Goodnight, Good Dog is nice.  Period.  It is the explanation of a dog who doesn’t want to sleep even though everyone in the rest of the house is.  Finally he settles down and sleeps, dreaming of the things he liked during the past day.  The prose is simple yet slightly monotone. The best page is when the dog recognizes the lullaby rhythm of the title’s repetition as he curls up in him bed.  The illustrations are basically primary and secondary colors.  Such simplicity could only be for the benefit of the youngest of listeners, but this reader wonders if even that will hold their attention.  Not recommended for school libraries.
