Ending1: Make sure your dog knows that you have food in your hand. Let them smell the food in your hand. Ending2: When they sniff the treat, they will start following it, too. When they look up into your eyes, they will know that they are approaching something. Ending3: This should be all that your dog comes to associate as " follow " and not a treat. This will prevent your dog from snapping at you. Ending4: [substeps] When you notice that your dog is following you, greet him by giving him a treat. If he follows you, reward him with a treat as soon as he obeys the command.
