Not sure which site you got that from or who wrote it but 10% is to strong to put directly on a dog. If you are going to use it in that manner, and I am not recommending it, it would be 12 CC of 10% mixed with 8 oz. water for a 0.5% final solution. The best thing for fleas is Bayer tree and shrub insect killer. I use 1-3 cc starting at the neck and going to the tail.
