afraid it takes longer than the weekend to use a e collar but they do work you must and I mean must use a dummy collar for a week at least then use the collar after that its so the dog doesn't act up when the collar is off if ya do borrow a collar there should be a training DVD I would watch that 1st of all because shocking the dog willy nilly could make it have a hole other set of problems so its a must to do it correctly and it will do the job it did mine
