Barking is one of many forms of vocal communication for dogs. People are often pleased that their dog barks, because it alerts them to the approach of people to their home or it tells them there’s something that the dog wants or needs. However, sometimes a dog’s barking can be excessive. Because barking serves a variety of functions, you must identify its cause and your dog’s motivation for barking before you can treat a barking problem
Each type of barking serves a distinct function for a dog, and if he’s repeatedly rewarded for his barking—in other words, if it gets him what he wants—he can learn to use barking to his benefit. For example, dogs who successfully bark for attention often go on to bark for other things, like food, play and walks. For this reason, it’s important to train your dog be quiet on cue so that you can stop his attention-related barking and teach him to do another behavior instead—like sit or down—to get what he wants.
