★ "Sullivan again displays her gift for concise animal comedy."--The Bulletin of the Center for Children's Books, STARRED review

Geisel Honor winner Mary Sullivan humorously and deftly delivers a sweet spin on cat-and-dog rivalry. Perfect for fans of Kelly DiPucchio and Vera Brosgol.

Bob the dog doesn't mind hard work when it means he can reward himself with a nap. But Someone is watching him sleep! Hopefully they will just go away if Bob lies really still. But Someone, who happens to be a cat, has other things in mind.

Up on Bob is a humorous tale about sharing, working hard--and sleeping even harder. With irresistibly sly illustrations and pitch perfect pet dynamics, Geisel Honor-winning author-illustrator Mary Sullivan tells a sweet tale of friendship with a fresh new spin on the age-old cat-and-dog rivalry.
