Origins and history

Of Swiss origin, it is a descendant of the ancient asian Molossian, whose primordial form was embodied by the Tibetan Mastiff. The breed such as we know it today has been selected by the cenobite monks of the Grand Saint-Bernard hospice, its namesake. The monks had been using the breed for a very long time for search and rescue missions in the mountains, as well as for guardianship. Essentially, these dogs served to accompany travellers, and save those lost in the snow. The symbolic little barrel of brandy/ schnapps that they sported around their neck would serve to restore the senses of those lost in action. The most famous of them all was Barry since, in the 14th century, it saved around 40 people from the so-called White Death. The Swiss club was created in 1884, while it was only created in France in 1908.

    Good to know

    The Saint Bernards’ reputation as rescue dogs is well established, but their career is slightly behind them. To wit, breeds of smaller weight are preferred nowadays, in order to facilitate helicopter missions.

      Behaviour of the St. Bernard

      • 33%

        Tolerates solitude

        This dog is not made for being alone for hours on end. It will suffer the absence of its masters, especially if it is recurring and if it hasn’t been gradually conditioned to handle loneliness well.

      • 66%

        Easy to train / obedience

        The large constitution of this mountain molossian requires an early-onset, firm education, upon its arrival within the family. 

        The Saint Bernard puppy must rapidly absord the rules and limitations of life at home. If those basic principles are not integrated as soon as possible, this big dog could quickly become a burden on account of its size. 

        You can also forget about lagging behind this dog on walks- teaching it to walk on a leash, without pulling, will have to be initiated early on, in a positive and consistent manner.

        It is very important to work on the leash walking because, weighing up to 200 pounds, the St. Bernard can quickly overpower its master, which could potentially be dangerous. 

        At times, this big dog can be stubborn, even boar-headed, but a firm and coherent training, fair and respectful of the principles of positive training, will give way to a beautiful master-dog relationship and easy cooperation. 

        Socialisation will also have to be a part of the young dog’s training. Over the course of its first months, it will have to be made familiar with various, more or less stimulating environments, and make various positive, congeneric and inter-specific encounters.

        Barking is this dog’s effective way of deterring anyone from encroaching on its territory if they are not welcome.

        Tendency to run away

        Too much of a loyal guardian to its masters, the ‘Langhaariger Saint Bernardshund’ (its name of origin) does not run away and does not distance itself from its familiar/habitual environment unless it is accompanied by one of the members of its group.

      • 100%


        This dog grows docile with age, but it is true that the Saint Bernard pup can prove to be somewhat destructive, especially if it is left alone all day in a confined space, for example.

        Greedy / Gluttony

        This dog eats huge amounts, proportionately to its large constitution, that’s a fact. And it doesn’t stop at that- this is indeed a big gourmand who could use and abuse the generosity (and sometimes naivety) of its masters to beg all sorts of treats out of them.

        Guard dog

        In spite of its gentle nature, the Saint Bernard is a good guardian on account of its significant territorial instinct. Still, it doesn’t know the meaning of the word “aggressivity”, unless it finds that its master or possessions have come under threat. 

        Because of its large size, this mountain type molossian dissuades intruders by its rather imposing presence. Don’t be fooled by the teddy-bear aspect as it can transition to attack mode if he considers it necessary.

        First dog

        Neophyte masters can adopt a Saint Bernard but must be conscious of the significant time investment that they will have to be ready to make to mold this giant into a pleasant companion to everyday life. 

        This dog is not recommended to people who tend to be too permissive our lax in terms of training. You have to be aware of its capacities but also of its limitations because with a dog such as this one, weighing up to a possible 200 pounds, misconduct cannot be tolerated.

          St. Bernard in a flat

          Obviously, given its bulk, the Saint Bernard needs a lot of space in order to develop harmoniously, and thus needs a garden at the very least (even if it loves living inside, at its master’s feet).

          It is not made for flat life and its guardian instinct could prove difficult in the shared space of an apartment building. 

          Its gentle personality could come to adapt to city life, but its physical constitution remains unsuited for it. 

          In addition to this, even with a garden, this big molossian will require daily outdoor walks to strengthen its socialisation, stimulate its sense of smell and expend its energy.

