In 1907, the first formal breed standard was adopted, but for a long time at exhibitions the Swiss Mountain Dogs were exhibited without registration numbers and pedigrees.
This breed became popular in other countries, where not only the beauty, but also the working qualities of the Berns were appreciated. Swiss dogs have established themselves as excellent companions, rescuers and even film actors. The Bernese Mountain Dog club was established.
In the middle of the last century, as a result of the mating of the Sennenhund with the Newfauland, herding dogs from Switzerland improved their natural characteristics: they became more phlegmatic and acquired a long coat.
