Frequently Asked Questions
How long does it take to work on fleas?
Advantage II for dogs kills fleas within 12 hours of application.
How does it work?
Advantage II for dogs is a topical flea treatment that spreads over the skin and hair. Advantage II kills through contact, so fleas don’t have to bite your dog to die. With oral flea treatments, fleas must bite your dog and ingest the medication before they are killed.
How do I apply Advantage II topical flea treatment?
Be sure to use the entire tube of Advantage II when applying it to your dog. Part the hair on your dog’s back between the shoulder blades until the skin is visible. Squeeze the tube to expel the entire contents directly on the skin in 1-4 spots, depending on your dog’s weight. See package insert for additional details.
Why do I still see fleas after using Advantage II?
The fleas you see on your pet today are not the same fleas you initially saw when applying the treatment. These are new fleas from the environment that have since developed into adults and jumped on your dog. As the weeks go by, these developing stages should run their course and disappear. Be sure to treat your pet’s environment, including your home, yard, carpet, bedding, etc.
Does it expire?
There is no expiration date required on the packaging by the EPA for Advantage II for dogs. The product should be kept in its original packaging and stored as directed on the label.
What are the key ingredients?
Advantage II for dogs contains two active ingredients: imidacloprid, which attacks the flea’s nervous system, to paralyze and kill it, and pyriproxyfen, which prevents eggs and larvae from maturing.
