Meet Rocky, a tiny pup with a ton of personality whose spunk will have little yippers cheering. When poor Rocky has to move to a new house, five snooty cats make his life miserable. But Rocky has one thing the cats don't: a stouthearted "Arf!" that can stop naughty, teasing kids in their tracks. Rocky soon wins some grateful feline friends-and a permanent place as an honorary cat. With the witty, larky illustrations of Tamara Petrosino, co-authors Donna Jo Napoli and her sister, Marie Kane, have created a lovable new mutt hero whose heart is as big as his bark.
