Well my dog's a beagle (and like 99% of beagles have epilepsy). He usually has them in bursts, he'll go quite a few months without any (I think it's been about a year since I've seen him have one) then he'll have like 3 in a month.
They're not bad, his muscles just lock up and he can't move and he shakes a lot.
I was watchin round one of Fitch n Alves and he hopped off the futon and walked up to me and sat down in front of me facing the other way, and I was like WTF u doing?
And he didn't come when I called him so I moved over to him and realized he was havin one

Not anything you can do besides make sure he stays laid down cuz he will try and get up and walk...I usually just lay on top of him (no pressure of course) and sing Don't Worry Be Happy

He's okay though

he's all tail-wagging and everything again.
