Dog body language: recognising stress signals
Yawning without being tired, lip licking, looking away, freezing: here's how to read your dog's early stress signals, before he has to growl.
Dogs communicate mainly through body language, not sound, and stress often shows up more subtly than barking or growling: think yawning without being tired, licking the nose or lips, a low tail carriage, or looking away. Learning to recognise these signals helps you prevent escalation and give your dog rest in time.
Why body language matters so much
Dogs often give early, subtle signals of discomfort well before they growl or bite. By recognising these signals, you can step in in time (create distance, change the situation) instead of waiting until your dog feels forced to communicate more loudly.
The communication ladder: from subtle to clear
A useful model for understanding this is the “ladder of aggression”, developed by veterinary behaviourist Kendal Shepherd: a rising sequence of signals a dog moves through as tension increases, or as earlier, more subtle signals get ignored. From bottom to top, roughly:
- Geeuwen, knipperen, neus likken
- Wegkijken
- Lichaam wegdraaien, zitten, een poot opheffen
- Weglopen
- Kruipen, oren naar achteren
- Ineengedoken staan, staart tussen de poten
- Liggen met blootgestelde buik (uit angst, niet uit ontspanning)
- Verstijven, staren
- Grommen
- Happen (zonder te bijten)
- Bijten
The higher up the ladder, the clearer the signal, but also the further your dog has already been pushed. The goal is always to respond as early as step 1 or 2, not to wait for growling. A dog that learns the lower rungs get it nowhere will skip them faster next time.
Early stress signals: Rugaas’ “calming signals”
Norwegian dog trainer Turid Rugaas called these early signals “calming signals”: behaviour a dog uses to reduce tension, both in itself and in whoever or whatever is causing it. They’re subtle, so they’re often missed:
- Yawning outside the context of tiredness.
- Licking the lips or nose with no food nearby.
- Looking away or turning the head aside.
- “Whale eye”: the whites of the eyes become visible while the dog keeps its head turned away, a clear sign that something in the environment is causing tension.
- Freezing or stopping still for a moment.
- Panting without exertion or heat.
- Scratching itself outside of an actual itch.
- Sniffing the ground or walking in a curve around something.

Clearer signs of tension
- A low or tucked tail.
- Ears flattened back.
- Growling, this is communication, not “naughty” behaviour, and should never be punished (that only teaches a dog to skip the warning next time).
- A stiff, “frozen” posture right before a reaction.
Relaxed body language, for comparison
A relaxed dog has loose muscles, a neutral to gently wagging tail, an open mouth with relaxed breathing, and natural, fluid movement, no stiffness.

What do you do if you spot stress?
Give your dog space and time: remove the trigger if you can (for example, put distance between your dog and another dog, or a busy crowd), don’t force interaction (“he just needs to get used to it” backfires with real stress) and reward calm behaviour. If stress persists in specific situations, guidance from a dog trainer or behaviourist can help.

Frequently asked questions
Does a wagging tail always mean a dog is happy? No, the context, height and speed of the wag say more than the movement itself; a low, stiff wag can actually indicate tension.
What exactly is the communication ladder? A model (known as the “ladder of aggression,” developed by veterinary behaviourist Kendal Shepherd) showing how a dog escalates from subtle to obvious signals when earlier ones are ignored: from yawning and looking away, through freezing and growling, to snapping as a last resort. The earlier you recognise a rung, the less far your dog has to escalate.
What is “whale eye”? The whites of the eyes becoming visible while the dog keeps its head turned away, a clear sign a dog is tense about something in its surroundings, even while the rest of its body stays still.
Should I punish my dog for growling? No, growling is a warning signal; punishing it only teaches the dog to skip that warning next time.
What’s the difference between a tired yawn and a stress yawn? Context is what matters: yawning with no reason to be sleepy, often in a tense or new situation, points more to stress.
When should I seek professional help? If you notice repeated, persistent stress signals in specific situations, or if you’re unsure how to respond yourself.
