My rabbit had a leg injury (cause unknown). The vet said it's not broken and prescribed rimadyl for pain. It is still three hours until his next dose, But he is showing signs of pain. Can I cut the doses in half and increase the frequency to every six hours or is that not going to give him relief with half doses? Signs of pain include; limping and favoring, laying on side (way) more than usual, respiration of 106, teeth grinding, and quiet squeaks from certain movements. I don't have a thermometer, but his food and water intake are okay and his urination/defecation seems to be returning to normal. Elmer (bunny) would be very appreciative for your help. I would appreciate it too.
