Barking becomes a problem when it is triggered by random noises, telephones, passing cars, or loneliness. Because barking is more easily controlled in a young dog, begin corrective training early.
If your dog barks excessively in your presence, give it a firm “no” and, if necessary, a mild, but sudden jerk of the leash or collar. As soon as the dog is quiet, praise and pet it. Follow this procedure consistently until the dog responds to the initial “no.”
The solitary barker More difficult to treat is the dog that barks when left alone. Make sure your attitude is not encouraging anxiety in the dog. As you prepare to leave, chat with the dog reassuringly. Leave the radio on or a familiar object lying around-something that will make the house feel lived in.
If this doesn’t work, try leaving as usual, but wait outside. When the dog barks, reenter, tell it firmly “no,” and jerk its collar if necessary. Praise it when it obeys. Leave again; repeat the procedure several times daily, gradually increasing the time the dog is left alone.
