The St. Bernard dog is kind, friendly, and enjoys the company of children. It is loyal to its owner, easy to train, and adept at saving lives. In Denmark, whenever a blizzard comes, they show their skills and rescue countless people in distress in the vast snowfields.

Voice The St Bernard has a keen hearing. But for sudden loud sounds, such as lightning thunder, the roar of planes, firecrackers, etc., many St. Bernard dogs are afraid of firecrackers during the Chinese New Year in Chengdu. Some St. Bernards show a sense of fear. Such as escaping to a safe place with the tail tucked, crawl into the house or tuck the neck into a narrow place; or if there is no interest in food or even refusal to eat, even blame is ineffective. And as long as the sound persists, the St. Bernard's mood cannot be stabilized, and the owner's comfort will have little effect. The St. Bernard's body also undergoes a series of changes, such as increased breathing, tremors, increased pulse, and increased body temperature. The female Saint Bernard dog may also have a tragedy of eating her baby soon after giving birth.

Death Dogs have a strong fear of death. This mainly refers to the death of the same kind. The smell emitted by the dog after death has a strong terrifying stimulus to the living dog. Even the most intimate dog companion and its offspring dare not approach, showing the fear of standing fur, retreating step by step, trembling all over expression. Some dogs also show a fear of leather odors, and they also hate shoes made of leather, which may be due to the smell of other animals remaining on the leather.

Light and Fire Many St. Bernards have a fear of flashes and fire. Such as fireworks, searchlights, and even the moment when a match is lit when smoking, it will also frighten the St. Bernard. Like the fear of sound, it is an instinctive alert of the St. Bernard to natural phenomena. But unlike sound, when light and fire appear in the St. Bernard's territory, it will bark carefully around it, so there are many stories of St. Bernard dogs calling the fire alarm. Some St. Bernards also hate fireworks so much that they will stamp out cigarette butts thrown on the ground with their feet. Strengthening the training of these actions can give the St. Bernard dog guarding the warehouse a very useful skill.

Of course, sometimes the St. Bernard's fear is caused by its incomprehensible phenomenon. Such as specimens without life breath but with life forms, toys that can make sounds of birds and animals and move, doors that are blown by the wind when no one is there, open umbrellas, etc., all make St. Bernard dogs difficult to understand and feel. Creepy.
