My cocker spaniel had epilepsy, it sounds very similar to what your dog is going through. With my dog, it seemed to happen when he was really excited. One of the worst seizures he ever had was on Thanksgiving. He was very food motivated and just got way too excited. He would lose all control over his bowels so don't be alarmed, it's very common. It will seem like she is aware of what is going on, but most likely, she is blacking out. My dog would appear to be looking at us as well. He was never put on medication because the vet told us the side effects from the drugs were often times worse than the seizures themselves. My dog only seemd to have the seizures about once or twice a year though. He lived to be 15 without any real problems from the epilepsy. I would definitly check into it though. There may be some underlying reason for Ava's seizures that needs attention. I'm sorry you're going through this, I know how terrifying it is to see your baby like that.
