As a new dog owner, you should realize that the popular belief that puppies are in their healthy years in no way excuses neglect to their eating habits. A proper diet and the right dog food are what shape the habits and health of the dog your puppy will grow to become. On a fundamental level, your puppy needs nutrition, exercise, and love. But since, every dog has specific health needs, a nutritional approach must be tailored to your puppy's size, breed, and level of activity. Because of energy and development needs, puppies require food that offers more energy than adult dog food. It's important to remember that a dog's needs change as it gets older. The different life stages call for varying levels of fitness, care, and nutrition.
