Body Language (Dogs)

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 their eyes, the tone of their voice, the position of her ears and body, and the motion of their tail.

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

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
