When Pony gives Dog a present, things quickly spiral out of control in this sweet and funny first book in a Level 1 Ready-to-Read Graphics series from award-winning author-illustrator, Jeff Mack!

Pony has a surprise for Dog—a pet rock! Dog would have preferred a T-Rex, or a moose, or a cow for a pet, but Pony says if Dog gives the pet rock a name, Dog will like it more. Dog names his pet rock Lulu the T-Rex and says it likes to eat ponies! Uh-oh. Will Dog and Pony and Lulu learn to get along?
