Dog Behaviour, Body Language and Emotional Wellbeing

Understanding what your dog may be feeling, communicating and trying to avoid

Updated August 2026

Dogs communicate through movement, posture, facial expression, sounds and behaviour. A dog who freezes, pulls away, barks, refuses to walk or becomes unusually restless is not necessarily being stubborn or difficult.

They may be frightened, frustrated, overstimulated, uncomfortable, uncertain or simply unable to cope with what is happening around them.

Understanding dog behaviour does not mean assigning one fixed meaning to every ear, tail movement or yawn. It means looking at the whole dog, the situation and what happened immediately before the behaviour.

This guide will help you recognise possible signs of relaxation, uncertainty, fear, stress and high arousal. It also explains when everyday training may help, when you should contact your vet, and when an accredited behaviour professional may be needed.

Important: This guide provides general educational information. It cannot diagnose a medical or behavioural condition or assess the safety of an individual dog. Sudden, severe, escalating or dangerous behaviour should be discussed with your vet and, where appropriate, a suitably qualified behaviour professional.

Key takeaways

• Behaviour is information. It can tell you that a dog wants something, needs space or is struggling to cope.
• Look at the whole dog, the surroundings and what happened before the behaviour rather than relying on one isolated signal.
• Excitement, fear, frustration, pain, tiredness and overstimulation can produce similar-looking behaviour.
• Do not punish growling or other warnings. Stop, create space and consider why the dog felt the need to communicate more strongly.
• Contact your vet about sudden behavioural changes, signs of discomfort or worsening behaviour. Serious or complex problems may also require an accredited behaviour professional.

Dog behaviour is communication

Behaviour is something a dog does. It is not a reliable description of their personality or intention.

Words such as naughty, dominant, stubborn, aggressive or hyperactive can sometimes prevent us from asking more useful questions.

Instead of asking:

“What is wrong with my dog?”

It can be more helpful to ask:

• What happened immediately before the behaviour?
• Where did it happen?
• Who or what was nearby?
• Was my dog able to move away?
• What did the rest of their body look like?
• Has this happened before?
• How quickly did they recover?
• Could they be tired, frightened, frustrated or uncomfortable?
• Has anything changed in their health, routine or environment?

A dog barking at another dog may be frightened, frustrated, overexcited, protecting space or responding to a previous experience.

A dog refusing to walk may be worried about something ahead, tired, in pain, overwhelmed by the environment or reluctant to leave home.

The outward behaviour matters, particularly where safety is involved. However, understanding what may be driving it gives you a better chance of responding appropriately.

Look at the whole dog and the situation

Individual body-language signals can be useful, but they should not be interpreted in isolation.

A wagging tail does not always mean a dog is relaxed and friendly. Tail movement can occur during excitement, uncertainty, tension and conflict.

A dog may yawn because they are tired. They may also yawn during a stressful interaction. Panting may follow exercise or hot weather, but it can also occur when a dog is worried, uncomfortable or in pain.

Context changes the likely meaning.

Look at:

• The dog’s overall posture
• Whether their muscles appear loose or tense
• Their direction of movement
• Whether they are moving closer or trying to move away
• The position and movement of their tail
• Their ears, eyes and mouth
• Changes in breathing
• Whether they can sniff, eat or respond normally
• What is happening around them
• How their behaviour differs from what is normal for that dog

The Dogs Trust guide to understanding dog body language also emphasises that personality, health, emotional state, previous experiences and the current situation can all affect how a dog communicates.

What relaxed dog body language may look like

A relaxed dog will generally look physically loose rather than rigid.

Depending on the individual dog and their natural body shape, you may notice:

• Soft muscles
• A loose, comfortable posture
• Natural, fluid movement
• A relaxed mouth
• Soft-looking eyes
• Normal blinking
• Ears held in their usual position
• A loosely moving tail
• Comfortable sniffing and exploration
• The ability to look away from things
• The ability to take food normally
• Resting without repeatedly getting up
• Choosing to approach and being able to move away again

Breed, age, physical build and health can affect appearance. Some dogs naturally carry their tails high, have limited facial movement or cannot display the same ear positions as other dogs.

