We had a cocker spaniel that had seizures starting when he was about 5 years old. Our vet did a lot of research (me too) and came to the conclusion that cocker spaniel's sometimes have an ammino acid deficit. He suggested two over-the-counter supplements that I could give him and yes, they were less frequent. Also, our pets deplete a lot of energy during these seizures. I always gave my pooch a teaspoon of vanilla ice cream after his seizures to bring his sugar levels back up. Also keep a record of date and time and length of seizures for your vet.
