Growing puppies have specific nutritional requirements that differ from adult dogs, particularly with respect to their calcium and phosphorus balance, and an overall increased calorie demand. Vitamin and mineral deficiencies for a growing puppy can result in a variety of problems, so as a result, a puppy should not eat adult dog food on a regular basis. An occasional bite from their older housemate’s bowl should not pose any problems, but stick with puppy food as their dietary staple.
