In choosing a heartworm/flea med. at what point do I go from puppy meds to adult meds. My puppy Sara is a rott/boxer/blue tick hound mix she is 7 months old and weighs approx. 50 lbs. Can you suggest a product that will be effective. Thank you for your time.
Most of the products go by weight, not puppy vs adult. Try Sentinal or Revolution. Vetcare
