Does your dog come when called? Or do you just follow the trail of foot prints?

Look for Golden Opportunities to Teach Your Dog

Another golden opportunity to teach your dog is when playing ball with him. By using a dog whistle and voice commands, you can teach him to come back to you. When he does, he gets another ball thrown for him. Of course, keeping a long lunge line attached to his collar will ensure that your dog won’t run off.

The message to the dog owner is:
When your dog makes a mistake, correct him, and motivate him to learn through play.
