I've also been told that a bit of Karo syrup may help. My neighbor's dog had seizures, and she used to call me all the time because she didn't handle them well-she had me give him Karo syrup.
I had a dog that had occasional seizures too. His were so infrequent that he was never on meds. He knew when they were coming on, as he would run to me. I absolutely disagree that he couldn't hear me, or know that I was with him. I KNOW it shortened my guy's seizure time, and he knew exactly where he was and that I was there when he stopped seizing.
