Sunday morning, I woke up to my dog have what may have been a seizure. She will be 13 in October (average lifespan for a Shih-tzu). She was under the covers and wanted to get out, so I pulled up the covers, but she seemed disoriented and kept trying to pusher her way out the other direction. So I tapped her on the butt to turn her around and she stared walking towards me. The next thing I know, her she was falling over herself, her legs going in different directions and she fell over. She stretched her head out and made a loud whining sound and then started panting loudly. She did not respond when I called her name and it took her 2 minutes to recover and sit up. She was still disoriented, but acknowledging me at this point. I called my vet and they said that it sounded like a seizure but that it was best to wait and see if she had another one before bringing her in. An hour later she was up, running around and eating like normal.
So, or course I googled it... because why the hell not? And the one thing that kept coming up over and over again was brain tumor. She is the right age. The right breed... I have set up an appointment with my vet to discuss this and to get her looked at, but I don't know... Anyone else have experience with this? What else could cause a seizure in a dog her age?
