Dogs are talking constantly. Most people read only the loudest signals — barking, growling, a wagging tail — and miss the quieter ones that come first.
Learning the quiet ones is the single most useful skill in living with a dog.
Read the whole dog
No single signal means anything on its own. A wagging tail on a stiff body means something entirely different from a wagging tail on a loose one.
Look at five things together: eyes, mouth, ears, body, and tail — plus what is happening around the dog.
A relaxed dog
- Soft eyes, blinking normally
- Mouth loose and slightly open, tongue possibly lolling
- Ears in their neutral position for that breed
- Loose, curved body with weight evenly distributed
- Tail at neutral height, relaxed, possibly a slow sweep
- Smooth, easy movement
Early stress signals
These come first, and they are requests for the situation to change. Behaviourists call them calming or appeasement signals.
- Lip licking when there is no food
- Yawning when not tired
- Turning the head away
- Looking away, breaking eye contact
- Whale eye — the whites showing in a crescent as the dog turns their head but keeps watching
- Sniffing the ground suddenly, for no obvious reason
- Slow, deliberate movement
- Shaking off as though wet, when dry — usually a release of tension
- Scratching at an odd moment
- Moving away
A single one means little. A cluster means the dog is uncomfortable.
Escalating stress
- Mouth closed, when it was open a moment ago
- Tension around the lips and eyes
- Panting without heat or exercise
- Ears back or pinned flat
- Lowered body, weight shifted backwards
- Tail lowered or tucked
- Raised hackles — arousal, not necessarily aggression
- Refusing food they would normally take. This is one of the clearest indicators there is
- Trembling
- Sweaty paw prints on a smooth floor
A dog who will not take food is over threshold. They cannot learn in that state, and the answer is distance, not persistence.
The serious warnings
- Freezing. Sudden stillness in an aroused dog is one of the most important signals there is. A dog who freezes has made a decision
- A hard stare that does not break
- A stiff, tall body, weight forward
- Lip lifting, showing teeth
- A low growl
- An air snap — a deliberate miss, which is a dog with excellent control telling you clearly
Never punish a growl. It is a warning, and a dog punished for warning learns to skip it. The next stage is a bite with no warning, which owners then describe as coming out of nowhere.
The tail
Height, speed and breadth all matter.
- High and stiff, fast and narrow: high arousal, potentially confrontational. Frequently misread as friendly
- Neutral height, broad sweeping wag, whole back end involved: genuinely friendly
- Low and fast: worry or appeasement
- Tucked and still: fear or pain
- Held out horizontally, still: attention and assessment
A wagging tail means arousal, not friendliness. “He’s wagging his tail” is one of the most common things people say just before being bitten.
Play versus trouble
Play: loose bouncy movement, play bows, exaggerated gestures, self-handicapping by a bigger dog, frequent role reversals, pauses, and both dogs returning to it voluntarily.
Not play: stiffness, one dog persistently pinning another, no pauses, one dog repeatedly trying to leave and being pursued, escalating pitch, and a dog whose body gets tighter rather than looser.
The consent test for dog play: hold the more enthusiastic dog briefly. If the other dog comes back for more, it is mutual. If they leave, it was not.
The same test for people
Teach children this and it does most of the work:
- Stroke the dog for three seconds
- Stop and take your hands away
- Does the dog ask for more, or move away?
If they move away, the interaction is over.
Things that are not what they look like
A dog rolling over is not always asking for a belly rub. In a tense situation it is appeasement, and rubbing the belly of a dog who rolled out of worry makes it worse. Look at the rest of the body.
A “smiling” dog with lips pulled back horizontally and the whole body low may be showing a submissive grin, which is appeasement rather than happiness.
Raised hackles are involuntary arousal, like goosebumps. Not necessarily aggression.
The guilty look is appeasement in response to your body language, not remorse. Experimental work is clear on this.
Where people get bitten
Most bites to children come from a familiar dog, in the home, with an adult present. The adult was there; they were not watching the dog.
The situations that account for most of them:
- Hugging, which is restraint from the dog’s side
- Approaching or disturbing a sleeping dog
- Approaching a dog who is eating or has a chew
- Taking something from a dog’s mouth
- Leaning over a dog, or reaching over their head
- Cornering a dog who has nowhere to go
- Continuing to interact with a dog who has already asked to stop
Every one of those is preventable by reading the early signals and respecting them.
The habit worth building
Watch your dog when nothing is happening. Learn their neutral — their normal ear position, their normal mouth, their normal tail carriage.
You cannot spot a change from neutral until you know what neutral looks like. Once you do, the difference is not subtle, and most of the time your dog will tell you what they need long before anyone has to raise their voice.
