Safety First.

  • advantus™ is the first FDA-approved soft chewable flea treatment for dogs. Because it’s available without a prescription, it’s designed with your dog and your lifestyle in mind. You can treat immediately when you see fleas on your dog. Because adult fleas may be an indication of a flea infestation in your dog's environment, you might have to retreat your dog until you have addressed the flea infestation in your home or yard. advantus™ was designed with flexibility in mind so you can safely use up to 1 soft chew per day because the active ingredient quickly dissipates in your dog's system.

    If your dog has food allergies, it's safe for them, too — because advantus™ is not made with animal protein. With advantus™, you can rest easy knowing your dog's flea treatment is safe — and starts working fast.
