It's been about a week and Dreyfus is like a new pup. Vicky taught us how to train him. He no longer jumps up on people, no longer counter surfs and doesn't chew on everything like a termite! He still has a few more things to learn but I see remarkable progress everyday!! Vicky is an angel. If you are having problems with your pup, please contact Bark Busters. You will shocked at the change in your dog; no more bad behavior and it is easy to do. No shock collars, no yelling or smacking. Just vocalizations. Your pup will be happy because you are happy!!
