One option for administering Human Grade Herbs to Dogs is applying the Clark's Rule.
Clark's rule is a medical term referring to a mathematical formula used to calculate the proper dosage of medicine for children aged 2–17. The procedure is to take the child's weight in pounds, divide by 150 lb, and multiply the fractional result by the adult dose to find the equivalent child dosage. This same formula has been successfully applied to dogs. Use at your own discretion.
