9.1. Understanding Nutritional Needs

Different life stages, sizes, and activity levels require varying nutritional profiles. Puppies need more protein and fat for growth, while seniors benefit from joint support and fewer calories. Active dogs require more energy, while less active dogs may need fewer calories to avoid weight gain.

Life Stage: Puppies, adults, and seniors have different nutritional requirements.
Breed Size: Small breeds need more calories per pound than large breeds.
Activity Level: Active dogs need more energy than sedentary dogs.

Named Meat Sources: Ensure you know the exact protein source.
Avoid Artificial Additives: Can cause allergies and other health issues.

9.3. Potential Allergens and Sensitivities
