K9 Advantix II

K9 Advantix II is Manufactured by Elanco, a global leader in animal health dedicated to innovating and delivering products and services to prevent and treat disease in farm animals and pets, creating value for farmers, pet owners, veterinarians, stakeholders and society as a whole.
K9 Advantix II kills and repels fleas, ticks and mosquitoes through contact, meaning they don’t have to bite your dog to die. K9 Advantix II is also vet recommended, so you can repel the bugs and propel the day. K9 Advantix II prevents reinfestations by killing adult fleas so they can’t lay eggs. Repels and kills mosquitoes for up to four weeks. Infected mosquitoes can transmit dangerous heartworms, making it important to protect against biting, blood hungry mosquitoes.* Fleas and ticks are killed on contact with a treated dog, which means that fleas don't have to bite and ticks don't have to attach to die. This helps prevent transmission of flea-borne and tick-borne diseases such as tapeworms, Lyme disease, tick paralysis, ehrlichia, and Rocky Mountain spotted fever. Killing fleas before they bite may also help prevent skin allergies caused by flea saliva.
*K9 Advantix® II is not a substitute for prescribed heartworm preventive. Do Not Use on Cats.
