How to Treat Separation Anxiety in a St. Bernard
St. Bernards are gentle giants with a naturally patient and watchful temperament, making them excellent family companions—but their size, strength, and slower maturity can work against them when separation anxiety develops. Unlike high-energy breeds that may act out destructively, anxious St. Bernards often panic when left alone, leading to excessive drooling, whining, or destructive behavior despite their typically calm nature. This advanced desensitization guide leverages the breed's trainability (3/5) and low barking tendency (2/5) through slow, incremental exposure to alone time. With their moderate exercise needs (45 minutes daily) already met, you can focus entirely on building confidence and emotional resilience using only positive reinforcement—the most effective approach for this sensitive, people-oriented breed.
Step-by-step
- 1
Establish a consistent daily routine and exercise schedule
St. Bernards thrive on predictability. Exercise your dog for a full 45 minutes each morning (walks, light play) to tire them moderately and reduce baseline anxiety. Follow with a meal, then quiet time. Predictable routines signal safety and help their slower-maturing minds understand what to expect, making departure less scary.
- 2
Create a safe, comfortable alone space
Choose a smaller room or crate (if crate-trained) rather than the whole house—confinement reduces overwhelm for anxious giants. Add familiar bedding, a long-lasting chew or puzzle toy, and ensure the space is cool and quiet. A white noise machine can mask external triggers that might spike their watchful nature.
- 3
Practice micro-departures with rewards
Begin by closing the door between you and your St. Bernard for just 30 seconds while they're calm and occupied with a treat. Return before anxiety builds, give quiet praise (not excited greetings), and repeat 5–10 times daily. Gradually extend to 1 minute, 2 minutes, then 5 minutes over 2–3 weeks. Their trainability improves with consistent, patient repetition.

Use high-value treats and puzzle toys strategically
Long-duration chews (bully sticks, yak chews) and puzzle toys should appear only when you depart, creating positive associations with alone time. St. Bernards' slower maturity means they may take longer to understand the connection, so repeat this pairing daily for weeks. This redirects their watchful attention toward something rewarding.
- 5
Gradually extend departure duration over weeks
Once your St. Bernard remains calm for 5 minutes, increase in small increments: 10 minutes, 15 minutes, 30 minutes, then 1 hour. Track progress in a notebook. Because St. Bernards have low energy and are patient by nature, rushing this stage risks regression—slow progress is reliable progress. A setback means reducing duration and moving forward more gradually.

Desensitize pre-departure cues and practice randomized departures
Stop reacting when you grab your keys or put on shoes; do these actions multiple times daily without leaving. This breaks the anxiety trigger chain. Also, sometimes leave and return within minutes; other times stay home after routine morning exercise. Unpredictability teaches your St. Bernard that departure cues don't always mean long alone time, reducing panic anticipation.
Pro tips
- **Leverage their watchful temperament:** St. Bernards are naturally observant but calm; use this by training them to 'watch' their puzzle toy or chew instead of you. Redirect their attentiveness from your departure to the treat—their patient, focused nature makes this highly effective.
- **Avoid over-exercising before absences:** Unlike high-energy breeds, St. Bernards need only moderate daily exercise (45 min). Exhausting them before departure can backfire, creating dependency on you for stimulation. Stick to consistent, moderate exercise and mental engagement through training instead.
- **Never punish anxiety or make departures emotional:** St. Bernards' gentle, sensitive nature means punishment or emotional farewells worsen anxiety. Leave and return matter-of-factly—no drama, no guilt. This breed responds best to quiet consistency and positive association, not correction.
Frequently asked questions
My St. Bernard drools excessively when I leave. Is this anxiety or normal?+
Excessive drooling during departures is a stress response in St. Bernards and indicates anxiety, even though drooling is normal for the breed. Combined with panting, pacing, or destructive behavior, it signals your dog needs this desensitization program. Monitor whether drooling decreases as you progress through the steps—it's a good indicator of improving confidence.
How long will this training take for a St. Bernard?+
Because St. Bernards mature slowly and have moderate trainability (3/5), expect 6–12 weeks of consistent daily practice to reach 1–2 hours alone comfortably. Some dogs may need 4+ months. Progress isn't linear—be prepared for occasional setbacks, especially if your dog experiences a stressful event. Patience is essential with this breed.
Can I use medication alongside this training?+
Yes. Consult your veterinarian about short-term anti-anxiety medication (like trazodone) to lower your St. Bernard's baseline panic while you train. Medication removes the emotional spike that prevents learning; training addresses the root cause. Combine both for best results, especially in severe cases.
My St. Bernard is a puppy and already showing separation anxiety. Should I wait until they mature?+
No—address it immediately. St. Bernards' slow maturity means anxiety can become a deeply ingrained habit if left unchecked. Pups are actually easier to train than adult dogs. Start with very short micro-departures (15–30 seconds) and let the timeline stretch naturally. Early intervention prevents years of distress.
