Canine identification of a suspect can help police with their inquiries, and evidence of identification is accepted in some courts.[15][31] The most approved method of identification is for the hound to jump up, and place its paws on the subject’s chest.[47][48] In the case of a lost person or a known fugitive identification will not be significant, and in the case of a potentially violent, possibly armed, fugitive a bloodhound handler will not want his dog to approach the quarry for fear of injury to the bloodhound. Many bloodhounds reaching the end of a trail will show no interest in the person they have been trailing, and are difficult to train to identify. Leon Whitney recommended a method of initial training in which identification was the first thing learned,[30] based on giving the young hound a scent-article from someone who walks a very short distance out of sight into a barn, where he stands with a piece of liver, while another person, also smelling of liver, stands nearby. The hound is led along the 'trail', and if it shows an inclination to go to the wrong person it is chastised, but gets the liver if it goes to the right one. When the hound goes to the right person almost infallibly, the number of people is increased, making the choice more difficult, and eventually the brief walks are extended into full trails.[30] @Curionic
