    I use this product on my dog to keep the ticks and fleas under control. My dog doesn’t have contact with wooded areas. He is spoiled and primarily stays indoors; he is a large dog with longer hair. We have a large wooden deck in our back yard and see at least 2-3 bunnies in the neighborhood daily. Our back yard has full sun with very little shade which used to be a blessing because the ticks were never seen. This year has been different. I have seen ticks on my fence in my own backyard, on my neighbor's dog and to be honest found one on my dog. I realized that I didn't apply the product yet for this year so I applied it last month. I have not seen a tick on my dog since. Thank you K9 advantix II.

    I don't know if I got a bad batch of this product or what the problem is, but it didn't work. At all!!! I used it on 3 different breeds (Cocker Spaniel, Yorkie, and German Shepherd.# It never did get rid of all of their fleas, and within one week, they were ALL a mess - fleas everywhere! Purchasing this product should give the owner piece of mind, especially since you all got a big piece of my bank account to pay for this product for 3 pets!!) and instead, it brought about frustration and even MORE expense #had to purchase other products) We also threw away all bedding, because the problem took so long to solve and we didn't want to take any more chances. We treated the house, the yard, the pets, and all their bedding, and we still had a problem with fleas. And, yes, we used it exactly like the label recommends. Horrible experience, and lots of money spent!! I will NEVER purchase this product again!

    Easy application to apply to dog and soaks in 24hours. Like that it has biting insects added to fleas and ticks. More coverage over mosquitos to help in preventing heartworms.
