Read the whole dog

Communication includes weight distribution, muscle tension, movement, eyes, ears, mouth, facial tension, tail position and movement, vocalisation, breathing, distance, orientation and environmental context.

No single signal has one guaranteed meaning.

A wagging tail does not always mean friendliness. Raised hackles indicate arousal, not automatically aggression. Looking away can reduce social pressure. Lip licking may reflect food anticipation, stress or another context. A closed mouth can reflect concentration or tension. Belly exposure can mean relaxation, invitation or appeasement. A still dog is not necessarily a calm dog. Freezing is important communication and should not be ignored. Growling is information, not disobedience.

Relaxed and able to cope

Possible signs: loose muscles, fluid movement, soft facial expression, normal exploration, ability to disengage, ability to eat, normal breathing, comfortable rest.

Uncertain or seeking space

Possible signs: turning away, lowered posture, slower movement, scanning, paw lift, lip licking, moving behind a person, reduced interaction, seeking distance.

Highly aroused

Possible signs: increased muscle tension, fixed attention, rapid movement, vocalisation, heavy breathing, pulling, reduced response to familiar cues, difficulty disengaging.

Defensive escalation

Possible signs: freeze, hard stare, growl, snarl, air snap, lunge, bite.

Dogs do not always follow one fixed escalation ladder, but quieter requests for space often appear before more obvious defensive behaviour.

Punishing a growl can remove the warning without removing the reason the dog felt unsafe.
