FILE - In this Dec. 8, 2011 file photo, Harriman, Tenn., resident Shannon Robinson shows the map displayed on his GPS device that tracks the location of his hunting dogs. Animal rights groups are suing California over rules that allow animals to be hunted with the aid of hunting dogs wearing GPS tracking devices on their collars. The Animal Legal Defense Fund says the hunting method is "cruel and unfair." The group says tracking devices allow dogs to chase prey to the point of exhaustion. Then hunters follow the GPS to find an animal that is easily shot. The lawsuit targets the Fish and Game Commission, which didn't immediately respond to requests for comment.
