What are the active ingredients in K9 Advantix II?

K9 Advantix II is one of the most popular and effective flea and tick prevention products or dogs now available.

K9 Advantix II contains three active ingredients: Imidacloprid, Permethrin, and Pyriproxyfen.

K9 Advantix should never be used on cats. Permethrin is toxic to cats. Always buy a cat specific flea and tick treatment for your feline friend.

Most other products wil use one or two ingredients. The combination of three ingredients in K9 Advantix II makes it effective for preventing and killing many types of parasitic insects that can be cause distress to your dog:

  • Ticks
  • Fleas
  • Mosquitos
  • Lice
  • Biting Flies

K9 Advantix II kills all living insects of the above types when they are on your dog.

It also kills flea eggs and flea larvae on your dog, eliminating the next generation of fleas and breaking the cycle of flea infestation.

K9 Advantix II is a simply monthly spot-on topical treatment that’s fast and easy (and stress free) to apply to the back of your dog starting at the shoulders, and continuing in a spot pattern down to the base of the tail, directly on to the skin with the fur parted.

It eliminates the need for having to use an oral tick treatment.

The formula is designed for all dogs aged 7 weeks and above. Do not use K9 Advantix II on pups younger than 7 weeks.

Imidacloprid, Permethrin, and Pyriproxyfen are the active ingredients in K9 Advantix II.

These active ingredients make up just over 53% of the K9 Advantix II formula.

The remaining almost 47% consists of other inactive ingredients. This means they don’t contribute the prevention actions of K9 Advantix II and have no effect on your dog. They are included in the formula for reasons such as coatings, preservatives, or to allow the formula to be used in a spot-on method. Inactive ingredients are used in just about every medicine in the world, and are not something to be concerned about.
