Dogs typically eat a diet that consists of dog food specifically formulated for their nutritional needs. This can include dry kibble, wet food, or a combination of both. It is important to provide dogs with a balanced diet that includes proteins, carbohydrates, fats, vitamins, and minerals to keep them healthy. Additionally, some human foods are safe for dogs to eat in moderation, such as cooked lean meats, fruits, and vegetables. It is best to consult with a veterinarian to determine the most suitable diet for your dog based on their age, size, and health conditions.
