The Faithful Dog

The Fables of Phædrus
The man who becomes liberal all of a sudden, gratifies the foolish, but for the wary spreads his toils in vain.
A Thief one night threw a crust of bread to a Dog, to try whether he could be gained by the proffered victuals: “Hark you,” said the Dog, “do you think to stop my tongue so that I may not bark for my master’s property? You are greatly mistaken. For this sudden liberality bids me be on the watch, that you may not profit by my neglect.”
