Please, Please, Please, don't debark your poor baby how would you feel if someone decided to take out your voice box, vocal cords or whatever you want to call it if they felt you spoke too much and got on their nerves? I found this don't know if it really works and they say it's for the outdoors, they have postitive reviews on it and it's not that expensive, possibly less than debarking.Good luck to you and I hope with all my heart that you reconsider before going through with it.
