Introduction
Dogs are masters of non-verbal communication. Unlike humans, who primarily rely on words, dogs communicate through body posture, facial expressions, and movement. To truly understand what your dog is trying to tell you—and to train, care for, and interact with them effectively—you must learn to “speak dog.”
This guide is designed for dog guardians, trainers, shelter workers, and anyone working closely with dogs. It breaks down each part of the dog’s body, helping you interpret their emotional state and intent based on visual cues.
Key Principles of Interpreting Body Language
- No single feature tells the whole story. Always observe the entire body.
- Context matters. A posture or movement may mean different things depending on the situation.
- Baseline knowledge is crucial. Know your dog’s typical behavior so you can detect changes.
- Early signs are subtle. Learning to identify low-level stress signals can prevent escalations.
1. Eyes
| Signal | Meaning |
| Soft Eyes | Relaxed, happy, emotionally calm |
| Hard Stare | Threat or assertiveness, often precedes aggression |
| Hypervigilance | Rapid scanning = arousal or anxiety |
| Avoidance Gaze | Appeasement, conflict-avoidance |
| Whale Eye | White of the eye showing = fear or stress |
| Squinting | Relaxed, submissive, or happy |
2. Ears
| Ear Position | Interpretation |
| Forward/Erect | Alert, curious, or stimulated |
| Relaxed | Neutral, emotionally calm |
| Back | Uncertain, appeasing |
| Tucked | Fearful, stressed |
| Airplane Ears | Confused, unsure how to respond |
3. Brow (Forehead and Eye Area)
| Appearance | Interpretation |
| Relaxed | Neutral, no stress present |
| Furrowed | Curiosity, concern, or stress |
| Tense | Elevated stress or conflict |
4. Coat
| Appearance | Meaning |
| Normal Coat | Neutral, check other signals for context |
| Piloerection (Hackles Raised) | Arousal—can indicate fear, excitement, or aggression |
5. Lips & Mouth
| Mouth Behavior | Meaning |
| Neutral (closed or open, soft) | Relaxed, stress-free |
| Tense Lips | Stress, uncertainty |
| Forward (C-shaped) | Offensively aggressive |
| Pulled Back (V-shaped) | Defensively aggressive |
| Snarling | Clear space-increasing warning |
| Submissive Grin | Appeasement, may signal anxious excitement |
| Yawning | Stress (if contextually inappropriate) |
| Lip Licking | Stress or anticipation (context matters) |
6. Body Posture and Movement
| Posture | Meaning |
| Neutral | Calm, fluid, loose body movements |
| Still | Alert, stalking, or threatening—high arousal |
| Raised (Tall) | Confident, possibly challenging |
| Lowered | Fearful, appeasing, or preparing to pounce (context!) |
| Play Bow | Invitation to play, friendly intent |
| Submissive Roll | Appeasement, communicating no threat |
| Turning/Leaning Away | Disengagement or avoidance |
7. Tail Position and Movement
| Tail Position/Movement | Meaning |
| Vertical (Stiff or Flagging) | High arousal; potential precursor to aggression |
| Up and Wagging | Excitement—check tail speed and stiffness |
| Mid-level (neutral) | Relaxed, friendly, or unsure (if not wagging) |
| Tucked | Fear, stress, or submission |
| Fast Wagging | High arousal; not always happy |
| Slow Wagging | Curious, calm, or unsure |
| Stiff Wagging | Conflict, anxiety, or aggressive tension |
Note: A wagging tail does not always indicate a happy dog. Consider speed, height, stiffness, and the dog’s overall posture.
