Tiny and the Big Dig - by Sherri Duskey Rinker (School And Library)

Sniff! Sniff-sniff!
I smell a bone. A bone that's BIG.
I'll get it out, I'll dig and dig.
A big, BIG bone! I know it's there!
It will take work, but I don't care!
Tiny may be a small dog, but don't let that fool you. He's a pooch with power who knows what he wants. And he's going for it. But oh, those pesky pessimists -- they're trying to rain on Tiny's dig-parade!
Thank goodness for one special boy who believes in Tiny, because in the end, this dog's grit proves that he's the little pup who could... dig up some giant surprises!
