K9 Advantix II

K9 Advantix II is manufactured by Bayer, a leading name in the healthcare industry for over 150 years. Finding its roots in making aspirin for people, Bayer ultimately committed itself to keeping pets happy and healthy as well. With the belief that cats and dogs deserve the same treatment as their human counterparts, Bayer has created a legacy of innovation and quality that guides them in every step. K9 Advantix II is a monthly topical application for dogs and puppies that provides a broad spectrum of protection. Working to repel and kill fleas, ticks, and mosquitos, it also kills all life stages of fleas to prevent the cycle of infestation. It uses a combination of three powerful ingredients that are perfectly safe for dogs and humans, and they work together to kill the parasites that could transmit disease-causing organisms. Advantix II starts working within 12 hours of application, and it’s waterproof so dogs can still be bathed or take swims without worry.
