I didn't learn about NuVet until my last two pups were seniors, but as soon as I read about NuVet I checked with my vet and ordered both the NuVet vitamin and the NuJoint supplement. What a difference I saw in my old friends. Better movement and more energy, it was like they had aged in reverse a couple of years. I have since told almost everyone I know about the NuVet products and all that have tried it have thanked me as they have seen a difference in their pups also. My current dog was on NuVet as soon as I got him, and the puppy I am waiting for will be also. This product is amazing, I truly saw a difference in my pups and my friends also. I hope everyone who tries this has as much success as I have.
