My dog Lacie started having seizures when she was a year old. My vet said she needed to have more than one per month before he would put her on medication. She was on pheno-barbitol for ten years. It stopped her seizures completely. It does cause liver damage in the long run, so make sure her dosage is monitored closely. I eventually weaned Lacie off pheno-barbitol when she was eleven years old. It took a year of gradually reducing the dosage. She no longer has seizures, or takes medication. Sometimes they do stop.

My vet said that it was probably epilepsy, or could be some other seizure disorder. She said she could run all kinds of expensive tests, tell me the name of the exact disorder she had ... and put her on pheno-barbitol anyway, no matter what. So, I didn't have the testing done. I'm sure each case is different.

I would talk to your vet again. If he/she is still unwilling to re-evaluate the situation, I would get a second opinion.
