Introduction
Dog calming signals are body language behaviors that may help dogs reduce tension, manage uncertainty, or communicate non-threatening intentions. Norwegian dog trainer Turid Rugaas popularized the term and described approximately 30 such behaviors in her book On Talking Terms with Dogs: Calming Signals, including a revised edition published in 2005. Many of these behaviors can also occur for ordinary reasons such as fatigue, food anticipation, exploration, excitement, discomfort, or illness, so they should always be interpreted within the full context. Recognizing clusters of stress-related body language can help owners respond before discomfort escalates.
Direct answer: Behaviors commonly described as calming signals include yawning, lip licking, head turning, freezing, and sniffing the ground. In the right context, they may reflect stress, uncertainty, appeasement, or an attempt to reduce social tension. A single behavior does not prove that a dog is uncomfortable, but repeated signals or several cues appearing together may indicate that the dog needs more space or a change in the situation.

Understanding Canine Stress Communication
Calming signals are a suite of subtle body language cues that dogs use to maintain peace, avoid conflict, and manage social tension. Turid Rugaas developed the concept after decades of observing how dogs communicate with each other and with humans, coining the term to describe behaviors that had previously been scattered across ethological categories like “displacement behavior,” “appeasement signals,” and “conflict behavior.” In Turid’s book On Talking Terms with Dogs, she argues these are intentionally communicative acts, not mere reflexes.
Physical conflict carries risks, so dogs use body posture, movement, and facial expressions to communicate during social encounters. In a 2017 pilot study, researchers observed 24 dogs during 96 off-leash meetings and recorded 2,130 behaviors categorized as calming signals. These behaviors occurred more frequently during interactions and when dogs met unfamiliar dogs, supporting a possible communicative role. Because the study was small and exploratory, the results should be treated as evidence of a possible de-escalation system rather than proof of a fixed or universal language.
The Science Behind Calming Signals
Stress in dogs can affect behavior, heart rate, temperature, hormone levels, and other physiological measures. However, there is not enough evidence to conclude that behaviors labeled as calming signals directly activate the parasympathetic nervous system or reliably cause physiological recovery. These behaviors are better treated as possible indicators that must be interpreted alongside the dog’s posture, environment, health, and recent experiences.
In a 2017 veterinary-exam study, dogs showed increases in lip licking, heart rate, and maximum ocular surface temperature during examinations. Owners were present in both study conditions, but petting and talking were associated with lower heart rate and ocular surface temperature than owner presence without interaction. The study supports the potential value of calm owner contact in that setting, but it does not establish that every yawn, freeze, or lip lick represents stress.
Research on therapy dog welfare found that dogs with more experience in therapy work displayed fewer stress signals like lip licking and paw lifting during sessions, pointing to habituation over time. Current welfare science is pushing beyond cortisol alone, calling for heart-rate variability, thermal imaging, and oxidative stress markers to better validate calming signals’ role in stress modulation.
Context-Dependent Nature of These Behaviors
Context is key when interpreting calming signals in dogs. A dog yawns after a nap; that is fatigue. A dog yawns while a stranger reaches toward its head; that is a calming signal. The same behavior carries different meaning depending on what surrounds it.
Clues that may shift a behavior from ordinary activity to stress-related communication include a stiff posture, lowered or tightly held tail, pinned-back ears, avoidance, repeated behavior, or the presence of a known trigger. In the Mariti et al. pilot study, most of the analyzed behaviors occurred more frequently during close interactions, while ground sniffing and yawning appeared more frequently when the dogs were interacting at a distance. The meaning should be based on the entire situation rather than one isolated movement.
Recognizing calming signals builds trust between dogs and owners because the dog learns its early communications are heard, reducing the need to escalate to barking, lunging, or biting.
Common Calming Signals Every Dog Owner Should Recognize
Dogs have about 30 different calming signals. Below are the ones most frequently observed in research and professional training settings, grouped by the part of the body involved.
Facial and Head Movements
Lip licking and nose licking. A quick tongue flick over the lips or nose may occur during greetings, conflict, food anticipation, nausea, pain, anxiety, or ordinary grooming. Firnkes et al. studied lip licking and looking away during interactions with unfamiliar humans and found that both behaviors may serve as appeasement signals in certain situations. The researchers also stressed that context is essential and found that these signals appeared less often during the most intense threats. Look for surrounding cues such as body tension, avoidance, ear position, gaze direction, and the trigger itself.
