Hi folks, I need some opinions please! I think my almost 11 year old Shih Tzu, Jasmine, may have had a seizure yesterday morning. My younger Tzu was barking at Jasmine while she was laying on her blanket, I walked by & Jasmine stood up to walk & took a step & fell to her side, her back legs wouldn't work, she got up & fell over again & then was rolling on her back paddling all her legs, this all lasted maybe 30 seconds tops. She's never done anything like this before, that I've seen at least. I picked her up & her pupils seemed huge. I held her for a few minutes & when I put her down she walked away like normal & went & laid down & took a nap. Having never seen a seizure before, does that sound like what it could have been, or maybe something else.
I am calling the vet tomorrow to get an appointment for bloodwork & a physical. She doesn't have any medical issues I know of besides environmental allergies.
