AdvantageGreen 4 monthly Doses For Dogs Up To 10 Pounds USA / EPA

I stopped using this for a few months since it was so expensive, then my dog started scratching all the time, and all members of my family got flea bites. It was a pain to bug-bomb the house, spray the cars, Give the dog flea baths, vacuum daily, wash everything....So I purchased more of this, even though it seemed high priced. Life is good again, we are no longer flea infested. Fleas prefer to go on my dog instead of me, they bite the dog and die.

Bought for a friend, is the only thing that works on her yorkie.
