Explanation

Amy Saito wrote the narrative  poem named Night walk which is a narrative description of the life and experience of a little puppy. The poem is very specific about the aspirations and the goals of this puppy who wants to walk all night in the darkness, however, the master doesn't permit her to do so since she is very small and delicate.The sky above, the streets below, The stars reflecting off the snow— A lovely night for us to go out for a walk, the puppy thinks; These lines exemplify that the background under which the little puppy and the master is going for a walk is perfectly suitable and favorable."Can’t run all night when she’s so small. Someday she’ll grow a little more And when she’s three, or maybe four She’ll run all night, and she’ll be tough— Tonight, though, she’s gone far enough"These lines are, however, refuting his earlier observation that the night is good for a  walk. Here the master opines that the puppy was too small and delicate to go for a walk. At the same time, he is very optimistic that someday down the line he is going to become stronger and capable to go for a  walk in the darkness of night. The theme here is that every small and little thing through the passage  time becomes strong and wonderful.
