I understand the necessity of the transmitter and receivers being large to allow such a powerful and long distance signal, however the collar was very very large, it would hang at his chest and smack his chest as he ran. This collar kit would be good for larger dogs, or I would recommend getting a harness style vest with pockets that the collar can be put into instead of around the neck.
