dear delidog, rimadyl can be very helpful, but some dogs will have horrible reactions to it. did your vet suggest liver chemistry blood work to make sure delilahs' liver can tolerate the rimadyl?
BTW shais_mom i too am an xray tech south of you in columbus and on occasion i have wished that a patient could be mildly sedated too. i was knocked down by a patient once, luckily tho' none have tried to bite me.
