How do I know the dosage of pain medication for my dog? - Compassionate Care Veterinary Hospital

We calculate the dose, usually by body weight, and then we figure out how long the pet needs it. Is it more of an acute injury or more of a chronic, old-age type of deal where we're treating some osteoarthritis or something like that? Your veterinarian will calculate that dose based on those factors.
