In order to make valid statements using statistical methods a large number of measurements on many individuals are necessary. One analysis we undertook a couple of years ago focused on the changing of the Bernese Mountain Dog in the last 100 years and some sex- and size related questions. Although we had about 60 skulls from this breed alone we had only about 7 to 8 per group once we had them separated in male and female, in large and small, in modern and old dogs. One aim of our collections is to be able to document the changes certain breeds make over the centuries. This is the reason we keep on collecting.
