Along the lines of the Cane Corso being recreated,... The true Blue Heeler is actually an extinct breed. What people refer to as "Heelers" today are actually Australian Cattle Dogs.
Even the English Mastiff is recreated. The true English Mastiff went extinct during WWII. There was literally not a single one left alive after the war. They recreated it largely from Great Dane and Bull Mastiff stock.
