Overview

Advantage II Medium Dog delivers a veterinarian‑recommended topical treatment for fleas, designed for dogs weighing 11 to 20 pounds and at least 7 weeks old. It targets fleas at all life stages—adult fleas, larvae, and eggs—providing a comprehensive approach to flea control for your dog and home.

Fast-acting, long-lasting protection

Fleas begin to die within 12 hours of application through contact, helping your dog stay comfortable without bites. The protection lasts for 30 days, supporting ongoing flea control as routines and environments change.

What makes it convenient

  • Kills adult fleas, flea larvae, and flea eggs for total flea prevention
  • Easy-to-apply topical treatment with no prescription
  • Fragrance-free formula and becomes waterproof after 24 hours
  • OTC product, suitable for indoor and outdoor dogs

Real-life use cases

Ideal for dogs that swim or roam outdoors, or homes with multiple pets seeking monthly protection. A simple single‑application routine can fit into busy schedules and active lifestyles.

Important notes

  • Designed for dogs weighing 11–20 lbs and at least 7 weeks old
  • Follow the label for exact application instructions and potential side effects
  • Consider a subscription for regular doorstep deliveries to never miss a monthly treatment

What to expect after application

After application, your dog can return to favorite places—backyard, park, or trail—while flea protection works in the background.

If you’d like ongoing, predictable protection, a subscription option helps keep your routine consistent and hassle-free.
