The Cane Corso (pronounced ) is a large dog breed of Southern Italian origins that is used for personal protection, tracking, law enforcement, and as a guard dog. Cane Corso appear in two basic coat colours: black and fawn. This is further modified by genetic pigment dilution to create 'blue' (grey, from black) and frumentino or formentino (from fawn, where the mask is blue/grey) colours. Brindling of varying intensity is common on both basic coat colours as well, creating Tigrato (black brindle), and Grigio Tigrato (blue brindle).
