Once K9 Advantix II is applied, your dog is ready to get right back to the things it loves most. K9 Advantix II pest protection is effective on both indoor and outdoor dogs. Your dog should be at least 7 weeks old and weigh 4-10 lbs. to use K9 Advantix II Small Dog. K9 Advantix II Small Dog is a trademark of Elanco or its affiliates.

My veterinarian recommended this for my pug. I have been very pleased with it. I have not seen any fleas on my dog or in my house.
