What is a 'warning' sign that a dog may bite?

The indication that a dog may bite is best represented by snapping or baring teeth. This behavior is a clear warning signal that the dog is feeling threatened, aggressive, or uncomfortable. When a dog displays this behavior, it is trying to communicate that it is feeling defensive and is prepared to react if it perceives a continued threat. Understanding this warning is crucial for recognizing when a dog is not just acting playful but is in a state of distress or agitation.

Other behaviors such as barking loudly can be part of a dog's normal communication and may not necessarily indicate aggression; it can signify excitement, alertness, or a call to attention. Wagging its tail is often seen as a sign of friendliness and enthusiasm; however, the context is important, as a wagging tail can sometimes accompany aggressive behavior when coupled with other cues. Licking lips can indicate anxiety or submissiveness but does not definitively signal an impending bite. Recognizing the signs that suggest discomfort or aggression is crucial for safety around dogs.
