    I have been using this flea product for a number of years and my dog has never had any trouble with fleas. Excellent product at an excellent price. This product is a lot cheaper than anywhere else.

    Did you hear about the 2 fleas that won the lottery?

    They bought a dog in Spain.

    Good Stuff !!!
    Have used this for years, with several dogs and have always been pleased that it has protected my dalmatians from ticks and fleas and living in a rural environment this is important. Would happily recommend it.

    Advertised as 3 boxes but only one delivered. I am still awaiting a resolution to the error.
