My dog Rose has seizures, too. The vet started her on phenobarbitol (PB), and for awhile she did not have them so often. But as time went on, they got closer together (every one to two weeks) and even increasing the dosage of the PB didn't help. We then went to using potassium bromide (KBr) in combination with the PB. We are now gradually weaning her off the PB because of the ill effects it can have on the liver. She's been seizure free for almost two months now.

The Kbr doesn't have the bad longterm side effects that the PB does. The only catch is that it doesn't come all nicely packaged in pills - you have to get it from a compounding pharmacy that will mix it for you. You may want to discuss this option with your vet.

In any case, I wish you luck and will keep Presley in my prayers. Feel free to email me if you want to talk more.
