Swiss peasants quickly appreciated the stamina and good-natured nature of these large dogs, adapting them to work in cheese dairies and transport milk along mountain paths. Until the middle of the 19th century, the Sennenhunds regularly grazed cows on alpine lawns, in between working as dairy product carriers, but they were soon pushed out of this niche by St. Bernards. In some remote areas, the descendants of Roman Molossians were still bred, but not so zealously, which is why the famous tricolor color among animals was less and less common.
