Which needs caring for the longest calf puppy or human body?

A human body typically requires care for a much longer duration than a calf or puppy. Human infants are dependent on caregivers for several years, often needing support into their teenage years as they mature. In contrast, calves and puppies generally require intensive care only for a few months before they can start to become more independent. Overall, the long-term care and nurturing required for humans significantly surpass that of calves and puppies.
