Barking is the nature of every dog. Dogs at home will bark as soon as they hear a sound. The owner can train and teach the dog. When the dog barks, call its name and interrupt it. Yell to tell it that someone is passing by and not entering the home. Take your dog out more often and be exposed to different environments so that the dog can adapt to different sounds and reduce the dog's unfamiliarity with things.

Tip:

Dogs have very sensitive hearing. When training a dog, give the dog more interactive praise and let the dog exercise more. The dog will stop when he is tired. If the dog barks, prepare some toys to distract it.
