These include visual communication (movements of their bodies and body parts)
auditory communication (vocalizations}
and gustatory communication (scents and pheromones).
Body movements include their ears, eyes, eyebrows, mouth, nose, head, tail and entire body, as well as barks, growls, whines and whimpers, and howls.
Canine communication is a complex system of sign language, vocalization, and even scent cues. These signals reinforce the dog's social position within the group.
