I hope it works better for you than it did for me.

I bought it a couple of years ago for my dogs - and they got fleas - BIG TIME!!!!

I got a refund from Dr Foster & Smith on it, but it cost me in the long run. Since my dogs are highly allergic to fleas, I had to take them to the vet for a pred shot, and then ended up buying the Advantix that I had them on originally. Then I had to buy a flea killer spray for the furniture and carpets. That whole fiasco cost me a lot more than the money I saved by buying the Bio Spot.

I now get their flea med from vetshoponline.com. They are very inexpensive and carry all the major brands. They ship from Australia and their shipping is only $4.95, no matter how much or how little you buy.

You should check them out!
