The Akbash dog

One of the not so common dog breeds is the Akbash. Commonly seen guarding sheep herds this breed of working dog is a "guarding" of livestock. Very often the pups are raised with sheep so they learn to protect them. They are native to Turkey and the name Akbash means "whitehead." The dog is large 90 to 120 pound animal and is not shy. Their selective breeding has made them more inclined to think for themselves and less of a companion dog. Because of their prowlness, predators are inclined to want to get rid of whiteheads so they can feast on some lamb chops.

I bet you have seen those dogs guarding sheep herds, I have.
