Anxiety in dogs: 5 common causes and how to manage them without medication

And then your dog changes. He trembles. He pants. He hides. Sometimes he barks for hours. Sometimes he shreds cushions. Sometimes he licks his paws raw.

This is not a quirk. This is not spite. This is anxiety — a completely natural physical reaction that, in normal measure, is a survival mechanism. In a daily dose, it becomes a problem that needs solving.

The good news: in most cases, anxiety in dogs does not need medication. It needs understanding, the ability to recognise the early signals, and the right tools. In this article we look at the 5 most common causes — and at what actually helps. According to the research, not according to the marketing.

Recognising anxiety in dogs: physical and behavioural signals

Your dog does not talk. He communicates with his body — and often long before we notice.

The most common physical signals of anxiety in dogs are:

• Trembling, even when he is not cold
• Heavy panting, when it is not warm and he has not just been running
• Increased salivation or drooling
• Dilated pupils and a “fixed” stare
• Low-carried tail or a permanently tucked tail
• Flattened ears, even in completely harmless situations

The behavioural signals are just as clear:

• Repetitive barking with no identifiable trigger
• Compulsive licking of paws, flanks or muzzle
• Destructive behaviour when left alone (furniture, shoes, cushions)
• Fleeing or hiding in tight spaces (under the bed, behind the sofa)
• Loss of appetite linked to specific events
• Repeated yawning without being tired — a classic stress signal

It is important to distinguish two forms:

• Acute (situational) anxiety: triggered by a specific event (a thunderstorm, a car journey, a vet visit) and gone once the event is over.
• Chronic anxiety: a lasting state of alert, with symptoms even without an identifiable trigger.

The first can be managed. The second often needs the guidance of a veterinary behaviourist.

The 5 most common causes of anxiety in dogs

1. Sudden noises: thunderstorms, fireworks, building work

Your dog's hearing is around four times more sensitive than ours. He picks up frequencies up to 65,000 Hz; we stop at 20,000. A thunderstorm is not, for him, the sound you hear — it is an explosion of amplified sound waves that he cannot locate in space.

What you can do right away: create a clearly defined safe place (an interior room, away from the windows), leave the TV or music playing in the background to mask the low frequencies of the thunder, and avoid excessive comforting (that only reinforces the idea that there really is danger).

What helps in the long run: gradual desensitisation using thunderstorm recordings at slowly increasing volume, paired with positive experiences (food, play).

2. Car journeys

It is not only motion sickness. It is a combination of three factors: unpredictable movement, loss of control over space, and a negative association in memory (if the car means “vet” or “away from home”, your dog remembers).

Typical signals: heavy salivation, vomiting, intense panting, vocalising, constantly sliding back and forth in the vehicle.

Common mistakes: using the car only for vet visits, long journeys without gradual habituation, unsafe positions (front passenger seat without a dog seat belt).

What works: short positive trips (5 minutes, the park, back home), a securely anchored crate or dog harness, partially covering the window if he is very reactive.

3. Vet visits

Your dog remembers. If the last visit involved pain, restraint or fear, the next one starts in the waiting room — not on the examination table.

What you can do: habituation through courtesy visits with no treatment (walk into the practice, get a treat from the vet, leave again), deliberate management of the waiting room (bring a blanket that smells of home), and controlled breathing on your part (your dog takes on your emotional state).

4. Separation anxiety

This is the most underestimated cause — and the one most often confused with boredom. The difference is clear:

• Boredom: the dog chews shoes, pushes cushions around, causes creative damage. But he relaxes as soon as he has something to do.
• Genuine separation anxiety: the dog becomes stressed before you leave, howls for hours, may urinate or defecate indoors, and can injure himself trying to escape.

Telling the two apart is decisive. Boredom is solved with occupation. Separation anxiety needs a structured desensitisation protocol — often with the support of a behaviour professional.

5. Changes in the environment

A house move, a new family member (human or animal), the extended absence of someone in the household, a change in the owner's work rhythm. For a dog, the stability of his pack and of his space is fundamental.

Normal adjustment time: 2 to 4 weeks. If it takes longer and the symptoms do not ease, targeted intervention is needed.

Natural remedies for anxiety in dogs: what actually helps

Olfactory stimulation with essential oils

A dog has around 220 million olfactory receptors. A human has 5 million. For a dog, smell is not a secondary sense — it is the main sense through which he makes sense of the world.

