When I was at the GSD Adoption Event, those handling the Shepherds who were acting up against the other dogs, would say, "Walk it off!" The emphasis was on walk. It seemed to take their minds off the other dogs and concentrate on walk. They would then move them around. Sometimes Shiloh will bark at other dogs when we are on our walks and I tried this method. It really worked. She would stop barking and start walking. This would be for mild cases only, however.
