I was given a sample of NuVet Plus when I bought my Chinese crested, Ringo. I wanted to keep him on them as recommended by the breeder. After reading about them on line and the wonder ratings it has I decided to put my older creasted on them. He had a lot of sores that would come up and he'd scratch un controllably. He had a lot of blackheads and my one main concern was his tough skin. He felt like petting an elephant it was so thick and tough. He would crinkle his skin when petted like it irritated him when petted. I figured it wouldn't hurt. To my surprise after just 2 weeks on NuVet I could see a world of difference in him. the blackheads were half as many and his skin was softening up, no more scratching sores on himself. He has been on NuVet since Feb. and he has the softest baby skin anyone could ask for. His blackheads are gone and hasn't has a sore since end of March. I for one am a firm believer in this wonderful product and will never be without it again. Thank you NuVet!!
