Sometimes a dog isn't just a dog; sometimes he's the glue that holds a whole family together.
Mr. Mosely is a special dog. Not just because he's so big (he's part Great Dane). Not just because he's all white (with one black spot under his eye and a heart shaped splotch on his chest). Not just because he's clumsy, or because of tricks (he only knows one, and it's not very good). He's special because he seems to know exactly what everyone in Corey's family needs, even when they don't know themselves.
This is the story of Mr. Mosely, from his puppyhood to the last time he curls up on the back porch. It's the story of how sometimes a dog isn't "just a dog." Sometimes he's the glue that holds a whole family together.
