A Greenfield man escaped injury and managed to chase off two coyotes when he spotted them attacking his German shepherd. The incident happened a couple of weeks ago. Scott Schach says he grabbed one of the attackers by its tail and leg and threw it as far away as he could. That coyote ran off. Schach’s 90-pound dog had the other intruder pinned to the ground, so he commanded her to sit — and it took off, too. Even though he was bitten, Schach says it didn’t break the skin, his dog is fine and things are back to normal. He is considering the installation of motion sensor lights to discourage a return visit.
