"Belle the beagle has epilepsy and has seizures, grand and petit, about once a month. She doesn't get them frequent enough to treat her with epilepsy medication (but if the seizures become more frequent we will put her on meds). We read that putting an ice pack on the small of her back when the seizure begins will help bring her body temp down and prevent the seizure from getting worse. Amazingly it works for her. Belle recovers much faster and the seizures never evolve into a grand mal. We hope this video helps others when they're not sure what to do when their dog has an epileptic seizure. Belle was 5 years old at the time of the video."
Might be worth of try.
