Feeding a German Shepherd puppy homemade food requires a balanced diet rich in protein, fats, and essential nutrients. A good meal might include cooked lean meats like chicken, beef, or turkey mixed with brown rice or sweet potatoes for carbohydrates. Add vegetables such as carrots, peas, and spinach for vitamins and minerals. Include a small amount of fish oil for healthy fats and omega-3 fatty acids. Ensure portions are appropriate for the puppy’s age and size, and always consult with a vet to ensure the diet meets all nutritional needs for healthy growth and development.
