Safety First.

  • advantus® is the first FDA-approved soft flea chewable 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. advantus® soft chew was designed with flexibility in mind so you can safely use one chew per day because the active ingredient quickly dissipates in your dog's system.

    If your dog has food allergies to ingredients like chicken or beef, advantus® is a suitable option because it does not contain any animal protein. With advantus®, you can rest easy knowing your dog's flea treatment is safe — and starts working fast.
