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. Review: Good product - I have a small puppy who had fleas at 6 weeks old. I had a difficult time finding flea medicine that was safe for such a small dog. This worked well. Review: Great value and it works as presented - So far so good on minpin 10 year old service dog. No hypersensitivity issues. Easy to apply. I usually apply it and crate her for an hour while it dries. No bugs! Good value too, nice for in between veterinary Revolution Drops that include heartworm prevention. ## Features - K9 Advantix II Small Dog 30-day treatment & prevention protects dogs 4-10 lbs. from fleas, ticks, mosquitoes, biting flies and lice - Kills fleas within 12 hours of application - Vet-recommended formula kills & repels on contact so fleas don’t have to bite your dog to die - Easy-to-apply topical treatment is fragrance-free and waterproof after 24 hours - No prescription needed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00I0BXQ6Q | | Active Ingredients | Imidacloprid, Permethrin, Pyriproxyfen | | Age Range Description | 7 weeks and older | | Allergen Information | Allergen-Free | | Best Sellers Rank | #1,119 in Pet Supplies ( See Top 100 in Pet Supplies ) #14 in Dog Flea Drops | | Brand | K9 Advantix | | Brand Name | K9 Advantix | | Customer Reviews | 4.3 out of 5 stars 19,046 Reviews | | Dog Breed Size | Small | | Global Trade Identification Number | 00724089060556 | | Item Form | Topical | | Item Type Name | Topical | | Item Volume | 0.8 Milliliters | | Item Weight | 18.14 g | | Manufacturer | Elanco US Inc | | Manufacturer Part Number | 86314878 | | Model Number | 86314878 | | Scent | Unscented | | Scent Name | Unscented | | Target Species | Dog | | UPC | 724089060556 | | Unit Count | 2 Count | | Volume | 0.8 Milliliters | ## Product Details - **Active Ingredients:** Imidacloprid, Permethrin, Pyriproxyfen - **Age Range (Description):** 7 weeks and older - **Allergen Information:** Allergen-Free - **Brand:** K9 Advantix - **Dog Breed Size:** Small - **Item Form:** Topical - **Item Volume:** 0.8 Milliliters - **Item Weight:** 0.04 Pounds - **Scent:** Unscented - **UPC:** 724089060556 ## Images ![K9 Advantix II Small Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs 4-10 lbs. | 2-Mo Supply - Image 1](https://m.media-amazon.com/images/I/71vHmvPM6hL.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by J***N on April 23, 2026* I have a small puppy who had fleas at 6 weeks old.
