Monthly treatments are required for optimal control and prevention of fleas and ticks. The dog should be standing for ease of application. Part the hair at your dog's shoulder blades to expose the skin. Apply product evenly and directly to the skin in two to six spots along the dog's back by squeezing out the tube's entire contents. Your dog's natural movements will help spread K9 Advantix II over the skin. K9 Advantix II remains effective after swimming or bathing (use a non-detergent-based shampoo).

Rated 5 out of 5 by Great Product This year was the first time in years I have had fleas after using a couple other brands I bought this online. This product worked great! Within a day my dogs were free from bugs. Excellent!!! January 21, 2017

Rated 5 out of 5 by Love my products healthy and my dog is satisfied Won't order anyplace else very satisfied with the products and overall service the customer service is very knowledgeable and perfessional my products always delivery on time January 16, 2017
Rated 5 out of 5 by My favorite flea and tick med! This is the only flea and tick medication I buy. I think it's the best. I like that not too long after it's on, it drys and absorbs so your dog doesn't have a greasy spot on their neck. Some of the other flea and tick medications leave that greasy spot for a day or two. My two shih tzu's are flea and tick free! January 13, 2017
Rated 4 out of 5 by The price is right for this product. Hoping this product will get rid of the fleas!! I have used similar products before and this one is easy to use. Compared to the local vet's product it is half the price. January 10, 2017
Rated 1 out of 5 by No expiration date I buy this product all the time. I bought 2 boxes because price, however there is no expiration date. So i don't know how effective it will be. Each month i apply it i don't know if it will work. December 24, 2016
