Moondogs is a really cute story.
Willy Joe Jehosephat's parents are worried about their little boy who's quite the loner, so they decide Willy needs a pal, a pet. When Willy's dad announces they'll be going to buy a dog, Willy lets him know that the very best dogs are found on the moon, and sets about building a rocket ship to take him there.
This is a fun, imaginative story, filled with lots of colorful illustrations. My grandson was more interested in the pictures than the story itself, but I'd expect that from an almost 3 year old.
