Originally, this dog breed was to drive cattle to market. However, later on, the dogs were used to pull carts for butchers. They were also police dogs and served in honor of the military. This dog breed is strong and has a loving heart, just like a mythical Greek hero Hercules. Dogs of this type have a broad chest and a heavily-muscled body. When you look into their eyes, you will see warmth, but they display strength and stamina as well.
Their dark brown pools reflect a mellow, intelligent, and fearless expression. Typically they are aloof towards strangers. They have a natural instinct to protect their families and can be ferocious in their defense. They can become dangerous bullies rather than companionable guardians, especially when they not receive early socialization, consistent training and leadership, and a regular job to perform.
They can become overly protective if not carefully bred. They have to be with people, they love people, and if you will left them alone for a long period of time, they may become destructive. They need a couple of 10 to 20 minute walks or playtimes daily.
