2 Ways Dogs Are Helping Save the Lives of Elephants

Every year, about 35,000 elephants are killed by poachers for their ivory tusks. The popularity of ivory is skyrocketing, especially in China, where the price for it tripled between 2010 and 2014. Because of this, the elephant population has decreased 62 percent in just a decade, to only about 400,000 worldwide.

If poaching continues, in another 10 years, elephants could very well be extinct.

To help prevent this tragedy, dogs are being trained to use their incredible senses of smell to track poachers and sniff out ivory.

‘Supernatural’ Dogs Track Poachers

When it comes to keeping poachers away from an area, “there is no tool more effective than tracker dogs,” according to the conservation organization Big Life Tanzania.

“Our dogs have tracked elephant poachers for up to eight hours at a time or more, through extreme conditions—heat, rain, wetlands, mountains—and still turned up results,” Damien Bell, the organization’s director, told National Geographic. “They love their handlers, and they do a job until the job is done.”

Up to 24 hours after a poacher has killed an elephant, trained tracking dogs can sniff out the trail to the door of the killer’s house.

“This is a significant deterrent: the poacher knows that nothing he can do will be able to change this,” writes Big Life Tanzania’s co-founder, Richard Bonham, on the organization’s website. “The Maasai in particular are terrified of tracker dogs, regarding them as somehow supernatural in their ability to track them down.”

One of Big Life Tanzania’s rangers, Mutinda, happens to a former poacher himself. He’s especially helpful since he’s familiar with secret trails.

“The real long-term benefit may be the example he is showing to his community through the growing prosperity of his family,” Bonham writes.

“The challenge is to find work and employment for others in his old poaching fraternity, in order to get them to change.”

Sniffing Out Ivory

To train dogs how to sniff out ivory at airports, seaports and border crossings, in 2014 the African Wildlife Foundation (AWF) launched the Conservation Canine Programme in Tanzania.

The dogs, who are purchased from breeders in Europe, spend several weeks being taught to detect illegal wildlife products hidden in cargo or luggage.

The training begins with a Kong toy (affiliate link), which serves as a “neutral” odor, according to the AWF. Next, the dogs sniff small pieces of ivory.

“Positive reinforcement remains at the core of the program’s dog-training philosophy, with all training and handling done with the dogs’ physical and mental health in mind,” the AWF notes.

The dogs are then paired up with their handlers. The teams practice searching buildings, seaports and airports.

Will Powell, director of the Conservation Canine Programme, told CNN it was easier training the dogs than their handlers, because many of the handlers have never been around dogs.

“The first lessons are as basic as learning to call a dog across a room and be nice,” Powell said. “The dogs don’t get a paycheck, so handlers have to provide love and encouragement.”

The program’s first graduating class this year included eight dogs and 14 handlers from the Kenya Wildlife Service and Tanzania’s Wildlife Division. The teams will be deployed to areas identified as export or transit hubs for smuggled ivory.

The AWF is working with other wildlife authorities in Africa to potentially provide conservation canines throughout the continent.

“If dogs are used and intelligently placed, we are going to stop some of the routes the ivory comes through,” Powell told CNN. “The aim is to keep (poachers) on their toes.”

5 Cancers Dogs Can Sniff Out with Amazing Accuracy

A trained dog named Frankie is in the news for being able to sniff out thyroid cancer in urine samples. But Frankie is not alone — dogs have also been trained to use their extraordinary senses of smell to sniff out breast, lung, ovarian, prostate and other cancers. (Even untrained dogs have sniffed out their dog moms’ breast cancer and dog dad’s brain and skin cancers.)

During the training process, dogs are presented with urine or breath samples from patients with cancer, without cancer and with other diseases. A clicker is used when the dogs sniff cancer samples so they learn to target the odor of volatile organic compounds (VOCs) that are linked to cancer. The dogs are trained to signal the presence of VOCs by pawing, barking or sitting by the sample, and are rewarded when they do so.

