National Geographic produced a wonderful 2-hour TV show called And Man Created Dog. In this selection we learn about a group of Pyrenees dogs who herd goats. The dogs are raised from birth with the goats so the goats become their family. In the morning they lead the herd out into the hills, going ahead to be sure all is safe. In the evening they bring them all back.
The farmer says “When we bring the goats in, we count the dogs, not the goats. Because if we have all of our dogs, we know we have all of our goats.” It’s an amazing story. You’ll love it.
