I have 2 Irish setters both male and healthy, Flynn is my oldest at 4 1/2 years. This morning he was laying on the couch, I was putting my shoes on to go let the chickens out and wham, Flynn falls off the couch in a full Grand Mal Seizure. I moved everything out of his way and tried to talk to him while it was going on. This is a first for us, he's never shown any form of epilepsy, he hasn't had access to any chemicals or anything poisonous that I know of. I called my friend who is a vet tech and she told me what to expect after the seizure was over. He made it through ok, it took about 3 hours for him to get back to normal. This was a serious one with foaming mouth and lot's of thrashing. The vet says they can't do anything but to monitor it for now. They think it's strange for a dog his age to start having epileptic seizures, usually it starts before the age of two statistically. So my question is, have any of you ever had something like this happen? I'm hoping it's a one time deal, but I know life is usually not that simple. Sorry this is a little long. Thanks for any input.
