Advantus MOA video script

No one likes to see their dog infested with irritating fleas. Fleas not only cause discomfort. They may also transmit disease-causing organisms to your dog.

That’s why it’s important to treat as soon as you notice fleas on your dog. Advantus imidacloprid soft chews are available without a prescription and are indicated for the treatment of flea infestations on dogs and puppies 10 weeks of age and older and weighing 4 pounds or greater.

To give Advantus, simply place the soft chew directly in your dog’s mouth or allow the dog to take it from your hand. Once your dog ingests the soft chew, the active ingredient, imidacloprid, spreads throughout your dog’s body. When fleas feed, imidacloprid over-stimulates the fleas’ nervous systems, resulting in the fleas’ death.

Advantus starts to kill fleas within 1 hour, and achieves greater than
96 percent effectiveness in just 4 hours.

Because Advantus does not have an effect on fleas in the environment, your dog may become re-infested. You can safely repeat treatment as often as once a day.

Be your dog’s hero with fast-acting Advantus.
