1. **Desensitization**: Start by desensitizing your boxer to the sound of the doorbell. You can do this by playing recordings of doorbell sounds at a low volume and gradually increasing the volume over time.
2. **Counterconditioning**: Associate the sound of the doorbell with something positive, like treats or playtime. Every time the doorbell rings, reward your boxer with a treat to create a positive association.
3. **Training 'Quiet' command**: Teach your boxer a 'quiet' command. When your boxer barks at the doorbell, use the command and reward them when they stop barking.
4. **Distraction**: Redirect your boxer's attention when the doorbell rings by giving them a toy or asking them to perform a trick.
5. **Consistency**: Be consistent in your training efforts and practice regularly to reinforce good behavior.
Remember, patience is key when training your boxer. With time and effort, you can teach your dog to stop barking at the doorbell.
