12 MONTH K9 ADVANTIX II Large Dog (for dogs 21-55 lbs)

All new K-9 Advantix II effectively treats and protects your dog from fleas and tick infestation. Dogs and puppies older than 7 weeks, weighing 21-55 lbs can be treated with this water resistant formula that protects your dog continuously, even after shampooing and rain exposure.

Eliminate fleas and other insects completely by attacking them at their source and preventing their growth into your dog’s surroundings. K-9 Advantix II offers complete five-way flea and insect protection.

Flea killing properties such as adulticidal, larvicidal, and ovicidal kill fleas and prevent new ones from emerging. K-9 uses an insect growth regulator called pyriproxyfen that disrupts hormone signaling of insects, preventing fleas from maturing. This integrated flea control (IFC) includes imidacloprid which kills fleas through contact and helps reduce flea allergy dermatitis.
