The Advantus Flea Control Soft Chews for Small Dogs are a fast-acting treatment of flea infestations. Advantus flea treatments for dogs start killing fleas within 1 hour with just a single dose. In the event of continued infestation, you can repeat treatment with small dog flea soft chews as often as once per day. These flavored soft chews are for dogs and puppies 10 weeks of age and older. You can treat immediately when you see fleas on your dog. The Advantus soft chews for small dogs were designed with flexibility in mind, so you can 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. These flavored soft chews can be used together with heartworm preventatives, dewormers, shampoos and antibiotics. Warning: Not for human use. Keep this product and all drugs out of the reach of children and pets.
