: They can detect "volatile organic compounds" (VOCs) released during decomposition, even through feet of soil or underwater. The Training
The most effective tool in any recovery mission isn’t a machine; it’s a nose. Cadaver dogs, or Human Remains Detection (HRD) dogs, are trained to ignore the scents of "living" humans and animal carcasses, focusing solely on the volatile organic compounds (VOCs) emitted by decomposing human tissue. Searching for- Cadaver in-
Unlike a tracking dog, which follows a specific human scent trail on the ground, an HRD dog is trained to detect the scent of decomposition floating on the air. These dogs are not looking for a person; they are looking for a plume of chemicals. They work "off-lead," casting back and forth through a search sector to intercept the scent cone. : They can detect "volatile organic compounds" (VOCs)
