Vets All Natural Complete Mix for Puppies by Dr Bruce represents the vegetable matter and grain portion required in your puppy's diet. If your puppy is less than one year old, they will thrive on this formula. Puppies need more protein, base nutrients and vitamins than adult dogs to sustain their rapid growth rate, and in order to achieve this the VAN Puppy formula includes more yeast, calcium, kelp, barley grass, lecithin and vitamin C than the adult product. Vets All Natural Complete Mix is formulated in accordance with the principles of raw food to avoid the harsh damage to proteins, vitamins and enzymes that are caused by cooking; instead all ingredients are air-dried at (or below) body temperature. It is an economical way to ensure your dog gets the best; simply add VAN Complete Mix to the appropriate portion of raw meat - such as kangaroo, rabbit, beef, mutton, lamb or organic chicken, and you have a 100% preservative and additive free, completely natural, raw, perfectly balanced meal.
