I just wanted to share with you how well Guido (the big rott from FL and WI) is doing. He really listens and has finally learned the back leash (after several corrections, he is still stubborn after all). He has been wonderful with all house guests. He has been great around my granddaughter. My daughter got married last weekend and we had a house full of strangers. He seemed to enjoy all the chaos and just sat calm as can be in the middle of all the preparations and strangers running about. I was very proud of the dog you helped us to mold. Thanks so much for ending my stress and frustration, and giving Guido a life we can all enjoy. Also, my newly married daughter is planning on adopting a shelter dog in the coming weeks and I plan on sharing all my Bark Busters knowledge with her.
