The Greater Swiss Mountain Dog (German: Grosser Schweizer Sennenhund or French: Grand Bouvier Suisse) is a dog breed which was developed in the Swiss Alps. From the litter, puppies who were likable and looked suitable were chosen. Because of this strict selection, and because puppies were often kept in their original neighborhood, the appearance and character of the dogs remained stable. Practical matters were important when selecting the dog and dictated appearance. It isn't known how much attention was given to colors, but it is possible that irregularly or asymmetrically marked dogs were considered less desirable. Although Heim has said that the big butcher dogs, Metzgerhund, became extinct after foreign imports became more popular, there is speculation over whether farmers would get an expensive foreign dog. In 1889 an International Dog Show was held in Winterthur, northern Switzerland; various Sennenhunde were exhibited.
