This product is specifically formulated for medium-sized dogs weighing 11 to 20 pounds.

How does K9 Advantix Medium Dogs 11-20 Lbs (Aqua) 6 Doses + 2 Free compare?

Compared to generic flea and tick treatments, K9 Advantix offers broader protection, including mosquito repellency—a feature absent in many standard polypropylene-based or fipronil-only products. It outperforms over-the-counter collars and shampoos in duration and efficacy. Unlike oral treatments that require digestion, Advantix works topically and starts killing pests faster. However, it contains permethrin, which is toxic to cats, making it less ideal for multi-pet households than cat-safe alternatives like NexGard or Bravecto.
