Our Vaisto products labeled with PUPPY FORMULA are meant for puppies that are still growing in height. The products contain a higher percentage of bones so that a puppy gets all the nutrients it needs to build a strong skeleton. There are also a few more vegetables in the products so the stool will not be too hard, and so that the dog is kept slender as it grows in height. The rest of the nutrients (meat, organs and oil) give your puppy the proteins, vitamins, fatty acids and other essential nutrients that it needs. PUPPY FORMULA products should be used for the whole time that the puppy is growing in height. When the dog has grown to its full height, it is time to move to the other Vaisto products.
