Dexter is a very good goat, except when it’s time for hoof trimming at the zoo, and he must learn to be brave even when he’s scared. Dexter is the top goat at the petting zoo, but he's not the bravest, much to his embarrassment. He has the longest, smoothest, and straightest horns of all eleven goats, and he's very good at using them to keep the others in line. He's also a very good boy. Dexter never grabs the paper maps out of visitors' hands or sneaks into the alpaca pen for an afternoon grain snack. But he's secretly afraid of some things, like the generator, the big green ball, and--horror of horrors--having his hooves trimmed. Follow the zoo-yard adventures of this irascible goat and find what goes on inside his head as he learns to overcome his fears.
