Dog communication refers to boy movements and sounds dogs use to send signals to other dogs, and other animals (usually humans). Dog communication comes in a variety of forms. Dogs use certain movements of their bodies and body parts and different vocalizations to send signals. There are a number of basic ways a dog can communicate. These are movements of the ears, eyes and eyebrows, mouth, head, tail, and entire body, as well as barks, growls, whines and whimpers, and howls.
