A dog's diet is essential for its overall health and well-being. It typically consists of a balanced mix of proteins, carbohydrates, fats, vitamins, and minerals. Many dog owners choose commercial dog food, which comes in dry, wet, or raw forms, ensuring that it meets the nutritional standards set by organizations like the Association of American Feed Control Officials (AAFCO). Some pet owners opt for homemade diets, which can include cooked meats, vegetables, and grains. It's important to avoid certain foods that are toxic to dogs, such as chocolate, grapes, and onions. Consulting a veterinarian can help ensure that a dog's diet is appropriate for its age, size, and health needs.
