I had read in the article Bob's Dad sent to me on epilepsy about it occuring around the same time of day. But in Zoee's case it has been random. Once during the day while we were not home and mostly they are at night.
I hope you can find out what is wrong with Tucker. His sounds a bit more extreme than Zoee's. I mean less occurance but more severe symptoms.
What breed is Tucker? How old is he? Just curious...
