"Super" Pit Bull: Training The Ultimate Protection Dog

MEET Ace the elite protection dog - who can jump through second-storey windows to take down armed intruders. The three-year-old American pit bull can even recognise a variety of weapons, including handguns and knives, and could 'easily kill a man' if commanded to. Ace is top dog at Dark Dynasty K9s - who specialise in training executive protection dogs for the police, celebrities and billionaire clients around the world. It takes years of training for a pit bull to reach this level and Marlon has been training Ace five times a week for the last three years - as well as constant interaction - at his facility in New Hampshire, USA.
