Dogs bark because we humans want them to. Domestication and selective breeding have enabled our dogs to develop their barking powers for many years. Wolves do not yell. Barking was further evolved in dogs to frighten intruders or to aid the owner (i.e., on farms, to assist in gathering the sheep).
Most dogs bark to communicate, get attention, or just to express their enthusiasm. Training and lifestyle choices are critical in educating the dog to communicate with its owner. If you give your dog a treat for barking, he will continue to do so. Determine what your dog is trying to tell you and go from there.
If you have a barking dog, try to find out what he is trying to tell you. If it is due to a need for attention, the best method to interrupt the loop is to wait for him to be quiet before giving him the attention he requires. You promote the barking by recognizing it. Waiting until he calms down will educate him that when he is not barking, he receives attention.
Some dogs are very protective of their territory. They will bark not just at anyone approaching them, but even at those going across the street or on the next block. When he begins barking, the easiest method to stop him is to divert him. Attract his interest with a treat or by playing with him. When the barking cycle is interrupted, it gives the message that being silent is more rewarding.
Taking the time to figure out what your dog is saying can reduce stress for both of you. He'll receive some much-needed care, and you'll get some peace and quiet. It's a win-win scenario for both of you.
