Heather says...Treated all my dogs, they all still have fleas a week later.
Liesa says...I have used this product on my boy since he was a pup
I have never seen a flea on him
Maybe we are lucky
Anna says...I applied Advantage as suggested but 3 days later, he still has some fleas. The entire area he lives in has been thoroughly cleaned, and there are no other pets he has been in contact with, so he could not have been reinvested.
