How Do You Find the Right Rimadyl Dosage for Your Dog?

Dispense 2 milligrams of Rimadyl per pound of the dog's weight daily, according to 1-800-PetMeds. The total dosage can be given once daily or divided in half to be administered twice daily.

For a 70-pound dog, the owner should provide 140 milligrams of Rimadyl daily based on the 1-800-PetMeds dosage formula. The medication, which is well-tolerated by dogs, should be given with food, with plenty of water available. Rimadyl is available in a chewable tablet and non-chewable caplets; both are available in 25 milligram, 75 milligram, and 100 milligram dosages. 1-800-PetMeds requires a prescription from a licensed veterinarian to purchase Rimadyl.
