If there was any doubt that Taz gets seizures, that was put to rest today. We have been wondering with his occasional manic states that are a little similar to how Oz would be after a seizure (combination of frightened and confused). Once I wasn't sure if he was choking or seizing. We've meant to bring it up during visits to the vet, but it's slipped our minds. Today he had a full blown episode, followed by a couple hours of manic behaviour, Just when I thought he'd settled down, I realized he'd managed to squeeze through the fencing in back and had run off.
I gathered Oz, leashes, and several baggies for poop-stops and went out looking for him when some calling from the front porch didn't work. Luckily, he rounded the corner at the end of the block shortly after I left the driveway going in that direction. The three of us walked a little longer to try to burn off whatever energy he still had. Now he's finally sleeping.
I guess we'll be taking another trip to the vet, as well as finding new ways to secure the backyard so he doesn't decide to go wandering again.
