As you know I acquired a remote control collar as a last resort to try to stop my Burmese Mountain Dog from sniffing crotches! I had tried everything else – dog training classes; water pistols; audible warning devices; and, of course, making my displeasure known in no uncertain terms. Nothing had worked, and he was very much a ‘social outcast’. The collar had an immediate result. and it has had no, ill effect on him at all. Life is now much more enjoyable for him – and for us. I would recommend its use to anyone provided it is done sensibly and with affection.
