Two things; now Walmarts carries Adams flea meds It's just like frontline but it works; the second get your self some Simple Green and bathe your dog in it; it kills the fleas and like for my dogs I makes thier white fur really bright. I've been bathing dogs in it for over 20 years and it works great. It's right in the cleaning isle. I mix it 1/2 & 1/2 with water and put it in a spray bottle for pre-treating clothes; gets oil stains out.
