Whatever Works

This is a (mediocre) photograph of dogs herding sheep (without the assistance of a human being) on the Navajo reservation in Arizona.

While on the Native American Cultural Tour, I learned that the Navajo also use llamas to herd sheep. The llamas use their sharp hooves to protect their charges.
There is no word for 'llama' in the Navajo language so they call them, goats uncles.
