I am a Mini Dachshund Breeder, and I have been using Nu-Vet Plus since 2011. I have 44 dogs right now, and all my Dogs are on Nu-Vet except the little ones that haven't opened their eyes yet. I start them on it as soon as they start eating their food. I love it and they do too. I always give it to my Dogs before they get anything else, my grown Dogs, and they think it is a treat. I see it in their Hair Coats, and the way they Run and Play. I love my Dachshunds, and my Dachshunds love Nu-Vet Plus!
