What is the author's tone in the book, Giant George: Life with the World's Biggest Dog?

The tone of the story is one of humor. Dave looks back on his story and tells it so that he identifies the humor in the situations in which he finds himself. There is humor in the way that Dave describes George's habit of running for the door whenever he hears the doorbell. This same humor is used when Dave describes the way that he and Pete, the airport manager, try to find a place on the plane where George will fit comfortably. Dave also looks back with humor on the moments before the Oprah show appearance when he "lost" George, even though he probably wasn't feeling the situation was very humorous at the time it was happening.

While humor is the main tone of the story, there is also tension in the story. Some of the more tense moments come when Dave learns that George's measurements have been challenged and that they must be verified. Dave and Paul are worried about what sort of person might be sent as the adjudicator from Guinness to complete the verification of George's measurements. Dave also worries that George will act up during the session and they won't be able to get a good measurement on him. A bit of the tension is relieved when Paul notices the framed certificate in Jamie's briefcase, but neither can fully relax until George's height is verified at forty-three inches.

As in any other story, Dave's story also has sadness. This sadness comes especially sharply when Christie loses her first baby during her twentieth week of pregnancy. The loss of the baby is included because it helps illustrate just how integral a part of the family George really was. He is able to comfort Christie in a way that Dave can't. When Christie has to go to the doctor out of town to have labor induced, she wants George to go with them.
