Product Description

Advantage II Medium Dog is the vet-recommended prevention and treatment of flea and lice infestations in dogs. Advantage II Medium Dog flea treatment and prevention kills adult fleas, flea larvae and flea eggs to deliver total flea protection to your dog or puppy. In fact, within 12 hours of application, Advantage II Medium Dog topical treatment gets straight to work killing fleas through contact, so they don’t have to bite your dog to die.

This 30-day treatment effectively breaks the flea life cycle, controlling existing flea and lice infestations and preventing further infestations all month long. Fleas not only cause discomfort; they can also pose other health risks. Monthly use of Advantage II Medium Dog is important to protect your dog against fleas that may cause transmission of tapeworms in dogs, Flea Allergy Dermatitis and flea bite anemia.

That’s why Advantage II topical, spot-on formula makes application simple - going on in seconds. It's easier than a flea collar and there are no hard-to-swallow pills. You’ll also love that Advantage II is fragrance-free and waterproof after 24 hours of application. Check the product label for information on application and potential side effects.

Advantage II Medium Dog flea and lice protection is effective on both indoor and outdoor dogs. Your dog should be at least 7 weeks old and weigh 11 to 20 lbs. to use Advantage II Medium Dog.

For the ultimate convenience in care, Advantage II Medium Dog is available over the counter – no prescription needed. And, you can stock up with a subscription for regular doorstep deliveries so you never miss a monthly treatment. Once Advantage II Medium Dog is applied, your dog is ready to get right back to exploring his favorite places – from the backyard to the dog park.

Advantage II Medium Dog is a trademark of Elanco or its affiliates.

Outside box was opened on last 2 orders
Advantage II is the best flea prevention I've found for my dogs. Amazon is the best place to order it as far as price and convenience. My only complaint is the last 2 boxes I've ordered have been open on the outside. I would be more concerned than I am but the inside pouches are safely sealed so I guess it's something that happens in transport. Maybe the boxes are too flimsy or they're not packaged carefully enough.
Thank you for your feedback
