How many times have we read 'dog walker' finds human remains...when in actual fact the dog has 'led' his owner to the remains during his walk . The dogs are loose and the owner follows the dogs path stumbling upon grisly finds . Dogs that are not trained to detect cadaver it would appear pick up the scent, so imagine a dog trained to ONLY detect cadaver....
