One day in late June, a forest patrol deep in the jungles of Central India came across a distressing sight. Twelve spotted deer and two sambar deer lay dead around a poisoned pond. This was among the biggest cases of suspected mass poisoning of wild herbivores ever reported in the region. But without witnesses, CCTV footage or any other clues, the foresters were stymied.
Help arrived in the form of an unlikely but scrappy detective: a Belgian Malinois dog with a highly trained nose. She found the footprints of the poachers, picked up a scent and led the officials out of the forest, through fields and into a house in a village. There, they discovered fresh meat, bloodstains, animal hair, snares and other hunting equipment, and they took three suspects in for questioning. They also stationed a guard at the crime scene to ensure that other thirsty animals did not meet the same fate.
It is rare for wildlife crimes to be resolved this quickly. Around the world, efforts to combat wildlife trafficking are often undermined by limited institutional capacity: too few trained personnel, too little investigative expertise and scarce resources. Training people to locate and identify trafficked animal products is particularly difficult, says Belinda Wright, founder of the Wildlife Protection Society of India (WPSI), which has trained more than 8,000 forest, police and customs officers since 1994. “In the ’60s and ’70s, forest guards traveled the jungle on foot, and Indigenous communities like the Baiga could tell whether tracks belonged to animals, local people or outsiders,” she says. “Those skills are disappearing.”
This is where super sniffers come in. “Sniffer dogs are emerging as the secret weapon of Indian wildlife authorities,” says Nitin Desai, director (Central India) at WPSI. “When there are no eyewitnesses, dogs find evidence that no human eye can detect.” He recalls a case in which an informant reported that a villager had killed a wild boar. Forest officials searched the suspect’s house but found nothing. Only when a sniffer dog arrived did investigators discover tiny bones near the washing area. From there, the dog tracked the scent all the way to the kill site.
Since 2008, WWF-India (the World Wide Fund for Nature-India) has trained more than 120 wildlife sniffer dog squads, each comprising a dog and two handlers. Deployed across 22 states, they assist forest departments in detecting poaching and wildlife trafficking, helping seize tiger skins, pangolin scales, ivory and live animals while also deterring poachers in vulnerable landscapes.
It is a scorching summer afternoon in Tadoba-Andhari Tiger Reserve in the central Indian state of Madhya Pradesh, with temperatures above 110° Fahrenheit. Under a silk cotton tree, 24-year-old forest department handler Saurabh Nikhat puts Maya, a Belgian Malinois, through her paces. Maya has become one of the reserve’s most valuable investigators, helping track wildlife contraband to suspected traffickers.
Nikhat had never worked with dogs before meeting Maya when she was four months old. “We didn’t get off to a great start,” he laughs. “She bit me, and I had to take anti-rabies shots.”
WWF-India trains young German shepherd and Belgian Malinois puppies, usually starting at between three and six months old, in collaboration with government canine training centers. Each dog is paired with two handlers and undergoes seven to nine months of training, first in obedience to build trust and then in detecting wildlife contraband such as tiger and leopard skins and bones, elephant ivory, bear bile, deer antlers, red sandalwood and caterpillar fungus.
The work does not end there. To stay effective, Maya follows a strict daily routine of exercise and scent practice prescribed by WWF-India. “The fresher the scent and the less disturbed the crime scene, the better she performs,” Nikhat says. According to Dipankar Ghose, senior director for biodiversity conservation at WWF-India, heavy rain, strong winds, extreme temperatures, dense vegetation and excessive human movement can all interfere with scent trails. Dogs are therefore trained to work under difficult field conditions through repeated exposure to varied terrain and real-life scenarios.

That preparation has paid off. Nikhat recalls investigating the death of a young tiger found in a stream. Water usually destroys scent trails, yet Maya led investigators to the man who had dragged the carcass from the water.
“Today, it would be very difficult for us to curb wildlife poaching without sniffer dogs,” says Prabhu Nath Shukla, field director of Tadoba-Andhari Tiger Reserve. The biggest constraint, he adds, is the need for two dedicated handlers for each dog, which makes the program expensive for state forest departments to expand.
Dogs are being deployed in the fight against wildlife trafficking the world over, not just in India. In South Africa’s Kruger National Park, canine units track rhino poachers and detect concealed firearms and rhino horn. In Kenya and Tanzania, dogs help intercept ivory and bushmeat traffickers at ports and airports. In Australia and the United States, they locate invasive species, endangered wildlife, scat samples and diseased trees.
Research shows that dogs don’t simply have a better sense of smell than humans; their entire respiratory system is optimized for odor detection. Humans have around five million olfactory receptors; dogs have roughly 200 million. The part of their brain devoted to smell is proportionately about 40 times larger than ours, and their noses separate inhaled air into streams for breathing and scent analysis, allowing them to detect odors at astonishingly low concentrations.
Their biology makes them “an extraordinary force multiplier for conservation,” says Ghose. Dogs can detect concealed wildlife products, recover hidden evidence, track suspects across difficult terrain and search large areas far faster than people alone. A global review of more than 600 comparative conservation studies found that wildlife detection dogs outperformed alternative survey methods nearly 89 percent of the time. Similarly, a study on narcotics dogs found positive detection rates above 90 percent and false alert rates below 10 percent. A 2024 review found that wildlife sniffer dogs are generally able to search larger areas, locate more suspicious wildlife products and work faster than humans. While the review cautions that there is little standardization of performance metrics in sniffer dog project evaluations, in the field, Nikhat says that in his experience, false alert rates are low, and wildlife dogs have been able to sniff out contraband that humans would have been hard pressed to identify.
At Kanha Tiger Reserve, a dog named Daisy has solved five wildlife crime cases in under two years, tracking poachers from kill sites to their homes and uncovering hidden poison, hunting nets and venison. In February 2026 in Telangana’s Kawal Tiger Reserve, when the forest department found illegally felled teak trees, super sniffer Hunter tracked the scent from the crime scene over a distance of more than 5 kilometers to a house in a nearby village, where officials identified and apprehended the alleged offender. In Madhya Pradesh’s Satna Forest Division, German shepherd Nirman has assisted in more than seven tiger investigations, earning national recognition for protecting one of India’s most endangered species.
Beyond solving crimes, the dogs’ presence also deters them. Shukla notes that when Nikhat and Maya patrol village fairs near Tadoba, local butchers think twice before attempting to sell poached meat. The dogs become valued members of the forest department, forging lifelong bonds with their handlers and colleagues. When Rana, the celebrated sniffer dog who helped solve more than 53 wildlife trafficking cases in Karnataka, died in 2022, the state forest department honored him with a full funeral — a tribute usually reserved for officers who have served with distinction.
Back in Tadoba, we pass several small shrines with idols of the tiger god locally known as Waghoba. Many have been built at spots where tigers have attacked residents of neighboring villages. The little yellow and black striped idols highlight the fact that protecting wildlife ultimately requires more than better policing and super sniffers. Recent research from Tadoba shows a dire need for better policies that help people live safely and fairly alongside wildlife.
Meanwhile, a new batch of eight young dogs and 16 handlers is being trained in Panchkula, Haryana. “It’s good news for conservation,” Nikhat says as he gets ready to take Maya back to their quarters. “Not such good news for the criminals, though!”
