    I have used Biospot on hundreds of dogs over the past 15 years and it has always worked great!! I have not ever seen a product that works as well consistently.

    "New bad/old was the best"

    I too have used Bio-spot since the first on the market, l also referred to my clients. NOT ANY MORE... l use to order the groomers package (100 in the box)even when they stopped selling the groomers package, l would purchase 6 or more 6 months supply all year long.. never again.. it doesn't work any more.

    "Worst Ever!!"

    This was an expensive mistake! Not only has Biospot charged more for the plastic thing that doesn't work to snap off the cap, this product is useless to kill anything. I have used Biospot for yrs. but this is not the same formula and does nothing for fleas or ticks. It should be taken off the market. DO NOT WASTE YOUR MONEY on this product!!

    ""New"" formula, bad results""

    If I could have given this a big fat 0 I would have. Sorry Bio spot, your new formula is worth about that... nothing. It is greasy, sopping, messy and worst of all it does NOTHING to stop ticks. We don't have a flea infested area so I can't comment on that, but I expect it would not work on them either. I used this product for over 10 years and will NOT be going back. K9 Advantix here I come!

    "New formula"

    The new formula is too thick and is hard to get much of it to the skin. Most of it ends up on their hair and makes them look all greasy. Have switched to an easier product to use and more effective.

    "BioSpot Defense"

    Doesn't work. Don't buy this product. I want the old Bio spot.

    "Doesn't work for my dogs"

    "I agree that the ""old biospot"" worked but the biospot I have now doesn't kill fleas at all for my dogs. They are scratching and I am picking fleas off them. I am having to order a different brand of flea medicine now."

    "I want the OLD Bio Spot"

    "I have been buying Biospot for years. I have 6 rescue dogs, Biospot has been wonderful. However this ""new"" product they have seems to work at first but only for a week or two- after just days my dogs are itching and full of fleas- I am now searching for a new product :( I wish I could buy the ""old"" biospot!!!!"

    "Works fine on farm"

    I've been using BioSpot for our dogs and cats, and EquiSpot for horses (to repel flies and kill ticks, etc.) for years. I mark the application date on the calendar so I don't forget to reapply them. These products have been 100% effective. I tried a couple of the more expensive products, but they didn't work any better, so I'm sticking with BioSpot.

    "Not Worth It"

    This product worked at the beginning of the season but now that its full on flea and tick season my dogs and cat are infested. From now on I'll be spending more so I never have this problem again :(
