Which mouth shape indicates an offensive threat?

• A. Lips retract vertically exposing only front teeth
• B. Lips retract horizontally exposing all teeth
• C. Mouth closed and relaxed
• D. Mouth open and panting

Answer: (A)

When a dog is signaling an offensive threat, the mouth often communicates a direct, focused warning. Lifting the lips vertically to reveal only the front teeth creates a snarling look that clearly says “back off, I’m prepared to bite.” This specific lip position concentrates the threat on the most recognizable teeth (the canines) and is a classic cue that the dog intends to escalate if its space isn’t respected. Mouths that are closed and relaxed, or open and panting, don’t convey that same imminent bite warning. Exposing all teeth horizontally can appear more intense in some contexts, but it isn’t the quintessential display of an offensive threat. So the vertical lip retraction showing the front teeth best communicates that direct, warning intent.
