There once was a sheep farmer with a very large flock. So large he had to use lots of sheepdogs. His sheepdogs were trained to guard his sheep, guide them in for branding and shearing, and protect them and their offspring from predators – especially wolves. The sheep had come to love and trust the farmer, and because of that they accepted the role of the sheepdogs and came to love and trust them also.
Yet, as hard as the farmer and his dogs tried to protect them, every month there was always one or two lambs found with their throats torn out, their mothers bleating noisily at their side, trying to lick away the blood and make their babies whole again.
One spring the farmer had a visitor who wanted to evaluate his farming methods. The visitor’s name was Tom. Tom spent days and nights watching, taking notes, compiling his report. When he was done Tom presented his report to the farmer. Tom had concluded that the lambs were not being killed by wolves at all, they were secretly being killed by sheepdogs. Well, the farmer got angry when he read this and just tore up the report. “That’s nonsense!” said the farmer, “I know my dogs; I trained them well. They wouldn’t hurt a lamb. Never!”
In his report Tom also revealed that the farmer had not only known these facts to be true but also had previously sold to other sheep farmers any sheepdog he found with evidence of bloodshed on his muzzle. And furthermore he had done so without revealing to the new farmer the danger the sheepdog posed.
The farmer sent a letter to Tom’s boss and Tom was fired.
Besides revealing the covert behavior of the sheepdogs, Tom also reported that after each lamb was found slaughtered by the “wolves” the carcass was cut up and the bones were fed to the sheepdogs, whose blood lust was thereby further aroused.
