Do not rely on your puppy's eagerness for food as a sign they need more. Many puppies will beg even when they are full. Overfeeding increases the risk of rapid weight gain, joint strain, and health problems later in life. On the other hand, underfeeding can limit energy and slow development. Review your puppy's portions regularly and adjust as they grow. Balance is not just about quantity, but about timing, quality, and how your puppy responds to their diet.
