Hi Maxx's dad,
I also have complex partial seizures. I can't really tell you 100% what it is like during a seizure because I lose much my memory surrounding the seizure - a little before, throughout, and even after. From what I remember, before I knew they were seizures I would be confused. Then I would get up an fall and not be able to get up again. And I couldn't talk and feel frustrated and confused. But I didn't feel scared. Although, that is just my memory now, so perhaps during them I really did.
I also have a dog who has had seizures and he is also the dog who comes by my side and stays there until I am able to get up if I fall. He means a lot to me, I feel like he saved my life, too. I have another dog who watches me during, but she is skittish generally and the seizures frighten her so she watches from afar. My dog, Buster, hasn't had a seizure in awhile and was never on medication. He had them when he was under 2 years old. He would stiffen up, fall to the side, and his paws would - sort of shake, sort of "run" - and a little foam/vomit would come out of his mouth. Right before this would happen it would sound like he would yelp. It lasted a matter of less than 30 seconds, and then up he would pop, he would come near me, and fall deep asleep for hours. Scared the heck out of me. The vet said if it happened more frequently they would run tests and put him on meds, but it happened maybe 3 times in 8 months, then 2 more times in a year. Then it just stopped. Maybe that's why he comes to me when it happens to me.
I'm sorry about Maxx. I hope he will be ok.
