Dogs, like humans, have specific nutritional requirements that change throughout their lives. Understanding these needs is crucial for maintaining your dog's health and longevity.

Puppies require diets rich in protein and fat to support their rapid growth and development. Look for puppy formulas with at least 22% protein and 8% fat. These should be fed in multiple small meals throughout the day.

Adult dogs (1-7 years) need balanced nutrition to maintain their weight and energy levels. The exact requirements depend on size and activity level. Active breeds may need 25-30% more calories than sedentary dogs.

Senior dogs often benefit from diets with fewer calories but higher fiber content to prevent obesity and maintain digestive health. Many senior formulas also include joint-supporting supplements like glucosamine.

Special considerations include:

• Large breeds: Need controlled calcium and phosphorus levels to prevent bone disorders
• Working dogs: Require high-fat diets for sustained energy
• Dogs with health issues: May need therapeutic diets prescribed by veterinarians

Always ensure fresh water is available, and consult your vet before making significant dietary changes.
