The Rotticorso dog is a new hybrid or designer dog and as such does not have a history to trace his development. For their personality traits we must look to the parent dogs. The Rottweiler ancestry goes back to when the Roman legions crossed the Alps, taking their dogs with them to guard their livestock. They were also used to hunt wild Boar. By the Middle Ages, these dogs had arrived in the German town of Rottweil and had been crossed with local sheepdogs to create the Rottweiler Metzgerhund, otherwise known as the Rotweil Butcher's Dog. Local butchers used these strong dogs to drive and guard their livestock as they made their way between towns. Cattle driving became illegal in the 19th century in Germany, and the hardworking Rottweiler became less popular and declined in numbers. That was until 1914 when they proved their usefulness and bravery when used for the war. It was in the 1930's when the breed came into the United States, and in 1935 the Rottweiler was accepted by the American Kennel Club. Rotties are known for their agile and capable running and jumping prowess as well as their bravery and courage. The Cane Corso Italiano dog is a powerful athletic dog developed to guard property and hunt big game such as wild boar. They are descendants of the Mastiff type dog that were Roman war dogs. A true working dog, they also became a good all-around farm hand and useful dog. The word 'cane' is Latin for dog and is derived from the word 'canis'. Corso is from an old Italian word meaning sturdy or robust. Changes in farming methods brought the Cane Corso dog almost to the point of extinction, as mechanisation replaced the use of working dogs. But in the 1970's dog fanciers began work to rebuild the Corso. They formed a society in 1983 and the breed was recognised in 1996. It was a man by the name of Michael Sottile who imported the first litter of Corso's to the United Stated in 1988, which was followed by a second litter in 1989. The International Cane Corso Association was formed in 1993 and the breed was recognised by the American Kennel Club in 2010. The breed is now governed by the Cane Corso Association of America. For now, it seems this hardy proud breed has a place amongst its peers and has a devoted following of dog owners.
