K9 Advantix II – Flea, Tick & Mosquito Treatment for Extra Large Dogs (6 Doses)

For Dogs Over 55 lbs | 7 Weeks or Older | Waterproof | Monthly Topical Treatment

Protect your dog with K9 Advantix II, a vet-recommended topical formula that kills and repels fleas, ticks, mosquitoes, biting flies, lice, flea larvae, and eggs — all in one easy monthly application.

Why Choose This Product?

  • 6 Monthly Doses: Long-lasting protection for 6 months.

  • Fast-Acting & Waterproof: Starts killing fleas within 12 hours and stays effective even after bathing or swimming.

  • No Bites Needed: Repels before pests bite — helping prevent disease transmission.


How to Use:

  1. Part your dog’s fur between the shoulder blades.

  2. Apply the entire tube directly to the skin.

  3. Use once every 30 days for continuous protection.


Ideal For:

  • Dogs over 55 lbs

  • Dogs 7 weeks or older

  • Owners looking for hassle-free, collar-free pest prevention

⚠️ Do NOT use on cats. Keep out of reach of children.


How It Works:

K9 Advantix II uses three active ingredients:

  • Imidacloprid – kills fleas

  • Permethrin – repels and kills ticks, mosquitoes, and biting flies

  • Pyriproxyfen – halts flea development (eggs & larvae)

Together, they provide broad-spectrum protection that interrupts the flea life cycle and prevents re-infestation.


Give your pet the protection they deserve — with K9 Advantix II, parasites don’t stand a chance.
