Many of my breeder friends were using NuVet Vitamins and raving about it. They were getting great results so I thought I would try NuVet too. I bought some and started a few dogs on it. I have to say I was very impressed. Their coats were shiny, softer, they blew their coats less after whelping and it helped with tear staining in my white dogs. If you double up 2 weeks before your spay or neuter your dog and 2 weeks after NuVet will help your dog heal faster! With my dogs on NuVet I know they are as healthy as they can be! I think NuVet is especially important to use the 1st 2 years of their life while they are growing.
