Protect your 11–20 lb dog from fleas with Advantage II

Advantage II Medium Dog offers vet-recommended flea prevention and treatment for dogs 11 to 20 pounds and at least 7 weeks old. It targets adult fleas, flea larvae, and flea eggs to deliver total flea protection for a full month.

Fast, visible results

Within 12 hours of application, fleas start to die on contact, which means your dog can stay out of discomfort sooner. The product continues to work for 30 days, helping to break the flea life cycle and reduce the chance of re-infestation.

How it works

  • Kills adult fleas on contact without requiring fleas to bite your dog
  • Targets flea larvae and eggs to interrupt the lifecycle
  • Fragrance-free formula suitable for sensitive dogs
  • Waterproof after 24 hours to handle rain or baths
  • Easy, one-step topical with no prescription

Convenience and peace of mind

Designed for indoor and outdoor use, you can apply Advantage II Medium Dog quickly and confidently. It is OTC, so you can stock up through subscriptions for regular doorstep deliveries, ensuring you never miss a monthly treatment.

Note: Always check the product label for application details and potential side effects. Results can vary by individual dog, and continued use is advised for ongoing protection.

With Advantage II, you can keep playing with confidence—from the backyard to the dog park—knowing your dog has a practical, fragrance-free defense against fleas.
