I admit I didn't read responses, but one of my mom's dogs is being treat ed for Epilepsy. He is now 3, and had his first seizrues last summer. Not as young as your dog, but still a young dog. His first, he had about 5 seizures in a 36 hour time period. He was put on Phenobarb, and went seizure free for about 7 months. Then, Easter weekend he had 3 more. The vet checked his phenobarb levels (which were fine) and at this point, since he seizures have been so infrequent, they have deicded not to change anything.
