cadaver scents are readily available for purchase, just like the doe-in-estrus urine scents that deer hunters use
There are "Pseudo Scents" available for dog handlers use. There value is debatable.
Pseudo Scents
Pseudo scents for heroin, marijuana, and explosives have been designed to match measured VOC profiles, yet one study (Marcias et al. 2008) found that dogs did not respond to the pseudo scents. The lack of response by the trained detector dogs indicated a mis-match between the instrument-measured, human-interpreted profile and the dogs recognized scent signature. (The Supreme Court is poised to decide whether a drug dogs training and certification is insufficient to provide probable cause for a vehicle search in Florida v. Harris (Docket No. 11-817), a case on which the Court granted certiorari on March 26. If a dog has been trained using a fallible technique, could it be said to be well-trained?
Although a certification procedure is something of a threshold to assure the dog has some skills, an analysis of the dogs performance history would more fully establish a canine teams capabilities.)
The researchers state that if synthetic training aids were available then the reliability of HRD dogs might increase simply through improved specificity and sensitivity to the trained target odor. It is not clear if the researchers were aware of, or chose not to mention, that there already are pseudo scents, such as Sigma-Aldrichs Pseudo Corpse Scent Formulations. The adoption of pseudo scents would require many standards to be modified to permit use of such scents.
