Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.



About Advantage II Dog

About Advantage II Dog

Help stop the misery of biting fleas with Advantage II. This vet-recommended, monthly topical formula works to kill adult fleas as well as flea larvae, eggs and lice, so your pup is ready for fun. Plus, it's for dogs and puppies 7 weeks of age or older. Help your pal get the effective protection he needs by experiencing Advantage II.

Why Choose Advantage II?

Advantage II is fragrance-free, odorless, waterproof after 24 hours of application and kills fleas directly through contact. That means pesky fleas don't have to bite to perish. With just one application, you can prevent further flea infestations for up to 4 weeks and can even help prevent, control and treat lice infestations. With Advantage II, you can stop multiple flea life stages, effectively breaking the flea life cycle.

Help Break the Flea Life Cycle

Immature fleas in a pet's environment consist of around 95% of an infestation and can be nearly invisible to the naked eye. That's why Advantage II has two active ingredients that work to stop fleas in their tracks. The first active ingredient kills fleas by targeting their nervous system, while the second works as an insect growth regulator that kills flea eggs and larvae.

Is Advantage II the Right Choice for Your Dog?

Whether your dog is a winter snow hound or a summer backyard explorer, an indoor sun seeker or an outdoor enthusiast, choose Advantage II to help keep fleas from interrupting his favorite activities year-round. If you want to return the love to your dog, take care of him with flea prevention that works to kill the fleas you see and the ones you don't.

Only one that works for us

This is the only one that works for us (we live in the country). Everything else is like a squirt of water on our dog. Super fast shipping from Chewy is always a big plus, too!

Wrong product

Thought I ordered Flea and Tick , but received flea only. Will what I have also kill ticks ? If not, can I return what You I have and get flea and tick ? If so you have my credit card. Ship what I need and I will send back the other in the box you send. Probably need a RA. Thank you.

Cheaper than in-store prices!

I've been having such a hard time finding this product on shelves in stores near me, and when they have it the right dosage for my dog costs almost $60. I've used this brand on my dog since she was a puppy (after she was old enough to use this product) and it has worked for us so well, and the application is super easy as well!
