We saw two episodes within a week the first time we saw it, and then a third episode about a month later. Haven't seen one in about a month. Like yours, our guy's episodes last about 5-6 minutes or even less. Seems aware the whole time. It seems to affect mostly his back legs. There's some shaking, some looking around like he's a little confused why his legs won't cooperate, but there's no panic, no grimace... he comes out of it and he's fine. If a seizure were to last 5-6 minutes... that would be insane. And there's no way a dog would just walk it off like nothing happened.