This is why it is useful to learn what relaxed behaviour looks like for your own dog.

Possible signs of uncertainty or mild stress

Dogs often use small signals before resorting to barking, lunging, growling, snapping or trying to escape.

Possible signs of uncertainty or stress include:

• Turning the head away
• Looking away repeatedly
• Lip licking when food is not present
• Yawning when the dog is not tired
• Blinking more frequently
• Holding the ears back
• Lowering the head or body
• Moving more slowly
• Suddenly sniffing the ground
• Lifting one front paw
• Shaking off when not wet
• Closing the mouth suddenly
• Becoming unusually still
• Moving behind their owner
• Trying to increase distance
• Refusing food they would usually take
• Seeking an exit
• Becoming more vigilant or watchful

These behaviours are sometimes described as stress signals, calming signals or displacement behaviours. The terminology is less important than noticing that the dog’s behaviour has changed.

One lip lick or yawn does not prove that a dog is frightened. Look for several signals, changes from the dog’s normal behaviour and what is happening around them.

Signs that a dog may be frightened or significantly distressed

A frightened dog may try to escape, hide, freeze or make the perceived threat move away.

You might see:

• A lowered or crouched body
• A tightly tucked tail
• Ears pulled back
• Wide eyes or visible whites of the eyes
• Trembling
• Heavy panting when the dog is not hot
• Drooling
• Hiding
• Trying to flee
• Refusing to move
• Freezing
• Pacing
• Repeated barking
• Growling
• Baring teeth
• Lunging
• Snapping
• Urinating or defecating through fear
• Becoming unable to respond as they normally would

A dog who rolls onto their back is not always asking for a belly rub. If their body is tense, their ears are back, their tail is tucked or they are trying to avoid contact, they may be asking for the interaction to stop.

Create space and reduce pressure. Do not lean over, restrain, stare at or continue touching a dog who appears uncomfortable.

The RSPCA guide to understanding dog body language provides further illustrations of relaxed, worried and highly uncomfortable body postures.

What does “over threshold” mean?

A dog’s threshold is the point at which a situation becomes more than they can comfortably manage.

Below threshold, a dog may notice a trigger but still be able to:

• Take food normally
• Sniff
• Move away
• Look back at their handler
• Respond to familiar cues
• Make choices
• Recover reasonably quickly

As the situation becomes more difficult, you may see growing tension, scanning, faster breathing, reduced interest in food or increasing difficulty responding.

Once over threshold, the dog may bark, lunge, freeze, flee, shut down or become unable to process familiar information.

This is not necessarily deliberate disobedience. A frightened or highly aroused dog may not be able to respond in the way they can in a quiet environment.

The immediate priority is usually to create safe distance and reduce pressure. Training is more useful after the dog is able to think and engage again.

Excitement, stress and overstimulation can look similar

An excited dog may jump, bark, pull, run around or struggle to settle. A frightened, frustrated, overtired or overstimulated dog may display many of the same behaviours.

High energy does not always mean happiness.

An overstimulated dog may:

• Grab the lead or clothing
• Jump and mouth repeatedly
• Bark sharply
• Become rough during play
• Stop responding to familiar cues
• React strongly to small movements or sounds
• Struggle to take food gently
• Race around without being able to pause
• Remain restless long after an activity has ended

Adding another fast walk, ball-throwing session or exciting game can sometimes make the problem worse.

My guide, Is Your Dog Hyperactive, Overstimulated, Bored or Overtired?, explains how to consider the differences and decide whether your dog may need activity, rest, reduced stimulation or professional help.

You can also read How to Help an Excited Dog Settle After a Walk for practical ways to make the transition home calmer.

Fear, frustration and reactive behaviour

“Reactive” describes a response. It does not explain why the response is happening.

A reactive dog may bark, growl, lunge, pull, spin or snap when they encounter a particular trigger.

