Barking is the dog's method of communication, but sometimes they bark too much. Many times you can control excessive barking by understanding the potential causes. If your dog barks when you are away from home, try not to make a "scene" when you leave. Leave a radio on for your dog to be comforted by human voices. Dogs might also bark because they need more exercise, have been confined too long or need to relieve themselves. Dogs might also bark because of loud noises outdoors or if they hear other dogs outside. Make sure your dog gets plenty of exercise and playtime.
To train your dog and control his barking, state the command "quiet" in a low voice. Praise him when he obeys. If he continues, clip a leash to his collar, say "quiet." When the dog looks at you, praise him, tell him to sit, help him into sitting position. Offer one treat or kibble of his food and praise to reinforce good behavior.
