“I have a 100 lbs Doberman that is an inside dog. However goes outside just as often an have never once seen a flea on him! He is 5 years old. He has had the medication for years now. I don't ever allow him to go without it. I couldn't imagine how disgusting my home would be without this medicine! It would be full of fleas. I seriously have never seen one though. On him or in the house! Great product!”
