Dogs are typically fed commercial dog food formulated to meet their nutritional needs. Dog food comes in various forms, including dry kibble, wet food, and semi-moist food. The specific type and amount of food depend on factors such as age, size, breed, activity level, and any specific dietary requirements or health conditions. It's important to choose high-quality dog food appropriate for your dog's life stage, provide fresh water at all times, and avoid feeding them harmful foods like chocolate, onions, grapes, or foods with high salt content. Regular feeding schedules, portion control, and monitoring your dog's body condition help maintain a healthy weight and overall well-being.
