Although I do admit I'm glad our pooch's meds - her heartworm pills - taste good to her. She thinks it's a special treat. Not so much with the flea-ointment but she tolerates it at least.
My pups love the heartworm stuff too. I put the flea/tick stuff on them first, then give them the heartworm med. They tolerate getting the flea/tick stuff for the heartworm med. Win-win!
