My SIL did. They taught her some techniques , but none worked on her dogs. One thing they told her was to use a chain and drop it on the floor ( so the loud noise would make them quiet) but I guess thay didn't take into account the heavy chain + hardwood floor = dents
They came back out twice for the barking , but they still bark like mad. She does have 5 so maybe it work one on one or just a couple. IDK.
