They do where I grew up, and the Basques raise sheep there. It's just that the sheep was slaughtered by the shepherd and the meat is called mutton.
See Kipling's short story "The Knife and the Naked Chalk."
Basques? That would be the part of the world where a group known as the Basque Seperatists reside?
As a proud member of the clan of Sheepdogs I need to point out a few things to you:
#1 The essay is SYMBOLIC not literal. Real wolves eat sheep...and cattle and when the opportunity presents itself (rarely)....people. Real sheep eat grass and other green stuff (sound a lot like the PETA freaks and other liberals). Real people who aren't vegans or liberals...eat sheep, beef (it's what's for dinner!) and fish. Not to mention various kinds of bird species.
#2 This is obviously not where you grew up. But this essay was written by an American...about American's. While I'm sure there are other cultures that have their own sheepdogs, I'm equally certain there are none so plentiful as the sheepdogs (People Sheepdogs) we breed in this country if only because of our connection to the 2nd Amendment of the US Constitution. The U.S. Constitution is unique in all the world as it was originally designed to restrain the government from acting unilaterally against it's own citizenry. Therefore American Sheepdogs must also be held to be unique.
