Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE SHEPHERD, THE WOLF CUB AND THE WOLF
A shepherd found a new-born wolf cub. Taking it home, he raised it with his
dogs. After the cub had grown up, he would join the dogs in the chase if a prowling
wolf ever stole one of the sheep. When the dogs were no longer able to keep
up with the other wolf and turned back for home (as sometimes happened), the
wolf would continue the chase until he caught the other wolf and received an
equal share of the prey, true to his wolf's nature. Then he too would go back
home. If, however, no wolves came to seize the sheep, he would secretly slaughter
one of the sheep and eat it together with the dogs. When the shepherd finally
guessed what was happening, he hanged the wolf from a tree and killed him.
The fable shows that a wicked nature does not produce a good character.
