The term for a young dog is "puppy." Puppies are typically considered to be dogs that are less than one year old. During this developmental stage, they undergo significant growth and learning, acquiring essential socialization skills and training. Puppies are known for their playful nature and curiosity, which can often lead to mischievous behaviors. Proper care and training during this critical period are essential for shaping a puppy's behavior and personality, ensuring they develop into well-adjusted adult dogs. The bond formed with puppies during this time can create lasting companionship.
