What behavior might indicate a dog feels threatened?

When a dog turns its head away and backs off, it is displaying classic signs of feeling threatened or uncomfortable. This behavior indicates that the dog is trying to de-escalate the situation and communicate that it does not want to engage, possibly out of fear or anxiety. Dogs often exhibit this behavior as an instinctive response when they feel threatened, as it signals to other animals or humans that they prefer to avoid confrontation.

In contrast, wagging a tail enthusiastically typically suggests excitement or happiness, not fear. Playing with other dogs indicates that a dog is feeling social and secure, while sitting silently at its owner’s feet can suggest trust and comfort rather than an indication of threat. Understanding these behaviors helps in interpreting a dog's feelings accurately and responding appropriately in various situations.
