One day, when hunting the wild boar, he seized the creature by the ear, but his teeth giving way, he was forced to let go his hold, and the boar escaped. Upon this the huntsman, coming up, severely rate him. But the feeble Dog replied: "Spare your old servant! it was the power not not the will that failed me. Remember rather what I was, than abuse me for what I am.
