By Chris Pleasance A toddler has been left traumatised after watching his tiny chihuahua puppy get 'torn apart' by a Staffordshire bull terrier. Lawson Morgan-Cockburn, two, was out walking with his mother Sarah Morgan, 26, and their three chihuahuas when their youngest dog, a one-year-old named Bruno, was set upon. Bull terrier Lennox, who was adopted by his owners as a rescue dog a year ago, escaped from a garden before mauling puppy Bruno while Lawson was still holding his lead. Sarah Morgan, 26, says her two-year-old son Lawson has been left traumatised after watching his one-year-old chihuahua puppy Bruno mauled to death in front of him
