Pigs Might Fly by Dick King-Smith

Poor Daggie Dogfoot! He’s much smaller than his brothers and sisters, with feet more like a dog’s than a pig’s. The very day that Daggie is born, the pigman whisks him off to the shed for a merciful death. When Daggie miraculously escapes, he returns to the safety of the sties and the protection of his mother, who begins to think that Daggie isn’t just different but special.
