Dogs’ sensitive noses are being used for an expanding array of searches. In the photo above, a dog provides assistance on an archaeological dig.

I keep hearing about new ways that the sensitive noses of dogs are being used to help humans. We know they can help people with disabilities and sniff out contraband drugs in airports. I’ve also heard they can detect certain diseases in people before doctors can. And in this story, they are used by archaeologists to find ancient tombs.

Joshua Rapp Learn writes at the Guardian, “The scent-tracking abilities of trained dogs have helped archaeologists discover iron age tombs in Croatia dating back nearly three thousand years. …

“Experts have said that using dogs could be a good way to identify archaeological sites, as it is less destructive than many traditional methods.

“ ‘Dogs’ noses obviously don’t make mistakes,’ said Vedrana Glavaš, an associate professor of archaeology at the University of Zadar in Croatia and the lead author of the study, which was published in the Journal of Archaeological Method and Theory.

“Glavaš had already found a few tombs in a necropolis near the prehistoric hilltop fort of Drvišica, which dates back to the eight century BC. Hoping to find more, she contacted Andrea Pintar, a trainer who works with dogs used for sniffing out graves in criminal investigations. …

“Glavaš first sent the dogs to graves they had dug up the previous year but which were not apparent, without telling the trainers the location.

“ ‘We always use at least two dogs to confirm the position,’ Glavaš said, adding that the second trainer and dog were not told where the first dog and trainer had indicated a grave.

“The canines discovered all three graves, even though the human remains, associated artefacts and surrounding soil had been removed. The area had also been exposed to wind, sun and rain since the excavation.

Glavaš said the porous rock around the excavated soil had probably absorbed enough of the aroma of decomposition that the dogs could still detect it.

“Glavaš then let the dogs loose in an area they suspected more remains could be found, and excavated six new tombs – five of which are described in the recent paper. The dogs were extremely accurate in every case.

“The tombs consist of small stone burial chests in the middle of walled stone circles, each about five metres in diameter. Each chest contained small bones such as the fingers and feet of several individuals – perhaps several generations from the same family – along with buckles and other artefacts.

“Glavaš said the people in the site were probably fairly poor due to the harsh, windy climate of the area and the difficulty of growing crops. …

“Angela Perri, a postdoctoral archaeology researcher at Durham University who was not involved in the study, said using dogs to sniff out burials [can] be used in situations where ground-penetrating radar or other techniques may not work. …

“Perri, who studies the ancient history of how humans first began to domesticate and use dogs, said the technique was just the latest in humans’ long history of using dogs as biotechnology. ‘We’re still finding new ways of having dogs help us,’ she said.”