Breast Cancer: 98 Percent Accuracy

In a 2003 study, trained dogs detected breast cancer in breath samples with 98 percent accuracy. The samples were collected by having volunteers blow into plastic tubes that were filled with polypropylene wool, which preserves the breath’s scent.

“The tubes actually collect molecules from inside the human body,” notes the InSitu Foundation, a non-profit organization in Malibu, Calif., that trains dogs to detect cancer. “The dogs are actually smelling the cells, gasses, vapors and many different volatile organic compounds.”

Even more amazing are the cases of untrained pet dogs who successfully sniffed out their dog moms’ breast cancer. There have been at least three reported cases over the past few years, all of them in the UK. In December 2014, Josie Conlan’s rescued Border Collie, Ted, began nuzzling a lump on her breast and crying, according to Gazette Live. The lump turned out to be cancerous. In April 2013 a Pug named Flo did the same thing for her dog mom, Marian Cooper. And in July 2012, the BBC reported that Penny, a Cavalier King Charles Spaniel, sniffed out Sharon Rawlinson’s breast cancer.

“A few anecdotal cases have suggested that dogs may sometimes be aware that their owner has cancer,” Martin Ledwick, with Cancer Research UK, told the BBC. “No reliable research has given a scientific explanation of how this could work.”

Lung Cancer: 71 Percent Accuracy

Trained dogs in a 2011 study, conducted by the Schillerhoehe Hospital in Germany, sniffed out lung cancer in breath samples with 71 percent accuracy, ScienceDaily reported. The samples were from lung cancer patients, chronic obstructive pulmonary disease (COPD) patients and healthy volunteers.

“In the breath of patients with lung cancer, there are likely to be different chemicals to normal breath samples and the dogs’ keen sense of smell can detect this difference at an early stage of the disease,” Thorsten Walles, author of the study, said in a press release.

“This is a big step forward in the diagnosis of lung cancer, but we still need to precisely identify the compounds observed in the exhaled breath of patients. It is unfortunate that dogs cannot communicate the biochemistry of the scent of cancer!”

Ovarian Cancer: 90 Percent Accuracy

A German Shepherd named Tsunami detected ovarian cancer in tissue samples with 90 percent accuracy during a 2014 study by the University of Pennsylvania.

Tsunami and two other dogs were trained using tissue samples from both cancerous ovaries and ovaries with benign disease, according to Bloomberg Business. Researchers are hoping sniffer dogs can someday be replaced with sensors that can detect cancerous tissue 1/100,000th the thickness of a sheet of paper.

“We don’t ever anticipate our dogs walking through a clinic,” Dr. Cindy Otto, founder and executive director of the University of Pennsylvania’s Working Dog Center, told the New York Times. “But we do hope that they will help refine chemical and nanosensing techniques for cancer detection.”

Prostate Cancer: 98 Percent Accuracy

Two specially trained dogs in a 2014 study were able to detect prostate cancer in urine samples with 98 percent accuracy, Medical News Today reported.

“These data show analysis of volatile organic compounds in urine is a promising approach to cancer detection,” said Dr. Brian Stork, a urologist from Grand Haven, Mich., who conducted a presentation of the findings at the annual American Urological Association conference.

“The possibility of using dogs to identify cancer is something most would never have considered possible a decade or two ago. It’s an interesting concept that ‘man’s best friend’ could help save your life.”

Thyroid Cancer: 88 Percent Accuracy

In a recent study by the University of Arkansas for Medical Sciences (UAMS), Frankie, a scent-trained, rescued German Shepherd mix, was able to sniff out thyroid cancer in 30 of 34 urine samples with 88 percent accuracy. He was just slightly less accurate than a standard thyroid biopsy — an invasive procedure using a needle.

“Current diagnostic procedures for thyroid cancer often yield uncertain results, leading to recurrent medical procedures and a large number of thyroid surgeries performed unnecessarily,” Donald Bodenner, M.D., Ph.D., said in a press release. “Scent-trained canines could be used by physicians to detect the presence of thyroid cancer at an early stage and to avoid surgery when unwarranted.”
