Growling is a low, guttural sound made by animals, particularly mammals, as a form of communication. It often serves as a warning signal to others, indicating aggression, fear, or territoriality. Commonly associated with dogs, cats, and bears, growling can vary in intensity and duration, depending on the situation and the animal's emotional state. In addition to warning others, growling can also play a role in social interactions among animals. For instance, wolves may growl during pack dynamics to establish hierarchy or assert dominance. Understanding growling can help humans interpret animal behavior and respond appropriately in various situations.
