Bailey is a likable dog, the only non-human student in Mrs. Smith's elementary school class. In this book, the class takes a field trip to a natural history museum. Bailey is very excited about the field trip, but early on he becomes a bit too interested in the dinosaur bones, starts to chew on them, and is assigned a new "buddy", a museum security guard. From there on, Bailey is very well-behaved, and the guard likes him very much. When Bailey takes a quick nap in a teepee, he and the guard become separated from the rest of the group. Bailey finds the way back to the group by following the scent of Tommy's socks, Sophie's bubble gum, and Mrs. Smith's perfume.
The text is simple and straightforward, but much more is added to the story through thought and speech bubbles, incorporating the points of view of Bailey, the other children, the teacher, the guard, the museum tour guide, and the other people in the museum. The illustrations are very good, in the style of a cartoon or graphic novel, and full of detail. Bailey mostly walks upright on his hind legs, but sometimes walks on all fours and never actually speaks. His thought bubbles are wonderful: he wonders if the clown fish miss the circus, if a dream catcher also catches squirrels, etc.
There is so much detail in the illustrations, and so many thought and speech bubbles, that a child could happily return to this book over and over again. Recommended!
