The fable of Fedro

The skinny wolf found a rich house dog, fat, round, well-groomed. He took care of the employer's house. This assured him food in abundance, safe shelter and well-being.

The wolf thought that caring for fences in exchange for such satisfaction was too tempting. They were walking and the wolf saw a strange signal on the dog's neck. "What's that?". The happy dog explains that it is nothing, just the mark of a chain. "How?" The wolf is amazed. "Do you mean that the price of what you enjoy is the chain?" "Yes, but for a few hours. At night they let me loose so I can watch. "

The wolf went back to the mountain, with all the snares and famines.