Possible reasons include:

• Fear
• Frustration
• Excitement
• Pain or discomfort
• Feeling trapped by the lead
• Wanting to increase distance
• Previous frightening experiences
• Learned behaviour
• Difficulty coping with a busy environment

Some dogs regularly described as difficult are simply awkward but awesome individuals trying to cope with situations they find hard. That does not mean unsafe behaviour should be minimised or ignored.

Barking, lunging and biting can present a genuine risk. Understanding the emotion behind a reaction helps guide appropriate management, but it does not remove the need for safe handling, suitable equipment and professional support where necessary.

The Dogs Trust guide to reactive dogs provides more information about why reactivity happens and the importance of reward-based support.

Trigger stacking and emotional recovery

A dog does not experience each event in isolation.

Several manageable events can accumulate until one final event causes a much bigger response.

For example, a dog may experience:

• An interrupted night’s sleep
• Building noise outside the home
• An unfamiliar visitor
• A rushed departure
• Heavy traffic
• A close encounter with another dog
• A cyclist appearing suddenly
• A child running towards them

The cyclist or child may appear to have caused the reaction. In reality, the dog may have been struggling before that final event occurred.

This accumulation is commonly called trigger stacking.

After a difficult experience, some dogs recover quickly. Others remain tense, restless or more reactive for the rest of the walk or longer.

Recovery may be supported by:

• Leaving the difficult environment
• Creating more distance
• Choosing a quieter route home
• Avoiding additional greetings
• Providing water
• Allowing calm sniffing where safe
• Reducing household noise
• Providing access to an undisturbed resting area
• Avoiding another highly stimulating activity immediately afterwards

Recovery does not always mean asking the dog to perform more behaviours. Sometimes the most useful response is to make the environment easier.

Why pain or illness can change behaviour

Behavioural changes can be an early sign that a dog is uncomfortable.

Pain does not always cause obvious limping, crying or visible injury. A dog experiencing pain or illness may:

• Become irritable when touched
• Avoid being handled
• Struggle to settle
• Wake during the night
• Refuse a normal walk
• Walk more slowly
• Stop jumping onto furniture
• Avoid stairs
• Guard part of their body
• Show less interest in food or play
• Become unusually clingy
• Withdraw from interaction
• React more strongly to dogs or people
• Display behaviour that appears to have no obvious cause

Dental pain, digestive discomfort, itching, joint problems, urinary conditions and other health issues can all influence behaviour.

Contact your vet if your dog’s behaviour changes suddenly, worsens unexpectedly or is accompanied by changes in movement, appetite, sleep, toileting or physical comfort.

Do not assume a sudden change is stubbornness, ageing or a training problem.

Growling is useful communication

Growling can be frightening to hear, but it provides important information.

A growl may mean:

• Please move away
• Stop touching me
• I am frightened
• I feel trapped
• I am guarding something important
• I am in pain
• This situation is too difficult

Never punish a dog for growling.

Punishment may stop the sound without changing the fear, discomfort or conflict that caused it. The dog may then feel that quieter warnings do not work.

If a dog growls:

• Stop what you are doing
• Avoid sudden movements
• Give the dog space
• Do not stare at or confront them
• Move children and other animals away safely
• Consider what happened immediately before the growl
• Avoid recreating the situation until you have suitable advice
• Contact your vet or an accredited behaviour professional where appropriate

A growl should not be ignored, but neither should it be treated as a challenge that must be defeated.

Where there is a bite history, escalating aggression, guarding or risk to a child, seek professional support promptly.

Give dogs space, choice and consent

Dogs should not be expected to accept every person touching, hugging or leaning over them.

Some dogs enjoy physical affection. Others prefer brief contact, interaction only with familiar people or no touching in particular situations.

Signs that a dog may want contact to stop include:

• Turning away
• Moving away
• Becoming still
• Closing the mouth
• Lip licking
• Lowering the body
• Showing the whites of the eyes
• Leaving the area
• Growling or snapping

Consent is ongoing. A dog who approached you can still decide to move away.