        • 66%

          Need for exercise / Sporty

          The St Bernard is not the most sporty of its category but he nevertheless does require long walks to keep its physical and mental health in check. 

          Intense physical workouts, such as agility training for example, are not recommended for this large-bodied dog though. Its growth is fast and fragile, which means that it shouldn’t be overly stimulated until it reaches 18 months at the very least. 

          Traction sports could appeal to it but you must wait until it is fully grown.

          Travelling / easy to transport

          This giant dog loves spending time with its masters and discovering new environments by their side, however, its large size does not allow it to follow his closes ones everywhere. 

          In public transportation, its size can be a nuisance to other travellers and in a car, the trunk would have to be big enough to accommodate this colossus in decent conditions. 

          Again- these are important factors to consider before adopting a dog of such a large size.

            St. Bernard and cats

            The St Bernard can tolerate the presence of cats in its habitat if it has been accustomed to them since a young age.

            St. Bernard and dogs

            This dog is naturally sociable but if it is not exposed to a quality socialisation from his first months, it can prove to be somewhat savage when it comes in contact with its congenerates. 

            If it has been exposed to a quality socialisation, this dog will be a very pleasant playmate, even if a little rough at times. You will have to choose the dogs it plays with carefully, as they will have to be able to handle the significant mass of this molossian.

            St. Bernard and children

            Being very docile, this dog poses absolutely no threat to children. It is actually considered to be the ideal babysitter, among the very best of the canine world. 

            Having said that, and in spite of its great qualities, it still remains a dog! Some rules of conduct will have to be implemented for the St Bernard to be respected and for the children to be able to communicate with it, and to let it be when necessary.

            St. Bernard and the elderly

            The strength and large size of this dog are incompatible with a sedentary life at the side of potentially fragile people.



            The price of a Saint Bernard depends on its origins, its age, and its gender. You have to count an average of £1015 for dogs registered with the Kennel Club. 

            With regards to the monthly budget, big dog equals big budget. You have to count an average of £80 per month in order to cater to the Saint Bernard’s physiological needs.


            The maintenance of this dog is not complicated but remains proportional to its size. It will have to be brushed on a regular basis. 

            Special care must be attributed to its eyes as well, they need to be kept in check as they have a propensity towards being teary which could lead to they eyelid folding inwards (entropy).


            The Saint Bernard’s hair loss is moderate but increases during times of moult, from autumn through to spring. It is then that it will require a daily brush.

            Nutrition of the St. Bernard

            The Saint Bernard is one of the fastest growing dogs. In fact, it goes from around 13 pounds to a weight of up to 200 pounds in just two years. This implies a fragile growth which must be consolidated with good nutrition. 

            Veterinary supervision is particularly recommended during this phase, in order to ensure that the appropriate rations are being provided to the young dog (be it in terms of quality or quantity). 

            Given the large quantities of food to provide, the rations must be divided into two meals: a light one in the morning, and a more generous one in the evening, in order to encourage a better digestion. Self-service is not an option for this big glutton with a tendency towards being overweight. 

            Dry food (kibble) may be given but it will have to be premium. That means a ban on the widely-available, commercial dog kibble. For homemade rations, it is advised that the vet approve the menus. 

            An elevated bowl will have to be provided for this big dog to spare it from having to bend over too low to eat.

            Health of the St. Bernard

            Life expectancy

            The life expectancy is estimated to 9 years.

            Strong / robust

            Of robust constitution, the St. Bernard does not show much propensity towards any particular illness, but nevertheless remains fragile on account of its large size.

            Withstand heat

            In the summer, he suffers of heat and it is indispensable that his shelter is placed in a shadowed area with fresh water provided and replaced at regular intervals. 
            During such times, the walks must be re-adapted (early in the mornings, and late a night).

            Withstand cold

            The double coat of this dog, whether short or long, endows it with a very good resistance to cold. Back in the day, its robustness and courage are what would allow it to practice search and rescue missions in the snowy mountains.

            Tendency to put on weight

            Quite the eater and not particularly athletic, this dog can easily become overweight if its nutrition is not balanced.
