Narrated by Teddy, the story moves quickly and doesn't need too much more explanation of Teddy's ability to communicate other than the simple fact that he was brought up among words by someone who loved them dearly.
Teddy is grieving the loss of Sylvan, but connecting with the children eases his pain-- Nickel walks through the woods with his hand on Teddy's back in the way that Sylvan did, and Flora feeds and takes care of him. While basking in the children's presence, Teddy thinks back to the last days in Sylvan's life and remembers both the good and the bad things. As Teddy himself laments (although dogs cannot cry), it is a poignant time.
Adults will love this as a tissue-worthy read aloud to join the ranks of books such as DiCamillo's The Miraculous Journey of Edward Tulane , Patterson's Bridge to Terebithia, and Wiles' Each Little Bird that Sings.