When greeting an unfamiliar dog:

• Ask the owner first
• Do not walk directly into the dog’s space
• Avoid leaning over them
• Keep your hands to yourself initially
• Allow the dog to approach if they choose
• Avoid prolonged eye contact
• Do not follow a dog who moves away
• Stop touching if their body becomes tense or they disengage

Read How to Greet a Dog Properly and Please Ask the Dog Before Approaching for more guidance.

Dogs on leads may be unable to move away comfortably. My guide about respecting a dog’s space while they are on the lead explains why an on-lead dog should not be forced into greetings.

Dogs and children

Children and dogs should always be actively supervised by a responsible adult.

Being in the same room is not necessarily active supervision. The adult needs to be close enough to notice changes and intervene calmly.

Children should be taught not to:

• Hug or climb on a dog
• Pull ears, fur or tails
• Take food or toys away
• Disturb a sleeping dog
• Approach a dog who is eating
• Corner a dog
• Follow a dog who moves away
• Put their face close to a dog’s face
• Ride on or sit on a dog
• Enter a dog’s bed or safe resting area

Every dog needs somewhere they can rest without being disturbed.

Small signs of discomfort can easily be missed during noisy or exciting play. If the dog turns away, leaves, becomes tense, closes their mouth, licks their lips or tries to hide, the interaction should stop.

Read my complete guide to dogs and children and the Dogs Trust guidance on dog and child safety.

If a dog has growled at, snapped at or bitten a child, separate them safely and seek professional advice. Do not attempt to test whether the dog will do it again.

Behaviour before, during and after walks

Walks can give dogs valuable opportunities to move, sniff, explore and gather information. They can also expose dogs to traffic, unfamiliar people, other dogs, noise, confined spaces and unpredictable encounters.

During one-to-one walks, I pay attention to:

• Changes in pace
• Scanning or staring
• Sudden stillness
• Reluctance to continue
• Repeated checking behind
• Changes in breathing
• Whether the dog can sniff
• Whether they can take food
• Attempts to create distance
• How quickly they recover after an encounter

A dog refusing to walk should not automatically be dragged forwards.

They may be worried about something ahead, uncertain about leaving home, overwhelmed by the environment, tired or physically uncomfortable.

My guide, What to Do When Your Dog Refuses to Walk, explains what to check and why forcing the dog forwards can make matters worse.

A successful walk is not always the longest walk.

For a nervous, senior, reactive or easily overwhelmed dog, a quieter route with time to sniff may be more appropriate than walking through a busy park simply to cover more distance.

Separation-related behaviour

Dogs can behave differently when left alone or separated from a particular person.

Possible signs of separation-related distress include:

• Pacing
• Panting
• Vocalising
• Scratching at doors
• Destructive behaviour near exits
• Toileting indoors
• Refusing food
• Excessive drooling
• Trying to escape
• Being unable to settle
• Becoming distressed as departure preparations begin

These signs can have more than one cause. A camera recording may provide useful information, but serious separation problems require an individual assessment.

Do not use punishment after returning home. The dog will not reliably connect punishment with something that happened earlier, and it may add further anxiety.

Read Separation Anxiety in Dogs and How to Tell If Your Dog Is Pining for You.

Speak to your vet if distress is severe, worsening or accompanied by self-injury, escape attempts or other health concerns.

When everyday training may help

Training can help teach useful skills such as:

• Responding to a name
• Returning when called
• Walking on a loose lead
• Moving away with the handler
• Settling on a mat
• Waiting at doors
• Leaving unsuitable items
• Wearing equipment comfortably
• Choosing to disengage from distractions

Training should take place at a level the dog can manage.

A dog who is frightened, panicking or highly aroused may be unable to learn effectively. Creating distance and helping them feel safer may need to happen before asking for a trained response.

I use and support calm, reward-based methods. I do not use or recommend:

• Prong collars
• Choke or check chains
• Electronic or shock collars
• Rattle bottles
• Lead jerks
• Physical intimidation
• Deliberate flooding
• Punishment for growling
• Forcing frightened dogs towards triggers

For practical everyday skills, visit my Dog Training Hub.

