## Description

K9 Advantix II Small Dog is the veterinarian-recommended formula that helps defend your dog against five pests: fleas, ticks, mosquitoes, biting flies and lice. And unlike other treatments, K9 Advantix II kills and repels fleas, ticks and mosquitoes. K9 Advantix II topical treatment gets straight to work killing fleas on dogs within 12 hours of initial application. This formula stops existing flea infestations and prevents new ones by killing adult fleas on contact so they can’t lay eggs and they don’t have to bite your dog to die. Fleas, ticks, mosquitoes and other pests not only cause discomfort; they may also transmit disease. Monthly use of K9 Advantix II is important to protect your dog against fleas that may cause transmission of tapeworms. This formula also kills fleas which may cause Flea Allergy Dermatitis and flea bite anemia. That’s why K9 Advantix II Small Dog topical, spot-on formula makes application simple - going on in seconds. It's easier than a flea collar and there are no hard-to-swallow pills. You’ll also love that K9 Advantix II is fragrance-free and waterproof after 24 hours of application. Check the product label for information on application and potential side effects. 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. For the ultimate convenience in care, K9 Advantix II is available over the counter – no prescription needed. And, you can stock up with 2-dose, 4-dose and 6-dose packs so you never miss a monthly treatment. Once K9 Advantix II is applied, your dog is ready to get right back to big-pup cuddles and racing around the park. K9 Advantix II Small Dog is a trademark of Elanco or its affiliates.

## Questions & Answers

**Q: can k9 be used on puppies 8 weeks old  she  keeps biting her side  like something is there**
A: I would try giving the puppy a bath with Dawn liquid soap and talk to you local vet about giving this to your new puppy

**Q: Do u have one for Poodles 21 23 lbs.**
A: Use Frontline or Advantage. Advantix does not work as well.

**Q: Can anyone in florida give me your opinion on it’s effectiveness? i’m told that the fleas in fl are developing a resistance to some treatments.**
A: I live in the Tampa Bay area in Florida and used this on my chihuahua for over 3 years and it has been very effective.  I do not give him heart worm treatment since it repels and kills mosquitos as well and every time the vet has done his heart worm test, it has been negative.  Therefore, I highly recommend this product, not only for fleas, which he has never had but for mosquitoes as well.

**Q: Delivery on6-28?**
A: Hi. Unfortunately, we’re not able to answer this question. We recommend you contact the seller for more information.
