The Neo is a tremendous, intelligent, massive and a very, very powerful dog. This breed is a descendent of the Molossus dog (Rottweilers) which was bred by the Greeks. Later the Romans used the Neo in war, arena gladiator dogfighting, and guardians of estates. The breed’s size alone is a deterrent and very intimidating, but most of all it’s undying loyalty as a family dog. The Neo is among the world’s greatest man-stopping guard dogs.
