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)

Recommend

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.

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.
