Thanks everyone, I had been using the Bayer and dominion, but seemed like the fleas were building a tolerance. On grown dogs I use 3 cc right down the back, so for the price to ratio used on a dog you can't beat it. I think I'm going to use this stuff for 3 months then switch back to the dominion for 3 months. Try to keep anything from building up a tolerance. Thanks again for all the input.
