Even if not reintroduced, it won’t be long before the wolves in Wyoming start making their way down anyway.
They already have. It’s not been publicly acknowledged because there are powerful land-use interests that want us to believe that they are only shooting “coyotes.”
That said, the cheapest and most effective way to protect herds is with dogs. They’ve been doing it in Europe and parts of Asia for thousands of years, so it’s not as if the knowledge isn’t out there. It’s what your giant breeds like mastiffs, great Pyrenees and Anatolian shepherds and the like we’re originally bred for.
