Police say a dog alone in a pickup had to be rescued after it caused the truck to go into a lake in Maine. Police say a man was walking the dog near Branch Lake on Saturday afternoon in Ellsworth. He put the dog into the truck after an encounter with another dog. While the man spoke to the other dog's owner, the Yorkshire terrier managed to bump the Chevrolet Silverado into gear, causing it to roll about 75 feet into the lake, and bounce off a rock before sinking in roughly 10 feet of water. Police say a family friend immediately swam into the lake and saved the trapped dog; no humans or dogs were injured. (More dog stories.)
