Thats a shame Bev
My vet said to make the room dark if possible and not to talk to Jack, just quietly observe that he is ok and make sure he is safe.
He once bumped into the ironing board which was leaned against the wall, it fell over and just missed our old dog who was in her bed! we have had to intervene a few times to get him out of weird places, he sometimes tries to get between the wall and the freezer which is a very tight squeeze!
I let Jack out once just after a seizure whilst i cleaned up his puddle, he jumped over our wall and went missing in the village it was terrifying, he didnt know what he was doing
