Rated 4.1 out of 5 by 695 reviewers.
Rated 5 out of 5 Excellent product I've used Advantix II for several years on my cats and dogs. It works better than anything else I've tried. With the extra 20% it was cheaper at petcarerx by about $8 than anywhere else online. Shipping was very fast. August 30, 2014

Rated 5 out of 5 by PETCARERX IS VERY RELIABLE THIS PRODUCT IS INSANELY EXPENSIVE NO MATTER WHERE YOU LOOK. PETCARERX HAD IT AT THE MOST AFFORDABLE WHICH IS WHY I USE THEM.

Rated 1 out of 5 by Product Does Not Work I started using K9 Advantix II this summer. I've had to treat my 15 pound dog every 2 weeks and he's still infested with fleas. My dog has never had fleas this bad until using this completely ineffective product. Do not recommend. August 14, 2014
Rated 5 out of 5 by This product works. We live in tick infested arer with lots of wildlife including deers. This product keeps our dog free of insects. Not one tick on him this year. August 11, 2014
