Dog food is specially formulated nutrition designed to meet a dog’s dietary needs. It comes in various types, including dry kibble, wet food, raw food, and semi-moist options. Common ingredients include proteins (chicken, beef, fish), carbohydrates (rice, sweet potatoes), fats (fish oil, flaxseed), and essential vitamins and minerals for overall health. There are specialized formulas for puppies, adults, seniors, and dogs with specific health concerns like allergies or joint issues. High-quality dog food avoids artificial additives and is often labeled with AAFCO certification to ensure it meets nutritional standards. Proper portion control is essential for maintaining a dog's health.
