Body Language

Nonverbal communication fascinates most of us animal lovers, and who can blame us for wanting to understand our furry friends? But reading the body language of another species is quite a challenge. Most of us try to translate facial expressions, body postures, tail positions, and other details into signals that make sense in human terms—a strategy that often fails.

Here’s an overview that can help you learn to read your dog’s signals. Look for the clues provided by the look in her eyes, the tone of her voice, the position of her ears and body, and the motion of her tail.

And remember to take into account your dog’s entire body and the situation she’s in—context is everything.

Vocalization

Bark                Territorial call, attention-seeking, anxiety, social needs, or aggression

Whine              Care soliciting, puppies, pain, or frustration

Howl                To Some breeds, this may be the vocal equivalent of marking

Growl              Aggression or distance-increasing signal

Facial Expression

Eyes                Pupils dilated = Nervous, playful, aroused

Ears*              Forward = Alert, interested, happy, relaxed

Flat, backward, sideways = Fearful, frightened, irritable

Swiveling = Attentive, listening to every little sound, alert, vigilant

Mouth            Closed = Relaxed

Open with relaxed lips = Happy, excited

Open tight and showing teeth = Fearful, aggressive

Lip curl or lifting, vertical or horizontal = Defensive aggression

Submissive grin = Appeasement behavior

*Depends on the breed’s natural ear position
