Are Bernese Mountain Dogs prone to separation anxiety?

Yes. Berners were bred as Swiss farm dogs working side by side with their people, and they are famously devoted, gentle, and sensitive. That deep attachment is lovely, but it also means many Bernese Mountain Dogs find being left alone genuinely hard, especially if they've had little practice at it.

How long can a Bernese Mountain Dog be left alone?

As a general guide, a confident adult Berner can manage around 4 hours alone, though this is a breed that truly craves company and shouldn't be isolated for long stretches. Puppies need far less, roughly one hour per month of age. Break up longer days with a midday visit so your dog isn't left feeling abandoned.

Are Bernese Mountain Dogs sensitive dogs?

Very. Berners are emotionally sensitive and feel changes in routine or mood deeply, and they don't respond well to harsh handling. That's central to easing their anxiety: keep training and departures calm, gentle, and positive, and never scold a Bernese for being anxious — it damages their trust and makes the worry worse.

Will a second dog help my Bernese Mountain Dog's separation anxiety?

Usually not. Separation anxiety is about your absence specifically, so a second dog rarely resolves it and can add complexity (or a second anxious dog). Work on the underlying anxiety first, and only add a companion if you want one for other reasons.

How to calm a Bernese Mountain Dog with separation anxiety

Bernese Mountain Dogs are the gentlest of giants. Bred on Swiss farms to pull carts, drove cattle, and work shoulder to shoulder with their families, they are sweet, devoted, and never happier than when they’re at your side. That whole-hearted attachment is the charm of the breed — and it’s exactly why being left alone can be so hard for a Berner. If your dog falls apart when you head out, you are not a bad dog parent, and your Bernese is not being difficult. They are anxious, and with a calm, patient plan, that is very fixable.

Is it separation anxiety, or something else?

With high-drive breeds, the first question is usually “are they just under-exercised?” With a Bernese Mountain Dog it’s different. Berners are moderate-energy, gentle dogs, so their distress when alone is rarely about pent-up energy — it’s about your absence and their deep need to be near you.

True separation anxiety is tied specifically to that absence. The tell-tale signs:

Distress that begins within minutes of you leaving — whining, howling, pacing, panting, or drooling.
Destruction aimed at exit points: door frames, window sills, the crate door.
Accidents from an otherwise house-trained dog while you are gone.
A dog who shadows you from room to room and gets visibly worried as you pick up your keys.

The easiest way to confirm is a pet camera on the first 30 minutes after you leave — anxiety shows up fast and looks like genuine panic.

It’s also worth separating true separation anxiety from isolation distress: a dog with isolation distress simply wants company and will settle with any person around, whereas true separation anxiety is about being left by you specifically — the distress continues even if someone else is home.

A sensitive soul

Here’s the thing that shapes everything else with this breed. Bernese Mountain Dogs are unusually sensitive — they read your mood, feel changes in routine keenly, and take harsh words to heart. That sensitivity is central to how you help them:

Keep departures and homecomings calm and low-key; a big emotional send-off winds a sensitive dog up.
Never scold or punish a Berner for anxious behaviour. It doesn’t teach them not to be anxious — it teaches them that your leaving predicts trouble, and it chips away at the trust that makes them feel safe.
Go gently and patiently. A sensitive giant responds beautifully to calm, positive, predictable handling, and poorly to pressure.

A big, gentle dog: gentle exercise, kept cool

A little activity helps a Berner settle, but this is a large, heavy breed, so how you exercise them matters:

Keep it moderate and low-impact. Big and giant breeds are prone to joint issues, and growing puppies especially should avoid high-impact running and jumping until they’ve matured.
Watch the heat. Berners wear a thick double coat built for cold Swiss mountains and overheat easily, so exercise in the cool parts of the day and give them a cool place to settle.
A gentle walk plus a bit of mental work — a puzzle feeder or some calm training — leaves a Berner satisfied without overdoing it.

A step-by-step desensitisation plan

The goal is to make your departures boring and predictable, so your dog relearns that being alone is safe and temporary. Go at your dog’s pace — with a sensitive breed, pushing too fast is the most common and most damaging mistake.

Press pause on scary absences while you train. Try not to leave your dog for longer than they can calmly handle — lean on a sitter, daycare, or a family member — so a panicked day alone doesn’t undo your practice. (You don’t need to drill picking up your keys; those cues lose their power on their own as your dog grows comfortable being alone.)
Start with seconds, not hours. Step outside the door for 10-20 seconds, come back in calmly, and slowly extend the time across many short sessions.
Keep arrivals and departures low-key. No emotional goodbyes, no excited hellos — calm out, calm in.
Give a high-value distraction as you leave. A stuffed or frozen food puzzle creates a positive association with your departure and buys settling time.
Add a calming soundscape. Steady, low-tempo music can mask startling outside noises and give your dog a predictable, settled backdrop — in shelter and kennel studies, dogs played classical music rested more and barked less (Wells et al., 2002; Kogan et al., 2012). Our channel, @TheCozyHound, is made for exactly this, with long-form calming tracks for quiet time. Treat it as a comfort layer, not a cure — the gradual training does the real work.

How long it takes: mild cases often ease within 2-4 weeks of consistent, gentle work. Moderate to severe cases can take several months — that is normal, not failure. Slow and steady suits this breed especially well.

Calming music as a departure cue

The trick most people miss with a calming soundscape: build the association while you are home first, so the music becomes a calm signal rather than a “they’re about to leave” alarm. Play the same playlist during relaxed time together for a week or two, then keep it on as you start your short departures.

Calming aids that can support the plan

These are supportive tools, not a replacement for the training above, and none of them “cures” anxiety on their own. Introduce one at a time so you can see what actually helps your dog, and check with your veterinarian before adding any supplement.

A snug pressure wrap in a large size is designed to help some dogs feel more secure during alone time.
A plug-in pheromone diffuser mimics the calming signals of a mother dog.
A treat-tossing camera lets you check in on your dog remotely and reassure yourself they’re settled.
A cool, supportive orthopedic bed gives a big, heavy dog a comfortable place to rest — and helps a thick-coated breed stay cool.

When to get professional help

If your Bernese Mountain Dog injures themselves trying to escape, panics within seconds of your leaving, or shows no improvement after several weeks of consistent work, talk to your veterinarian or a certified separation-anxiety behaviourist. For more severe anxiety, medication paired with a gentle training plan can make a real difference; your vet can advise.
