This is not a Pit Bull. This is a Cane Corso.
The Cane Corso originated in Italy from the Canis Pugnax (the old Roman Molossian). They were used for hunting large wild animals and also as a warrior in battles. For many years they have been companions of the Italic populations-employed as property, cattle and personal guard dog as well as hunters. The Cane Corso's name comes from the Latin "Cohers" which means Guardian and Protector.
In medieval times, the Cane Corso was used primarily on big game. Their power, courage and agility made them especially valuable on wild boar. They were also used on stag and bear at times as well.
