A boy gets a puppy who becomes his best friend and companion. They grow up together sharing everything. As the boy gets older, he finds less time for his beloved pet, as girls, relationships and life distract him from his best friend. As the young boy grows up and matures, his dog waits patiently for him to return in order to continue their special and intimate friendship. Eventually, he marries and settles down to resume the extraordinary relationship with his dog -- until one day his best friend crosses the rainbow bridge, leaving him behind to struggle with the pain that only comes from the loss of a dear pet. This is a heartwarming story of the love only a boy and his dog share as told through a fully illustrated poem.
