There is no doubt that properly trained dogs can perform impressive feats, using scenting and tracking skills, to discover missing people. It can be more difficult for a dog to follow the trail when too much time elapses between the passage of a lost person, or the dropping and subsequent discovery of an object bearing their scent. Nevertheless, their skills should not be discounted. Dogs are a valuable resource for human searchers, but not a substitute for them.
