Anxious dog: recognizing signs of stress and understanding the causes

Why does your dog tremble at every storm, while the neighbour's dog sleeps right through it? Your dog doesn't speak with words, but they express themselves constantly with their body, and their first messages are often subtle. Knowing how to recognize the signs of stress in dogs, then understanding where their anxiety comes from, is the first step to helping them. When you know where the fear comes from, you're better able to choose what soothes it.

Anxiety in dogs is common

If your dog is anxious, you're far from alone. A large University of Helsinki study, published in 2020 and covering thousands of dogs, reports that about 72% of them showed at least one anxiety-related behaviour, such as noise sensitivity or fearfulness. In other words, it's common, and it's nobody's fault.

Part 1: recognizing the signs of stress

A dog rarely goes from "all good" to "panic" all at once. They first send small signals. If no one notices, they escalate: they freeze, growl, try to escape. The sooner you spot their discomfort, the easier it is to help them.

Subtle signals

These are the easiest to miss. Taken one by one, they don't always mean much: context is what counts.

• Licking their nose or lips quickly, when there's nothing to eat.
• Yawning when they're not tired.
• Turning their head or eyes away when someone approaches.
• Lifting a front paw, as if hesitating.
• Shaking off, as if drying themselves, when they're not wet. It's often a way to "release" after a tense moment.
• Suddenly sniffing the ground in the middle of an interaction.

Body language

Watch your dog from head to tail:

• Ears: pinned back or flat against the head.
• Eyes: dilated pupils, averted gaze, or the whites of the eyes clearly visible (often called "whale eye").
• Mouth: closed and tense, or, on the contrary, rapid panting when it isn't hot and they haven't been running.
• Tail: low, tucked between the legs, or wagging stiffly. A wagging tail doesn't always mean a happy dog.
• Posture: body lowered, back hunched, weight shifted back, or, on the contrary, a frozen, tense body.
• Trembling and sudden shedding during a stressful moment, like at the vet.

Changes in behaviour

Stress also shows in what your dog does, or no longer does:

• they hide, isolate themselves or follow you everywhere like a shadow;
• they bark, whine or howl more than usual;
• they destroy things or scratch at doors, especially when alone;
• they relieve themselves in the house even though they're house-trained;
• they refuse a treat they normally love;
• they repeatedly lick or nibble a paw;
• they sleep poorly, pace in circles or can't settle.

A dog who destroys things while you're away isn't getting revenge. They're expressing distress. Punishing them will only add to their stress.

Passing stress or a problem to watch?

All dogs experience stress from time to time. A dog who yawns at the vet, then goes back to normal in the car, is nothing to worry about. What should get your attention:

• signs that come back often or last;
• reactions that get stronger over time;
• a sudden change in behaviour, with no apparent reason.

In these cases, see your veterinarian. Pain, a digestive problem or another medical condition can be hiding behind signs that look like stress.

Part 2: the 8 most common causes of anxiety

1. Genetics and temperament

Some dogs are born more sensitive than others. Breed, bloodlines and the parents' temperament play a role. A naturally cautious dog will need more time to get used to new things, and that's okay.

2. Lack of socialization as a puppy

The first months of life are a period when the puppy discovers the world. If they meet few people, other dogs, sounds and different places during this period, they may find these things worrying later on. This is often the case for dogs adopted after a difficult start in life.

3. A bad experience

An attack by another dog, a fall, a particularly violent storm: a single event can be enough to create a lasting fear, especially in an already sensitive dog.

4. Separation

Some dogs have a very hard time being alone. They bark, whine, destroy things near doors or relieve themselves in the house when you leave. Separation anxiety sometimes appears after a change: going back to the office after a vacation, a move, a family member leaving.

5. Loud noises

Storms, fireworks, construction, snowblowers: dogs hear sounds we don't even notice. Loud, unpredictable noises are among the most frequent triggers.

6. Changes in their life

A move, a baby, a new pet, a disrupted schedule: dogs are creatures of habit. When their landmarks shift, they can lose their sense of security.

7. Not enough exercise or stimulation

A bored dog builds up energy. This frustration sometimes looks like anxiety: restlessness, barking, destruction. This is especially true for working or very active dogs.

8. Pain, illness and aging

This is the cause people most often forget. A dog in pain can become nervous, irritable or fearful. In senior dogs, declining vision or hearing or other age-related changes can also make them more worried. If anxiety appears suddenly, a vet visit comes before anything else.

Finding the cause in your dog

For two or three weeks, keep a small journal. Every time your dog shows signs of stress, note:

• the time and place;
• what happened just before (a noise, visitors, your departure);
• their reactions and how long they took to calm down.

You'll often see a pattern emerge. This journal will also be valuable for your veterinarian or your dog trainer.

What to do next

In the moment, when you spot signs of stress:

1. Create distance from what's bothering them: another dog, a child who's too insistent, a noise.
2. Give them a way out. Don't hold them back and don't force contact.
3. Stay calm. A steady voice helps them more than agitation.

Then act according to the cause:

• Noises: set up a safe spot and gradually get them used to the sounds, at very low volume to start.
• Separation: practise very short departures, then lengthen them little by little.
• Changes: keep their familiar things and a routine that's as stable as possible.
• Boredom: add sniff walks and search games.
• Socialization: introduce new things from a distance, at their pace, rewarding calm.
• Pain or age: your veterinarian is your first ally.

In short

A stressed dog speaks quietly at first: lip licking, yawning, looking away. Their anxiety rarely has a single cause: temperament, history, environment and health combine. By learning their language and observing them patiently, you'll find what bothers them, and so what can help them.

Frequently asked questions

My dog yawns a lot. Are they stressed?

Not necessarily. Dogs also yawn when they're tired. Look at the context: if they yawn mostly in tense situations, along with other signals, it's probably stress.

Is panting always a sign of stress?

No. Dogs pant after exertion or when they're hot. Rapid panting at rest, in a cool place, however, deserves your attention. If it comes with other symptoms, call your veterinarian.

Are some breeds more anxious than others?

Temperament varies by breed and bloodline, but every dog is unique. A dog of any breed can be anxious, or very calm.

Can anxiety appear in an adult dog?

Yes. A significant event, a life change, pain or aging can bring on anxiety at any age. A sudden change always warrants a vet visit.

Can my own stress affect my dog?

Dogs pay close attention to our movements and tone of voice. Staying calm and taking a deep breath is often a good first step.

Is my dog's anxiety my fault?

No. The causes are many and often beyond your control. What matters is how you support them from today on.
