Is 12.5mg Rimadyl every 12 hours a safe dose for my 10 lb dog?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 12 years and 6 months old | 10.34 lbs

Is it okay to give my 10 lb dog 12.5 mg of Rimadyl every 12 hours? I can’t figure out how to cut the 25 mg pill into 3rds; plus it would then give only 8 mg. And I want to make sure she gets relief. If the blood work comes back normal, should I not worry about the 12.5 mg every 12 hours? Thank you for your time and help!

Hello! The 12.5mg every 12 hours is appropriate for her size as long as her bloodwork comes back fine. I couldn't cut a pill into thirds either- that's too hard! I hope you find this helpful. Thanks for using Petco Pet Education Center, formerly Petcoach!
