Advantix II

I have been using the Advantix II since its inception. Because we live in a Forest with wildlife abound, this product is essential for keeping our canines free of fleas %26 ticks. I use it year round as our area is never cold enough to kill all pests. (This product is also recommended by our Veterinarian)

Best Flea and Tick protection, Best price

We have used Advantix II on our Springer Spaniels, and have never had any problems at all with fleas or ticks. We live on a mountain in PA, and the dogs are outside with us a lot, and we don't have to worry. We also have ponds, and there is added protection from mosquitos. Great product and with in store pick up from Walmart you can't beat the deal.

Amazing product really works

I've used frontline plus four years with good results until this year. After trying several other products that hasn't worked I had to find something that did. My yorkie has flea allergies and was constantly scratching and had to be put on predizone! I went online and found the best rated flea product was k9 Advantix II, within 12 hours of application I only found one dead flea on my yorkie and none on my sheltie! Dogs are happy and mamas happy. I redose them every three weeks as the box directions reads you can. This seams to have put a stop to our flea problem! And my yorkie no longer needs prednisone for flea bites. Hope it works as well on your pets.
