I have a english mastiff with epilepsy. It's a horrible thing to see a 180 pound dog go through a seizure. We have him on keppra and phena barbitrol. This has been working for him. The vet had him on keppra twice a day and he still had seizures so they added the phena barbitrol and so far that has prevented any more seizures. He such is a nice dog, not really good for anything other than companionship.
