Today’s Pet meds Spotlight is on the flea preventative Advantage. Advantage is a monthly flea preventative for dogs and cats that offers complete flea protection by killing adult fleas, larvae, and their eggs. Advantage also treats, and prevents, lice on dogs. Advantage does not kill ticks, but as with all medications, you should try to use as little as possible to attain the desired results. Depending on your area, ticks may not be an issue. But if a problem with ticks does occur, we recommend using the Preventic Tick Collar along with Advantage.
