Our dog first had seizures around two years old. He's now 5 1/2.
He is highly vocal, expending a lot of energy on barking and can rush around like spinning top. The first time it happened it was incredibly hot(he's a black curly poodle), he was running around and barking in greeting at DH who had just come home.
Because it was a one off the vet was not overly concerned as it could have been heat related. But three days later he had a cluster of three, short duration but one after the other.
These were not big body shaking seizures but still awful to see, wobbling, vision impaired, unable to respond, slow collapse to the floor and disorientation.
We did the whole shebang of testing, luckily we are on Petplan and the costs were covered, about five and a half grand. In between starting the testing and diagnosis he probably had a dozen seizures in clusters. He had one big one and that scared the life out of me, luckily it was short and I managed to stop him hurting himself.
His diagnosis is now Idiopathic Epilepsy. In other words there is nothing they can pin it on (personally I think it is his ability to wind himself up into an excited frenzy). He now takes Epiphen 30mg twice a day for the rest of his life.
Since starting the medication he has had two minor episodes. Both after chasing a scent trail in the forest.
After a period of lethargy the medication made him ravenous and incredibly thirsty but other than that he is still the same loving, daft dog.
