Product 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.

Application key benefits
Easy-to-apply topical solution – no hard-to-swallow pills
Easy Application – Step 1
Holding the tube upright and pointed away from you and your pet, remove the cap from the applicator tube. Turn the cap around, place it back on the tube and twist to break the seal.
Easy Application – Step 2
Evenly apply the entire contents of the tube along the top of the dog’s back, from the shoulder down to the base of the tail. The number of spots depends on the size and weight of the dog (please refer to the product label). At each spot, part the hair until the skin is visible. Place the tip of the tube on the skin and gently squeeze a portion of the solution on the skin.

5.0 out of 5 stars It works!! I have been using Advantix for my Toy Poodle for 11 years. His name is Ty and maintains 12 lbs. He came home with a tick last week and the tick jumped right off him and onto the floor. Same 2 other times. They seem to hate the Advantix and get off.I trust the product. Just remember to avoid bathing 2 days before or after. If not, it will affect its efficacy.Variation: Size: 4 Pack

5.0 out of 5 stars The Day the Fleas Packed Their Bags 5 stars. The fleas showed up. They rented tiny imaginary apartments in my dog’s fur. Just a quick drop in a few spots. Now the fleas are packing their bags and moving out. Zero stars from the fleas. Five stars from us.Variation: Size: 2 Pack

5.0 out of 5 stars Works on fleas This worked on fleas. Frontline didn’t work, advantix didn’t work. Advantix II was the only thing that killed the fleas.Variation: Size: 2 Pack

5.0 out of 5 stars K9 Advantic II is THE BEST I started using these in 2009 when my first dog got infested with fleas from the carpet in our new home. We tried other things, collars, baths, drops, but my cousin recommended the K9 Advantix II. SEVENTEEN years and the more dogs later, and none of my dogs have ever had another problem with fleas or ticks again.Variation: Size: 6 Pack
