The dog doesn’t talk, but constantly communicates through its body. Learning to read these signals can prevent bites, misunderstandings, and help you understand when the dog is happy, stressed, or scared. Let’s look at the 10 fundamental signals.

1. The Tail

The most obvious signal, but often misinterpreted.

  • High, still tail: alert, possible aggression
  • High tail wagging with quick small movements: excitement (sometimes aggressive)
  • Wide wagging of a high tail: happy, confident
  • Tail level with the back, relaxed: calm
  • Low tail, between the legs: fear, submission
  • Fluffed tail: alarm

Myth debunked: "Wagging tail = happy" is false. The speed and height are the true indicators.

2. The Ears

They vary by breed (erect, floppy) but the principle is the same:

  • Ears forward: attention, interest
  • Arrow-shaped ears back: fear
  • Ears flat against the head: extreme stress
  • Neutral ear position: relaxed

3. The Eyes

  • Soft gaze: relaxed
  • Staring gaze, dilated pupils: alarm/aggression
  • "Whale eye" (showing the whites of the eyes): high stress, fear
  • Half-closed eyes: deep relaxation, trust
  • Averted gaze: avoiding conflict

4. The Mouth

  • Slightly open mouth, soft tongue: happy, relaxed
  • Tightly closed mouth: tension
  • Curled lips (showing teeth): imminent aggression
  • Out-of-context yawn: stress, calming down
  • Licking lips without food: a sign of stress

5. The Posture

  • Upright body, weight forward: confidence, possible aggression
  • Low body, weight back: fear
  • Bowing (front legs down, back legs up): invitation to play
  • Stiff shoulders, immobility: maximum alertness
  • Relaxed body, soft hips: calm

6. The Fur

  • Ruffled fur on the back (piloerection): alarm, fear, excitement
  • Soft fur: normal state

7. The Vocalizations

  • High-pitched, repeated barking: alarm/request
  • Deep bark: warning
  • Howling: distance communication (Husky, Beagle)
  • Whining: discomfort, request
  • Growling: never punish, it’s a valuable warning
  • Yelp: pain

8. The Breathing

  • Panting: hot, excitement, pain, stress
  • Silent breathing: normal
  • Long sigh: relaxation (after relieving itself, after play)

9. The "Calming Signals"

Term from Turid Rugaas (Norwegian educator). Signals the dog uses to reduce tension:

  • Averting gaze
  • Yawning
  • Licking lips
  • Suddenly sniffing the ground
  • Turning the head
  • Sitting during a tense interaction
  • Moving slowly

If your dog displays these gestures during an interaction → respect and back off.

10. The "Play Bow"

The play bow: front legs on the ground, bottom up in the air, wagging tail. Clear meaning: "I want to play!" Universal among dogs.

Combinations Indicating Aggression

When you see together:

  • Staring gaze
  • Ruffled fur
  • "Forward" position
  • Curled lips
  • High rigid tail

→ Back off, do not challenge the gaze, speak in a calm voice. Imminent aggression.

Combinations Indicating Fear

When you see together:

  • Tail between the legs
  • Ears back
  • "Whale eye"
  • Trembling
  • Low posture

→ Give space. A scared dog may bite in defense.

The Essentials in a Few Lines

The dog communicates constantly. Often "bites without warning" are bites after dozens of warnings that the owner did not notice. Learning canine language is the first rule for the safety and respect of your dog. 10 minutes of careful observation every day changes everything.
