Italian Mastiff

The Italian Mastweiler is a combination of the Italian Mastiff (also called the Cane Corso) and the Rottweiler. Since both of these dogs are large, your Italian Mastweiler will also be large and should be about 75 to 120 pounds when fully grown. They enjoy working just as much as playing and prefer to be busy at all times. Although the Italian Mastweiler is a loyal and loving pet, they are also excellent guard dogs because of their strength, size, and courage. They do need early socialization and thorough training because they are very strong and can be a lethal force to contend with in the wrong hands.

Italian Mastweiler  Breed History

To know your Italian Mastweiler’s personality and background, you will need to look at the parent breeds’ backgrounds. The Italian Mastiff is also known as the Cane Corso and descends from Roman Molassian war dogs such as the Neapolitan Mastiff. They were originally used as war dogs but after the Roman Empire fell, they were used around the farm as a guard and for hunting game such as wild boar and bear. The breed almost became extinct after World War II. By the 1970s, there were only a few Italian Mastiffs left in Italy and a breeding program was started in 1974 by Dr. Paolo Breber and Giovanni Bonnetti. In the 1990s, the Italian Mastiff got recognition from the International Federation of Kennel Clubs but then their name was changed to Cane Corso. The International Cane Corso Federation was started in America in 1993 and they were accepted by the American Kennel Club in 2010. The Rottweiler has been around since the first century and was bred in Germany from the German Shepherd, Roman Drover Dog, and several different kinds of Mastiffs. It is thought that Roman Soldiers of the 11th Legion of the Roman Empire developed the Rottweiler breed in Wurttemberg, Germany to guard their camps and herd and protect their cattle. Their name came from the town of Rottweil, which was a town in Germany that had many of these dogs. They were kept busy at all times, pulling carts and herding cattle during the day and guarding the camps at night. In the 1800s, the breed began to be less useful because cattle driving was outlawed but butchers started using them to pull carts full of meat and they were nicknamed the Rottweil Butcher Dog or Rottweiler Metzgerhund. They were soon found to be excellent police dogs and were even used as guards during World War I. In 1931, the American Kennel Club noticed and accepted the Rottweiler, where it is still the 8th most well-liked breed in the United States.

Italian Mastweiler  Breed Maintenance

Although the Italian Mastweiler has a short coat, they do shed so you need to brush your dog regularly. A slicker brush or deshedding tool is about the only thing you should need to prevent too much shedding but you may need to brush him more often during shedding seasons. While you are brushing your dog, you should check his skin for injuries or abnormalities and clean his ears and teeth. In addition, you can shampoo your dog once in a while as needed with mild dog shampoo but be sure to dry him thoroughly to prevent him from getting chilled.

Italian Mastweiler  Temperament

The Italian Mastweiler is a pack dog that likes to be active and prefers to be with his family or other pets at all times. They get bored when alone and need to have a strong trainer to know who is the boss. This breed is capable of doing serious physical harm to people and other animals so they need to be trained thoroughly and you have to be firm with him at all times. Never leave your Italian Mastweiler alone with small children or animals and be sure to socialize your dog early and often so they get along with others.

Italian Mastweiler  Activity Requirements

Your Italian Mastweiler loves working as well as playing and prefers to be moving at all times. They need an hour or more of exercise every day and prefer to go for a walk at least once a day. However, be sure to keep him on a leash so he does not chase after other animals. Because they are so strong, it is best to make sure your dog is well-trained before you try to take him for a walk in an unleashed area. Once you lose control of such a powerful dog, it is hard to get it back. They enjoy swimming, running, playing with toys, and going to the dog park.
