Step 1 Find lures to distract your dog such as food, toy and etc. Step 2 Distract your dog with the lure, quietly and quickly leave the house. Do not say anything to your dog *Saying good bye will lead into anxiety.
Step 3 * If your dog starts to whine and bark, wait until it stops. In some cases it will take more time than expected, be PATIENT.
Step 4 Return back to the house < 1 minute after it stopped barking. Repeat this process and increase the duration bit by bit. This teaches your dog to get used without your presence.
