Q. What is the dose of ivermectin in heart work preventive for dogs 50-60 lbs
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. Dr. Pugh's answer below is correct. The reason we cannot provide you with dosing information for ivermectin is that it is a prescription drug and in order to give prescribing information the veterinarian must have performed a physical examination on the dog. Ivermectin is very easy to mis-dose, and it is contraindicated in herding breeds such as border collies. Therefore my best recommendation is for you to visit a vet who can examine your dog and make dosing recommendations.
DR. EVE PUGH, DVM, CVA
