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.
I worked up the calculation fir the dominion and bayer...I used a different brand...but the active ingredient is 1.47%...if that is what you have then you need to use 12 to 15 cc's (mils)...that will work on a 40-60 pound dog...when I used it that is the amount I used...ran some along the top line and rubbed some on the belly...
