How can I prevent a dog from running away?

A good exercise to do with dogs that like to run away is to teach the ‘come’ command. Attach a long leash (10 meters is fine). That way, he may get the impression that he is off-leash and if he tries to bolt, you can stop him by holding or stepping on the leash. Use food to give him an added incentive to come to you on command. Better yet, make the ‘come’ command the only time during the day he gets fed. If this doesn’t work, you’ll have to use an electric collar which will give you complete off-leash control of your dog.
