Name a sign of aggression in dogs.

The identification of growling or baring teeth as a sign of aggression in dogs is accurate because these behaviors are well-documented indicators of a dog feeling threatened, defensive, or ready to fight. Growling serves as an audible warning, signaling to others (including humans and other animals) that the dog is uncomfortable with the current situation. It conveys a feeling of unease and can indicate that the dog might escalate its behavior if it perceives further provocation. Similarly, baring teeth is a physical display of aggression and serves as a visual warning; it shows the dog’s teeth, often accompanied by other body language cues that emphasize its readiness to defend itself if necessary.

In contrast, mid-paced tail wagging typically reflects a neutral or mildly positive emotional state, not aggression. Excessive sniffing of the ground is commonly associated with exploration or curiosity, rather than any aggressive tendency. Friendly barking and jumping usually signify excitement or a desire for social interaction, which does not align with the signs of aggression. Recognizing these distinctions is crucial for understanding canine behavior and ensuring safety for both animals and humans.
