Whose Pet Is Best?, Volume 17

WHAT'S ON TV? IS IT NANCY DREW?
It's the Amazing Pet Contest, and the winner gets to go on Mr. Lizard's Funhouse . . . on TV! Katie's got a singing parrot. David's got a gross rat. And Nancy's got Chocolate Chip, her soccer-playing puppy. . . .
But Chip won't do her trick. Something's wrong, and Nancy's afraid she's sick. She also thinks it just wouldn't be fair if Chip doesn't get to go on TV because somebody played a dirty trick on her!
