Hi - I'm new to this forum....I was also looking for information on Vectra 3D. We've been using K9 Advantix for the last year on our 2 Maltese puppies Winston and Wesley (1 1/2 years). When I went to the vet today to pick up some more K9 they said that they no longer carry it and instead carry/recommend Vectra 3D. They've switched to Vectra because they said that dogs will develop a resistance to a product if they are on it too long so they recommend rotating...this logic made complete sense to me so we bought it. A six pack cost $95 and change. Our vet said that it will begin working within 6 hours of application and you can bathe your dog about 24-48hours following application. K9 worked really well for us in the past so I'm hoping Vectra will work jus[F][/FONT]t as well.
