The Sheep-pig : 40th Anniversary Edition by Dick King-Smith

When Babe, the little orphaned piglet, is won at a fair by Farmer Hogget, he
is adopted by Fly, the kind-hearted sheep-dog. Babe is determined to learn
everything he can from Fly. He knows he can't be a sheep-dog. But maybe, just
maybe, he might be a sheep-pig.
