Dog Gets a Pet - Jeff Mack - Bog

"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?"--]cProvided by publisher.
