So what is a GSH? I lost apointerfor about three weeks years ago, pre chip. Had a Dunn's locate tag on her and the guy that found her called them three time's and they didn't know what he was talking about. Wife worked about 25 mi from him and he just happened to stop in the store and was telling her about the pointer he'd found, it was my Katie! My name and phone number is on all dog tags now.
