A wagging tail means arousal, not happiness — the rest of the body tells you which kind. Dogs narrate their inner life constantly in posture, ears, eyes, and mouth. Learning the vocabulary makes you better at everything else: training, vet visits, introductions, and knowing when your dog needs out.

Learn your dog's “relaxed” first
Soft eyes, loose mouth (often slightly open), weight even across four feet, tail in its natural position — which varies wildly by breed. Ten minutes of watching your dog do nothing is the most useful observation you'll make, because every meaningful signal is a departure from that baseline.
The polite vocabulary: calming signals
Yawning outside of sleepiness, quick lip-licks, sniffing the ground mid-greeting, turning the head or body away, shaking off when dry — these are de-escalations. Your dog is saying “I'm no threat; I'd like less intensity, please.” Seeing them during hugs, photos, or kids' attention is your cue to create space before the dog has to say it louder.
The escalation ladder
Dogs rarely bite from nowhere — they climb a ladder we often ignore: calming signals → stillness and stiffness → whale eye (white crescent showing) → low growl → snap → bite. Every rung is a request. The growl, counterintuitively, is a gift: never punish it, or you teach the dog to skip the warning and go straight to the next rung.
Play, and its punctuation
The play bow (elbows down, rear up) is the invitation; bouncy, exaggerated, role-swapping movement is the confirmation. Good play has pauses — brief check-ins that keep arousal in bounds. Play that loses its pauses, goes silent-and-stiff, or stops swapping roles is heading somewhere else; a cheerful recall and a minute's break resets it.