Which means: targeted olfactory stimulation is one of the most direct ways to influence a dog's emotional state. Some essential oils, at safe concentrations and properly diluted, have a documented relaxing effect:

• Lavender (Lavandula Angustifolia) — the best studied oil, with evidence of less trembling and less vocalising in shelters
• Sweet orange (Citrus Sinensis) — relaxing effect, lower heart rate
• Frankincense (Boswellia Carterii) — traditionally used as grounding, with more recent studies on its effect on cortisol levels
• Roman chamomile — muscle relaxing, with a mild but long-lasting effect

⚠️ Important note: never use undiluted pure essential oils, and never oils that are toxic to dogs (tea tree, eucalyptus, cinnamon, pine, citrus oils at high dosage on the skin). Concentration and carrier base (a vegetable carrier oil) decide whether an oil relaxes or irritates.

If you are looking for a ready-to-use solution formulated on exactly this logic and at safe concentrations: TranquiDog Roll-On was developed for precisely that — lavender, sweet orange and frankincense in a jojoba oil base, applied in 5 seconds, effect after a few minutes.

Routine and predictability

Feeding, walks, sleep, play: a dog is better off when his internal clock matches the household's. A fixed routine lowers baseline cortisol and reduces the reaction to outside stimuli.

You do not have to be accurate to the minute — what matters is reliability in the daily rituals.

Physical and mental exercise

A tired dog is a relaxed dog. But a 20-minute walk is not enough for that.

Anxious dogs need at least:

• 45 to 60 minutes of real physical activity a day (walking, running, playing)
• 15 to 20 minutes of mental work (puzzle games, snuffle mat, filled Kongs, scent work)

Mental work tires a dog more than physical work — and with anxious dogs it often works better.

Touch and steady pressure

Steady sensory pressure (from a Thundershirt, for instance, or close-fitting elastic shirts) shows a measurably lower heart rate in trials with noise-anxious dogs. It works in around 60 % of dogs — worth a try.

The same logic applies to slow, extended touch from you: slow, long stroking movements on non-arousing areas (the sides of the ribcage, behind the ears). No quick scratching.

Music for dogs

Studies at the University of Glasgow showed a measurable reduction in stress indicators in dogs exposed to classical music and reggae. Certain tracks, such as those in the Through a Dog's Ear series, were composed specifically with canine hearing in mind.

It does not replace the other measures, but in combination it strengthens their effect.

When natural remedies are not enough: warning signs for a vet visit

Honestly: there are cases where a natural remedy is not enough — and where it would be a mistake to rely on smell or routine alone.

Contact a veterinary behaviourist if:

• the anxiety affects eating, sleeping or toileting for more than 2 weeks
• the dog injures himself (licking until it bleeds, biting himself)
• there are incidents of fear-related aggression
• the separation anxiety triggers extreme destructiveness or dangerous escape attempts
• you see no improvement at all after 30 to 45 days of consistent measures

The vet can prescribe a structured behaviour therapy and, in certain cases, targeted, time-limited medical support. There is nothing wrong with medication when a professional prescribes it — it is a tool, not a defeat.

Frequently asked questions about anxiety in dogs

Can I give my dog valerian?

Valerian has documented relaxing effects in dogs too, but human dosages and preparations are not suitable for them. Dedicated veterinary products exist. Talk to your vet before giving it, because valerian can interact with other medication.

Do synthetic pheromones like Adaptil really work?

Adaptil is a synthetic pheromone (DAP, Dog Appeasing Pheromone) that mimics the one a bitch releases while nursing. The clinical evidence is mixed: it works in some dogs and not in others, and usually rather mildly. The difference from the essential-oil approach is fundamental: pheromones act on specific receptors, general olfaction on sensory and associative responses. The two are not mutually exclusive.

How long does separation anxiety last in a puppy?

A certain degree of separation anxiety is normal in the first 3 to 4 months of life. If it persists beyond month 6 or intensifies, it should be addressed with a dedicated protocol — the earlier, the better the results.

Are some breeds more prone to anxiety?

Yes. Working breeds with a high need for human closeness (Border Collie, Australian Shepherd, Labrador, Golden Retriever, Cocker Spaniel) are statistically more often affected by separation anxiety. Toy and miniature breeds are more sensitive to noise. Genetics, however, is only a predisposition — the environment makes the difference.

Can anxiety in dogs be prevented?

To a large extent, yes. Early socialisation (weeks 3 to 14), gradual habituation to varied stimuli, step-by-step training to be alone, and a stable routine from an early age. A dog well socialised in its first months rarely becomes an anxious adult dog.

In short

Anxiety in dogs is a real problem, but in the vast majority of cases it can be managed without medication. Three things are needed: recognising the early signals, understanding the specific cause, and using the right tools — not the ones with the loudest marketing.

Smell is one of the most powerful tools, because it addresses the dog's dominant sense. That is exactly why we developed TranquiDog — a roll-on with lavender, sweet orange and frankincense, formulated in our Italian laboratories, following the same philosophy we have applied to sport horses for years: pure ingredients, safe concentrations, visible results.

You apply it in 5 seconds to the chest, the ears or the collar. After a few minutes your dog is calmer — without medication, without sedatives, without compromises.
