I completely agree with Aly. If you scold him when he comes back, he thinks he is getting scolded for coming to you. It feels weird and it's hard sometimes not to be upset or angry. Especially if there are cars or other dangers around. Duncan is usually very good about staying close by off leash or if he "escapes" out the front door. If he does start to wander, I've found that walking away, down the sidewalk or towards the car and saying "This way" works with him. He doesn't like me to be out of his sight or if he thinks I'm leaving, he always wants to go with me so walking the other direction usually works whereas standing at the front door calling him doesn't.
