Advantage is a monthly, year-round treatment to protect your dog against fleas and the problems associated with fleas. Fleas not only cause itchiness for your dog -- and you -- but flea bites can lead to skin infections, allergic reactions, and other problems.
Advantage stops biting fleas in 3 to 5 minutes, starts to kill adult fleas within an hour after it is applied, and kills 98 percent of fleas within 12 hours.
