The Ultimate Mastiff was designed to combine what we considered the most desirable traits in the mastiff breeds. This mastiff is on the larger side of medium, bred to patrol the property and be a deterant, as well as hold down intruders until enforcements arrive. They are quiet, and masters of surprise. They have a solid temperament, never vicious or shy, and see no reason to spar with other dogs. They are lower energy, yet ready for guard work. #UltimateMastiff #fictional #breed #dog #mastiff
