This fragrance-free formula requires no prescription and offers fast, easy monthly application to keep your dog pest-free and comfortable. ## Description K9 Advantix II Medium 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 Medium 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 11-20 lbs. to use K9 Advantix II Medium 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 Medium Dog is a trademark of Elanco or its affiliates. Review: Very effective - Works great to get rid of fleas. It also keeps the fleas away when used monthly. There isn’t a strong odor. The product fully absorbs in about 2 days so others due is mildly greasy for a day. Good value . Review: After half a year of fleas, switching to this product completely got rid of them! - Cannot recommend enough! I live in the middle of the mountains next to a large national forest. There's deer, beer, turkey and all sorts of wildlife moving through my yard and in the woods year round, visibly agitated by fleas. My dog of 14 years finally got fleas (she's an inside dog with lots of outdoor playtime), as I've been thorough with checking her fur during brushings and baths. I usually just give her monthly flea baths which sufficed, but after a neighbor clear cut their property I've had an influx of wildlife on my property and I think that contributed to my dog getting fleas, I'm not sure. Regardless, she had fleas and they became an irritating presence within my home. Unfortunately, there's plenty of carpet for them to hide in and lay eggs. Yuck! I tried everything to get rid of them! Carpet powders, flea baths (different brands), furniture spray, cheap flea drops.. nothing worked. I battled with them for almost 6 months!! My poor dog was waking up constantly scratching and pacing back and forth throughout the house. I felt like an awful parent and was going crazy before finally deciding to look into the more expensive options.. Now, considering how much I spent on cheaper alternatives that didn't work or get rid of the problem at the source, I really wish I would've went straight for the higher priced option first. Within a matter of weeks of using this product I saw a quick decline in fleas inside the house and on my dog. Within one to two months, they were completely gone! I was in complete shock. I cannot praise this product enough. Maybe it's so effective on the fleas in my area since I live in the rural countryside where they're not used to it, as opposed to city fleas, so your mileage may vary. But for me this was a miracle product and I will be using this as a preventive measure in the summer months, with a periodic dose in the winter. If you struggled with fleas for months and months like I have, you will know the complete relief that comes with a flea-free home. Don't skimp! It may be more expensive than the alternatives but trust me with I say I tried all of them and nothing came close to getting rid of them, whereas this treatment was so fast and effective I was left nearly crying when I saw my sweet dog sleeping soundly through the night. :) ## Features - K9 Advantix II Medium Dog 30-day treatment & prevention protects dogs 11-20 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 | B00I2266Y2 | | Active Ingredients | Imidacloprid, Permethrin, Pyriproxyfen | | Age Range Description | 7 weeks and older | | Allergen Information | Allergen-Free | | Best Sellers Rank | #428 in Pet Supplies ( See Top 100 in Pet Supplies ) #7 in Dog Flea Drops | | Brand | K9 Advantix | | Brand Name | K9 Advantix | | Customer Reviews | 4.4 out of 5 stars 33,575 Reviews | | Dog Breed Size | Medium | | Global Trade Identification Number | 00724089060631 | | Item Form | Topical | | Item Type Name | Topical | | Item Volume | 2 Milliliters | | Item Weight | 0.32 Ounces | | Manufacturer | Elanco US Inc | | Manufacturer Part Number | 86314991 | | Model Number | 86314991 | | Pet Type | Dog | | Scent | Unscented | | Scent Name | Unscented | | Target Species | Dog | | UPC | 724089060631 | | Unit Count | 2 Count | | Volume | 2 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:** Medium - **Item Form:** Topical - **Item Volume:** 2 Milliliters - **Item Weight:** 0.32 Ounces - **Scent:** Unscented - **UPC:** 724089060631 ## Images ![II Medium Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs 11-20 lbs. | 2-Mo Supply - Image 1](https://m.media-amazon.com/images/I/71VIzeRO-YL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: does this work on mosquitos** A: Yes!
