Growth Rates of Animals

Hello. Thank you for taking the time to ponder my question.
I would like to know (in layman's terms) why animals life cycle is so much
quicker than humans. For instance, I just purchased a Boston Terrier
puppy. She was smaller than my shoe when I got her. Now, only twenty weeks
later, she is almost full grown. Why do animals grow at such a higher
rate than humans?
Growth rates are related to size and life span of the animal. For instance,
an elephant is large, grows slowly, and lives a long time, while a mouse is
small, grows fast, and does not live long. There is not a strict, fixed
relationship but this is in general true.
