Works great
It's been almost 24hrs since I applied it and the fleas are just falling off my dog either dead or dying. No Frontline product has ever worked on my dog but this one works great. So glad I found it.

Does not work as well as the monthly pills!
It's works, but not nearly as good as had hoped ! Effective for about 15 days !

DO NOT WASTE YOUR MONEY
I just wasted $175 on this product. After reading reviews and doing research I decided to try it. NEVER AGAIN! It didn't even touch the fleas. I will be going back to Advantage!. Just wish I could get my money back!
