck like the muscles contracted and couldn’t relax. It lasted maybe 1 minute.. and went back to normal immediately after. Just wondering if anyone has seen this before, I do have a vet appointment just wondering what I should prepare myself for. Thank you in advance!