Head turning and looking away. Turning the head or body away indicates a desire to avoid confrontation. The movement can range from a slight glance to one side to a full body turn. In Mariti et al.’s data, head turning was among the most frequent calming signals in unfamiliar dog meetings. When one dog stares directly at another, the recipient often turns its head to break the tension.
Yawning. Yawning is a common calming signal in dogs. When a dog yawns during a training session, at the vet’s office, or when a stranger approaches, the behavior serves as tension release rather than sleepiness. The AKC notes that both positive excitement and negative stress can trigger yawning, making context the deciding factor.
Blinking and whale eye. Rapid blinking or showing the whites of the eyes (whale eye) signals anxiety. These are less studied quantitatively but consistently included in professional catalogs of dog body language.
Body Positioning Signals
Freezing or sudden stillness may indicate uncertainty, fear, internal conflict, intense focus, or discomfort. It should not automatically be interpreted as friendly or non-threatening behavior. A stiff freeze can be an important warning that the dog feels pressured and may escalate if the interaction continues. Slow movement may also reflect caution, but the dog’s complete posture and the surrounding situation determine its meaning.
Sitting or lying down during a tense moment is another signal. A dog that sits with its back turned to an approaching stranger or another dog is communicating “I am not a threat.” Rugaas lists this among her catalog of dogs calming signals. The distinction from resting is context: a dog lying down on a sunny porch is relaxing, while a dog that drops to the ground during a confrontation is signaling.
Paw lifting, where a front paw hovers slightly off the ground, appeared less frequently than lip licking in therapy dog research but remained a consistent indicator of mild stress. A puppy meeting a larger dog for the first time will often lift a paw while simultaneously licking its nose.
Reducing body size, crouching, or hunching low to the ground occurred at statistically higher rates in unfamiliar dog encounters in the Mariti study. The dog makes itself physically smaller to communicate submission and peaceful intent.
Movement Patterns
Moving in a curve rather than directly approaching indicates non-threatening intentions. Rugaas emphasizes the curved approach as one of the clearest calming signals dogs use with each other. When one dog walks directly at another dog, the recipient often perceives this as confrontational. A curved path diffuses that perception. This is useful knowledge for dog owners managing introductions and socialization.
Dogs often sniff the ground as a calming signal. When a dog starts sniffing the ground mid-interaction with another dog or person, it is performing a displacement behavior. In Mariti’s data, sniffing the ground increased with greater distance between dogs, suggesting the dog uses this signal to buy time and reduce approach speed.
The play bow, with the front of the body lowered and the rear raised, primarily communicates playful intent and helps clarify that the behavior that follows is part of play. It should not be labeled a calming or stress signal without other clear contextual evidence. A full-body shake may occur after excitement, physical activity, getting wet, waking up, or a tense social interaction, so it is best treated as contextual information rather than proof that the dog has reset its nervous system.
Tail movement also requires context. A low wag may reflect uncertainty, appeasement, or cautious interest. A high or fast wag may indicate excitement, tension, alertness, or high arousal and should not automatically be interpreted as friendliness.
Quick reference of the most reliable indicators: lip licking, head turning, yawning in context, freezing, curved approaches, and ground sniffing. When two or more of these appear together, the dog is communicating stress.
Responding to Your Dog’s Calming Signals Effectively
Recognizing and respecting a dog’s calming signals can improve the human-dog relationship. But recognition alone is not enough; the response determines whether your dog feels safe or learns that its communications go unheard.
Immediate Response Protocol
Use this sequence when you notice repeated calming signals, increasing body tension, or several possible stress cues during training, social encounters, or daily activities:
- Pause and observe. Avoid assuming that one yawn or lip lick proves the dog is stressed. Look at the complete body posture, the environment, and what happened immediately before the behavior.
- Create additional space when needed. If the dog repeatedly turns away, freezes, crouches, attempts to leave, or shows several stress-related behaviors together, increase the distance from the person, dog, object, or environment causing concern.
