We bought a boxer puppy for our children. Boy she was terrible, chewing things up, refused the leash and we began to thing we would never get her potty trained. Her manners were nearing being unbearable and we were considering finding her a new home. After a couple of months in puppy training at Good Shepherds she is a changed dog. She minds, no long has accidents in the house and has become a joy to have around. They are very skilled at Good Shepherds. Give them a try!
