Woolbur by Leslie Helakoski, illustrated by Lee Harper

From chapters.ca:
Woolbur is not like other sheep. He hangs out with wild dogs, cards his own wool to avoid the shearing barn, and even dyes his wool blue. "Don't worry!" says Grandpaa when Maa and Paa fret that Woolbur is different. But when they tell their son to follow the flock, the opposite happens — the flock follows him! Soon everyone is copying his wild hairstyles and taking turns on the spinning wheel. Leave it to Woolbur to find a new way to step ahead of the herd. Spunky, funky, and refreshingly distinct, Woolbur will strike a chord with anyone who's ever felt different. And that's all of us!
