Cadaver dogs: The nose knows something

Abstract

Introduction
“Who let the dogs out.... Woof, woof, woof, woof, woof.... Who let
the dogs out” is a popular song worldwide. However, for us, this
also tells the important and curious aspect of the use of dogs in
forensic crime scene search. Dogs are commonly used to locate or
identify explosives, narcotic substances, and other illegal
materials. In the forensic setting, dogs referred to as cadaver dogs
(sometimes referred to as cadaver detection dogs or human
remains detection dogs, Canis familiaris) are trained specially to
1-3
detect human body odour, and in turn, they signal their handler.
