The Drever is a breed of dog, a short-legged scenthound from Sweden used for hunting deer and other game. The Drever is descended from the Westphalian Dachsbracke, a type of German hound called "Bracke". The breed name Drever was chosen through a contest in 1947.
All short-legged scenthounds in Sweden are Drever.
The text only describes Drever but the statement says that any short-legged scenthound in Sweden is a Drever.
