Dogs' nutritional needs change throughout life, from puppyhood through senior years.
Puppies need energy-dense food with appropriate calcium and phosphorus ratios for proper bone development. Large breed puppy formulas carefully control these minerals to support healthy growth without excess that could affect developing joints. Puppies typically eat puppy food until 12-18 months (longer for giant breeds).
Adult dogs need maintenance nutrition that sustains health without promoting weight gain. Activity level influences caloric needs—working dogs need more than sedentary companions. Food should be appropriate for size, as small and large breeds have different nutritional requirements.
Senior dogs may benefit from easily digestible food with joint support ingredients. Some need fewer calories due to reduced activity, while others require calorie-dense food if they tend toward weight loss. Dogs with age-related health issues may need therapeutic diets.
Pregnant and nursing dogs have significantly increased nutritional needs, often eating puppy food during this period for extra calories and nutrients.
When transitioning between life stages, do so gradually over 7-10 days to avoid digestive upset. Choose foods from manufacturers that conduct feeding trials and employ nutritionists.
