Dalmatian

The Dalmatian is instantly known by its white coat and dark spots, traced to Croatia and the historical region of Dalmatia. Bred as a hunting dog, it found its lasting role as a carriage dog — trotting alongside horse-drawn coaches and, later, firehouse engines — which is where its reputation for stamina comes from.

The measured build is here. The breed's spotting and its associated deafness risk are facts about the line rather than numbers a catalogue can carry.
