The doorbell may signal an exciting or worrying visitor. Begin by managing the real doorway: give your dog a comfortable space away from the door while people arrive. If your dog is fearful, they need not greet visitors. Do not rehearse at full volume when your dog is already barking and distressed.
Start with a quiet version
Play a doorbell recording at a low volume that your dog notices without becoming worried, then offer a reward. If they react, lower the volume or create more distance. Separately, reward them for choosing a bed or mat. Once each piece is comfortable, try the quiet sound and cue the bed, rewarding the choice.
Where should I start?
Choose what fits. Nothing is saved or submitted.
Add real-life steps slowly
Practice with a helper, then a real knock, while your dog remains comfortable. Let household members know the plan and use a sign asking visitors not to ring during practice if that helps. A dog may still give an alert bark; the aim is a manageable routine, not forced silence. For a dog who growls, lunges, or has bite risk around visitors, maintain secure separation and seek qualified help.