The training hub focuses on teaching and reinforcing useful skills. This behaviour hub focuses on understanding what a dog may be feeling and communicating.

When to contact your vet

Contact your vet when:

• Behaviour changes suddenly
• Your dog appears painful or uncomfortable
• They react when touched
• Movement, appetite, drinking, toileting or sleep changes
• They become restless at night
• They stop enjoying normal activities
• Fear or reactivity becomes noticeably worse
• A previously sociable dog begins avoiding contact
• An older dog becomes confused or unsettled
• There is severe panic or self-injury
• You are unsure whether a medical condition may be involved

Seek urgent veterinary help if your dog is experiencing breathing difficulty, collapse, repeated seizures, suspected poisoning, serious injury, severe uncontrolled pain or another immediate medical emergency.

Behavioural observations can help your vet. Make a note of:

• When the behaviour started
• How often it happens
• What occurs beforehand
• How long it lasts
• Changes in food, sleep, movement or toileting
• Any recent illness, injury or medication
• Video recordings where these can be obtained safely

Do not deliberately provoke the behaviour to obtain a recording.

When to seek an accredited behaviour professional

Specialist support may be needed where a dog displays:

• Repeated snapping or biting
• Escalating aggression
• Serious resource guarding
• Severe fears or phobias
• Significant separation-related distress
• Extreme shutdown
• Self-injury
• Behaviour that places people or animals at risk
• Behaviour that cannot be managed safely during ordinary care
• Complex behaviour involving possible pain or illness

The behaviour industry is not fully regulated, so titles alone do not guarantee an appropriate level of knowledge or assessment.

Your vet can investigate possible medical contributors and advise about referral. Clinical animal behaviourists commonly work on veterinary referral because health and behaviour can be closely connected.

You can search the Animal Behaviour and Training Council practitioner directory or the Association of Pet Behaviour Counsellors directory.

Choose a professional who uses welfare-led, reward-based methods and is honest about the limits of their role.

How my one-to-one care may support suitable dogs

I have worked professionally with dogs since 2011. I regularly care for dogs who are nervous, sensitive, easily overwhelmed, reactive or simply more comfortable away from group walks.

I describe some of them affectionately as awkward but awesome. That phrase never means ignoring fear, stress, aggression or safety. It recognises that a dog can be wonderful company while still finding parts of the outside world difficult.

My one-to-one approach means:

• Dogs from different households are not mixed
• Walks begin and end at your home
• There are no collection rounds
• There are no cars, vans or travel crates
• Routes can be adapted where practical
• Dogs are given time to sniff
• Forced greetings are avoided
• Distance from known triggers can be increased
• Walks can be shortened where continuing would be unhelpful
• Suitable routines from an existing professional plan can be followed

For a nervous dog, progress may mean leaving home more comfortably, recovering more quickly after a noise or choosing to move away instead of barking.

It does not always mean walking further or greeting more dogs.

My professional boundaries

I provide calm, practical dog walking, pet care and training support

I can:

• Observe and report changes in behaviour during my care
• Adapt a suitable walk or visit
• Provide more space from avoidable triggers
• Follow appropriate instructions agreed with you
• Reinforce suitable everyday routines
• Work alongside an existing veterinary, training or behaviour plan
• Recommend that you seek additional professional help

I do not:

• Diagnose medical or behavioural conditions
• Provide clinical behaviour consultations
• Replace your veterinary surgeon
• Claim to cure fear, anxiety, aggression or reactivity
• Guarantee a behavioural outcome
• Deliberately provoke a reaction
• Take on a dog where the arrangement cannot be managed safely
• Conceal concerns about safety, handling or welfare

Some dogs need a qualified trainer. Others need veterinary investigation or an accredited clinical behaviourist. Calm one-to-one walking can support suitable dogs, but it is not a substitute for specialist help.

