I like that the scent is not offensive and it is all natural. You have to be careful what you use on your dogs because they can be sensitive to some of the products they sell at the pet stores. I would try a little at a time to see if they have a reaction. If it seems fine then do as much as directed. Dogs are in and outside of the house so it is hard to completely get rid of fleas. You at least narrow it down to less.
