Well no more seizures or whatever, but the phenobarb is making him pretty much lose any ounce of self control he had, he's always been a vocal high energy dog, but now he is extremely whiny, back to being reactive on walks, screaming in the kennel, clingy even more than usual. I've read the side effects should diminish within a few weeks and I really hope so. I guess we are going to test his levels in a couple weeks, keep him on the meds for six months and then try to wean him off the meds is the plan and see how that goes. My other vet concurred that it looked like a seizure and to try this. I hope he doesn't have any more, it's really got my boyfriend worried about leaving him at all and he's gotten to sleep on the bed with us every night since (normally we rotate dogs because 3 don't fit).
