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.