- Support calm recovery. Allow the dog to look away, move to a safer position, or take a short break. Calm talking or gentle contact may help when the dog actively seeks interaction, but avoid restraining or forcing physical affection.
- Adjust the difficulty. Before continuing, reduce the duration, distance, distraction level, or complexity of the activity. Resume only when the dog’s posture appears softer and the dog can participate without increasing signs of discomfort.
Recognizing possible stress signals can help owners respond before anxiety, fear, or frustration intensifies. The goal is not to stop every activity after one isolated behavior, but to notice patterns and make reasonable adjustments based on the dog’s complete response.
Situation-Specific Strategies
| Scenario | Common Triggers | Response |
| Training sessions | Prolonged duration, poorly timed corrections, commands above current skill level | Shorten sessions to 5-10 minutes; increase reward frequency; end on a success |
| Meeting other dogs | Direct head-on approaches, tight leash tension, crowded areas | Use curved approaches; keep leash slack; let dogs set their own distance |
| Public outings | Strangers reaching toward your dog, loud noises, busy sidewalks | Turn your body sideways to model calm posture; carry high-value treats; create buffer zones |
| Home environment | Guests arriving, routine changes, household conflict | Establish a dedicated safe space the dog can retreat to; maintain predictable schedules; brief all family members on signal recognition |
The right response depends on reading the specific moment. A dog that licks its lips once during a greeting needs a small adjustment. A dog that freezes, turns its whole body away, and tucks its tail needs immediate removal from the situation.
Common Challenges and Professional Solutions
Most dog owners miss calming signals or misread them. The gap between what the dog communicates and what the human perceives is the root of many behavior problems.
Mistaking Signals for Disobedience
A dog that turns away or yawns during training may be confused, distracted, tired, physically uncomfortable, or stressed. The behavior alone does not prove that the dog is defiant or displaying a calming signal. Repeated lip licking, freezing, avoidance, or body tension should prompt the handler to reassess the task, environment, timing, and level of pressure. Clear instruction, appropriate reinforcement, and manageable training steps give the dog a better chance to succeed. If stress-related behavior appears frequently, a professional consultation may help identify triggers and suitable training options.
Missing Subtle Early Warning Signs
Early signals are fast and low-intensity: a half-second lip lick, a brief glance to the side. Mariti et al. recorded over 2,000 calming signals in their study, many of which were subtle enough that untrained observers would miss them entirely. Dogs have about 30 calming signals, and many require practice to spot consistently.
Recording short, naturally occurring interactions can help owners notice brief movements that are easy to miss in real time. Review the footage slowly and note what happened before, during, and after lip licking, head turning, freezing, avoidance, or body stiffness. For dogs with fear or reactivity, a trigger log and video examples may give a qualified professional useful context when discussing training options. Do not stage unsafe encounters or deliberately expose a dog to known triggers solely to record its behavior.
Inconsistent Family Member Responses
When household members respond differently to a dog’s signs of discomfort, everyday interactions may become less predictable. One person may give the dog space while another continues approaching, touching, or restraining it. Children are especially likely to miss subtle body language and should always be supervised during interactions with a dog.
The solution is household-wide education. Professional training programs that include all family members, either through group sessions or video review of the dog’s behavior at home, produce consistent responses. When every person in the home speaks the same language in response to calming signals, the dog’s stress level drops because its environment becomes predictable.
Conclusion and Next Steps
Behaviors commonly described as calming signals can provide useful information about a dog’s stress, uncertainty, appeasement, or social intentions. Lip licking, head turning, yawning, ground sniffing, freezing, and curved approaches are not automatically signs of distress, but they deserve attention when they appear repeatedly, occur around a known trigger, or accompany stiffness and avoidance. Responding by reassessing the situation, reducing unnecessary pressure, and providing appropriate space may help prevent discomfort from intensifying.
Start here:
- Spend 10 minutes today watching your dog during routine activities (feeding time, walks, interactions with family members) and note any calming signals you observe.
- The next time your dog displays a signal during training or a social encounter, stop and give space before continuing.
- Record one interaction with another dog or a new person on video. Review the footage looking specifically for lip licking, head turning, and body stiffness.
- If your dog shows frequent or intense calming signals in daily life, consult a professional trainer who can identify the underlying stressors.
