Aesop's Fables (1884)
206. The Man Bitten by a Dog.
A Man who had been bitten by a Dog was going about asking who could cure him. One that met him said: "Sir, if you would be cured, take a bit of bread and dip it in the blood of the wound, and give it to the dog that bit you." The Man smiled, and said: "If I were to follow your advice, I should be bitten by all the dogs in the city."
He who proclaims himself ready to buy up his enemies will never want a supply of them.