Frequently Asked Questions

What is my dog trying to tell me?

Your dog’s behaviour may communicate that they want access to something, want an interaction to stop, need more distance, feel frightened or frustrated, are highly excited or may be physically uncomfortable. Look at the whole dog, the situation and what happened before the behaviour rather than relying on one isolated signal.

Does a wagging tail mean a dog is friendly?

Not necessarily. Dogs may wag their tails when relaxed, excited, uncertain, tense or highly aroused. Consider the speed and position of the tail together with the dog’s posture, facial expression, movement and the surrounding situation.

Why does my dog lick their lips or yawn?

Dogs lick their lips for several reasons, including anticipating food. They yawn when tired, but both behaviours may also appear during stressful or uncomfortable situations. No single signal is enough to determine how a dog feels.

What does it mean when a dog freezes?

Freezing can indicate that a dog is concentrating, uncertain, frightened or preparing to respond. Stop increasing pressure and assess the situation. Do not continue approaching, touching or pulling a frozen dog forwards.

Should I punish my dog for growling?

No. Growling is important communication. Punishing it may suppress the warning without resolving the fear, pain or conflict behind it. Stop what you are doing, create space and seek professional advice where appropriate.

What does “over threshold” mean?

A dog is over threshold when a situation has become more than they can comfortably process. They may stop taking food, become unable to respond normally, freeze, flee, bark or lunge. The immediate priority is usually to create safe distance and reduce pressure.

Is my dog excited or stressed?

Excitement and stress can produce similar behaviour, including panting, jumping, barking and difficulty settling. Look at the dog’s body tension, ability to disengage, response to food, recovery time and what was happening before the behaviour.

Can pain make a dog aggressive?

Pain and physical discomfort can contribute to irritability, avoidance, guarding and aggressive behaviour. A sudden or unexplained change should be discussed with your vet rather than treated only as a training problem.

Why does my dog refuse to walk?

Your dog may be frightened by something ahead, overwhelmed by the environment, reluctant to leave home, tired or physically uncomfortable. Avoid automatically dragging them forwards. Look for other changes and contact your vet if the behaviour is new or accompanied by possible signs of pain.

Do reactive dogs need more socialisation?

Not always. Forcing a reactive or frightened dog into repeated close encounters can make them feel less safe. Some dogs need more distance, carefully managed exposure and an individual plan from an appropriately qualified professional.

Can a dog walker help with behavioural problems?

A suitably experienced dog walker may provide consistent handling, quieter routes, space from triggers and support for agreed routines. Dog walking is not a replacement for veterinary investigation, professional training or clinical behaviour work.

When should I contact a behaviourist?

Seek professional help where behaviour is severe, escalating, involves biting or significant guarding, causes extreme distress or cannot be managed safely. Contact your vet first where pain, illness or another medical factor may be involved.

Understanding before reacting

Dogs cannot explain in words that a situation feels frightening, painful, frustrating or overwhelming. Their behaviour provides the information available to us.

Understanding behaviour does not mean tolerating unsafe situations. It means noticing earlier communication, taking sensible safety precautions and choosing support based on what the individual dog needs.

Sometimes that means training a useful skill. Sometimes it means changing the environment, providing more distance or allowing the dog to rest.

It may also mean contacting your vet or asking for help from an accredited behaviour professional.

If your dog is suitable for calm one-to-one care in Finchley, North Finchley, Finchley Central, East Finchley, Muswell Hill or selected nearby areas, I am happy to discuss what they need and whether I am the right person to help.

Veterinary and behavioural disclaimer: This guide provides general educational information and is not a diagnosis, individual behaviour assessment or substitute for veterinary advice. Behaviour can be influenced by pain, illness, medication and other medical conditions. Contact your veterinary surgeon about sudden, severe or worsening behavioural changes. Where there is aggression, biting, severe distress, self-injury or an immediate safety concern, prevent further access to the situation where it is safe to do so and seek appropriate professional help. Do not deliberately provoke or recreate dangerous behaviour.
