My groomer recommended the K9Advantix because I was having no luck with the oral flea treatment. I live i a very dark wooded area and it has been extremely wet this spring. Fleas are thriving. But my dogs so love to run in the yard and especially while I am in the garden. In less than two weeks my two small dogs and the house are flea free. VERY PLEASED.
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.

worked fast
I gave this a try because the veterinary was to expensive $65 a pill plus for each of my 3 dogs, that's out of the question. This however worked fast within and hour I could see the fleas seemed sick and by the afternoon there were no fleas on any of my dogs I recommend this product.
