I'm sorry to hear that. We had a Maltese Poodle that had seizures when I was 12 that had to be euthanized. He got hit by a car then had seizures after that. Also one of my Basenjis had them occasionally for a few years then they stopped. The vet said that because she would get so wired up and excited that her brain's electrodes would misfire. She calmed down over time.
