I am DEAD certain that my puppy has fleas. My boyfriend said he saw small black bugs on him after playing outside. He is always scratching or something. When we take him to the vet, the vet says she sees no fleas or flea dirt. I want to just give him something to be sure. I would hate the thought of fleas in my house.

I feel like I’ve tried just about everything! Both Frontline and Advantix don’t work on my dog’s fleas, so I’m looking for something that might. Thanks!
Just so you guys know, I was putting this Advantage on monthly. I have always been very particular about putting their topical on the same day every month, as well as giving them their heartguard. I just wanted to let everyone know that since some thought that I was just being careless with it. Thanks.
