VetGuard® Plus for Dogs provides two active ingredients that work together to keep pesky invaders off and away from your dog. Permethrin ? a powerful, fast-acting insecticide that kills and repels adult fleas, lice, ticks, and other invaders for up to four weeks with just one application. And, Pyriproxyfen (Nylar) ? an insect growth regulator that targets and destroys flea larvae, keeping future generations off your dog. VetGuard® Plus for Dogs is an affordable solution that protects your pet. VetGuard® Plus for Dogs is made in America and can be used for dogs over 12 weeks of age. As with all flea and tick solutions, VetGuard® Plus for Dogs should be used as part of a program aimed at reducing flea populations in the pet?s environment (bedding, carpets, kennel, and yards).
