Why supplement if you feed a “good food?” NuVet nourishes your pet for the longest, healthiest life possible. Your puppy gets NuVet daily so we recommend that you continue this important supplement. Its main goal is boosting immunity, which is extremely important for puppies who are under stress (like going to a new home for the first time!) It also fills in vital nutrients missing in dog food to also reduce cell damage which causes rapid aging and supports overall long term health. NuVet plus also helps your puppy have less allergic reactions to vaccines by boosting the immune system.
