In 1994, Ian Dunbar, a veterinarian founded the Association of Pet Dog Trainers, or APDT (wow, that is not too long ago). Dunbar advocated positive reinforcement, such as using treats for training dogs. I believe in this also. I might add, use a soft treat such as a cut up hot dog when using treats while walking. If you do use a solid hard treat, make sure you give the dog time to eat and enjoy it. Don’t forget to take water, but don’t use the water as a treat.
