Teaching Your Dog To Be Quiet
Your dog needs to understand what the word means before you can use it.
Verbal corrections, yelling, punishment, or your own anxious behaviour may further aggravate your dog’s barking and anxiety.
Avoid leaving the puppy outdoors unsupervised for long periods. It may be stimulated to bark by passing stimuli (other dogs, strangers) or may bark to attract your attention. Opening the door or going out to the dog, even to settle the dog down, will only serve to reinforce the barking behaviour.
