Oh I do know what you are going through. My darling Jonah, my avatar, had idiopathic epilepsy. All that means is that they do not know why he has seizures. He started at 1 1/2 years and now at 8 years is on phenobarbitol, potassium bromide solution and leviteracetam twice a day. His seizures are under control but he now has cluster seizures, maybe up to 8 in a 24 hour period. He has not had any since the beginning of June. Jonah's seizures last about 30 seconds but then he has a period of blindness and agitation. Afterwards, he is his old adorable self. Then another one will come, and the toll they take on him is noticable, he gets progressively weaker with each siezure. He has has 2 episodes where he needed to be medicated in the doggy ICU for a few days, talk about expensive!! When the seizures start, we give him clonazepam to hopefully decrease the number of seizures. he is well drugged up for a few days. But then he recovers and is none the worse for wear.
My advice to you would be to learn all you can about canine epilepsy, the medications available and to see if there is a canine neurologist available where you live. Jonah goes to a wonderful doctor in Toronto. She is terrific with him and gives us sound advice. I would be happy to answer questions you have if you wish. Just send me a PM. Good luck. Hope your beauty stays well.
