Definitely not a "good" morning.
We woke up at 4am from Rascal having a full blown seizure in bed. He was just laying on his side, seizing, couldn't breathe, frothing at the mouth. We were 100% sure that he was dying right then and there. The scariest thing I've ever seen... He almost had another seizure 1,5h later but it stopped before it got really bad.
He's completely back to normal now, we have gone for a walk and he's had breakfast and a snooze. Sonny and I couldn't sleep anymore after it happened so we're really tired. We have spoken to a vet and to our breeder and have an emergency vet appointment at 10. Hopefully they'll be able to draw some blood and start crossing things of the list.
Best case scenario is that it was just a one time thing, it can happen to all dogs at some point in their life. Worst case scenario he has some kind of tumor or other illness that causes this neurological reaction. And it is of course possible that he has some kind of epilepsy, in which case he will take medication for the rest of his long and happy life.
Regardless we'll do our best to figure out what's wrong. We're all crossing our paws that it's nothing too serious and we try not to worry too much. He's not suffering that we know of, he's not in pain when it happens and dogs don't live with the fear of "another seizure" the way humans might.
