Still no seizure

Mickey hasn't had a seizure for 14 weeks...but I'm worried about him still being on the PhenoBarbitol. I thought he wasn't supposed to be on it for more than 3 months but the vet hasn't said anything about it.

He hurt his paw somehow several weeks ago. It was getting better and he didn't limp any more but we took him to the off-leash dog park in Marymoor and he ran alot. Then we went for a walk the next day. That night he began to limp again. He needs exercise but I'm worried he will reinjure his paw.
