Science of sniffer dogs: Meet the canines that can smell two-year-old blood
Posted 18 Aug 2017
By using this distinct dog unit, a large search area can be screened as a potential crime scene in cases of assault, missing persons, mass disasters or suspected homicides where a body may not be present.
Blood-detection dogs are a recently specialised unit under a broader grouping of scent-detection dogs used by law enforcement.
The dogs' highly sensitive sense of smell can locate a range of target odours including drugs, explosives, human bodies (called "cadavers") and now blood.
