Question: how much imodium for a 25 lb dog?
Answer: According to veterinarian Dawn Ruben via Pet Helpful, “the dosage of Imodium is 1 Imodium capsule (2 mg) per 50 pound dogs.” You can cut the tablet in half for 25-pound dogs. The liquid form of Imodium is better suited for dogs that weigh less than 20 pounds since it allows for smaller dosages.
