Too heavy to hold? Your vet will weigh them if you ask (or may already have it on file if you call).

Rated 4.5 out of 5 by 603 reviewers.
Rated 5 out of 5by Great product!I have been using k9 Advantixll on my dog for 2 years! I have never seen a flea. Keep up the good work. I like the fact that k9 Advantixll repels and kills fleas, ticks and mosquitoes and it is waterproof! 02/22/2018
Rated 5 out of 5by no odorno odor (unlike other products), no fleas! 12/11/2017
Rated 5 out of 5by This product works well. If we find a flea on the animals when they come in from outside, the flea is usually acting sick from the K9 Advantix II or is dead. 07/19/2016
Rated 5 out of 5by Works on mosquitos This is the only flea and tick topical that also works on mosquitos. I highly recommend this product. I have been using it on my dog for 14 years. 07/04/2016
Rated 5 out of 5by Good stuff I started using this product on my boxer, Nikki about a year ago. I have never noticed fleas on her when applied or ticks. If I do find a tick, it hasn't set in on her yet. I bought a "less expensive" product a few months back when I ran out of K9 Advantix and I was so sorry. She got fleas...within 2 weeks of applying the cheaper version. Never again. She's worth every penny. 07/01/2016
Rated 4 out of 5by Good stuff! I've never seen a flea or tick on any of my dogs using this product. 06/28/2016
Rated 1 out of 5by Waste of money This product d d not work at all. Good thing I didn't order the 6 month supply! 06/16/2016
Rated 5 out of 5by This product was at a great value. I am very pleased with the prices and the delivery of my product. I will be using PetCarRx in the future and will be recommending it to my friends and family. 06/11/2016
Rated 5 out of 5by Excellent Product To Use I use this every month for control of fleas and ticks & mosquitos on my dogs. It works and I have no problems with any conditions on my dogs, no fleas, no ticks and no mosquitos bites! It is extremely easy to use and apply on my dogs. I highly recommend it, and one application last a month. 06/03/2016
Rated 2 out of 5by Not nearly as effective against ticks Ticks are not being repelled or killed by this but it is still effective against fleas. 06/03/2016
Rated 4 out of 5by Works better on ticks than the competitors Ticks are our biggest problem. Our dog goes in the woods a lot and tends to pick up ticks. Advantix II seems to work better than the other products on the market. 05/30/2016
Rated 5 out of 5by Easy to useWe have used K9 Advantix II for Dogs for years and we highly recommend it, our pets have not had any problems with fleas or ticks. 05/23/2016
