Dog sniffer dogs are incredibly skilled at detecting all sorts of things, but one of their most impressive abilities is detecting cancer.
These dogs can sniff out cancer with incredible accuracy, often detecting it before it's even visible on a scan.
In some cases, they can even detect the specific type of cancer, which is a huge advantage for doctors trying to develop a treatment plan.
Their keen sense of smell allows them to pick up on tiny changes in a person's body chemistry that indicate the presence of cancer.
Dogs in Detection
Dogs are incredibly skilled at detecting various substances, including contraband in containers, cancer in humans, and explosives. Their keen sense of smell allows them to pick up on subtle odor signatures that humans may miss.
Dogs can detect cancer in humans by sniffing skin, breath, urine, feces, and sweat. They can even detect certain types of cancer, such as melanoma, colorectal cancer, and lung cancer, with high accuracy.
Some breeds of dogs are better suited for detection work than others. While we don't know which breed has the best sense of smell, dogs have 20 to 40 times more odor receptors in their noses than humans do.
Dogs are used in various detection roles, including:
- Wildlife detection: Dogs help rangers catch poachers and detect illicit products derived from wild species.
- Cancer detection: Trained dogs can detect cancer in humans with high accuracy.
- Bomb detection: Dogs sniff out explosives and other threats in public places.
Their ability to detect these substances is due to their unique anatomy and training. With proper training, dogs can become invaluable assets in detection work, saving lives and preventing harm.

From Puppies to Protectors
Dogs in detection roles, like sniffing out contraband or explosives, undergo rigorous training to become top-notch protectors.
The training process for these dogs starts when they're between six and nine months old. During this initial phase, they're paired with personal handlers to build a strong bond. This bond is crucial for the dog's success in detection work.
Strategic exercises are used to reinforce this bond, teaching the recruits to handle challenging situations and respond to specific commands. The goal is to create a trusting partnership between the dog and handler.

In the second training phase, the dogs focus on learning skills related to detecting crimes against wild species or explosives. They learn to identify illicit products, apprehend poachers, or sniff out bombs.
The final stage of training sharpens the dogs' skills as they investigate crime scenes. They receive rewards for their good work, which helps motivate them to learn and perform their duties.
Dogs in detection roles can be trained to detect various types of cancer, including melanoma, colorectal cancer, lung cancer, ovarian cancer, prostate cancer, and breast cancer.
Here are some breeds commonly used for bomb-sniffing work:
- German shepherd
- Belgian shepherd (Malinois)
- Vizsla (Hungarian pointer)
- Labrador retriever
These breeds are prized for their good noses, calm demeanor in crowds, and love of play. Playing is essential for dogs in detection work, as they understand their job as a daily game of find-the-explosive.
Dogs in detection roles work in silence, relying on non-verbal cues like the leash to communicate with their handlers. They're trained to find explosives in various settings, from airports to public events.
When a dog retires from detection work, it's often due to illness or age. Military dogs typically retire at age 8 or 9, while TSA dogs can retire if they don't meet the agency's standards or fail remedial training.
Police Can't Prolong Traffic Stops
Police dog sniffs during lawful traffic stops are legal under the Fourth Amendment to the federal constitution. This means that as long as the traffic stop is legitimate, a police dog can be used to sniff for drugs.
An officer's mission during a traffic stop is limited to tasks like checking the driver's license, registration, and proof of insurance, and running a warrant check. These tasks can't be prolonged unnecessarily to conduct a dog sniff.
The detention must end once the tasks related to the traffic infraction are complete. If a dog sniff makes the stop take any longer than it otherwise would, it's considered an illegal extension of the detention.
The Supreme Court has ruled that an officer who doesn't have reasonable suspicion may not extend a traffic stop to conduct a dog sniff. This means that if an officer doesn't have a good reason to suspect criminal activity, they can't use a dog sniff as an excuse to prolong the detention.
Dogs in Cancer Research
Research has shown that trained dogs can detect many types of cancer, including melanoma, colorectal cancer, lung cancer, ovarian cancer, prostate cancer, and breast cancer.
Dogs are being used in cancer research and diagnosis, and their abilities may have significant benefits for humans. Using dogs to support the detection and diagnosis of cancer is a low-risk, noninvasive method.
Medical detection dogs present few side effects and may offer advantages because they are mobile, can begin work quickly, and can trace an odor to its source.
Dogs have been found to detect cancer in various bodily secretions, such as skin, breath, urine, feces, and sweat. They can even detect cancer markers in very low concentrations, as low as parts per trillion.
Some studies have shown that dogs can detect cancer with high accuracy, even for early-stage cancers. For example, one study found that a trained dog had a very high rate of accuracy in distinguishing between the breath of people with and without lung cancer.

Dogs may also help with developing machines that can reliably detect odor signatures from cancer, such as electronic noses. However, research is still underway and the effectiveness and reliability of canine cancer detection requires further investigation.
A study in 2021 reported that a dog trained to detect signs of breast cancer in urine was able to detect breast cancer with 100% accuracy among urine samples from 200 people. This study has yet to be repeated with a larger population of dogs to see if the outcomes can be reproduced.
Dogs may also detect other cancers, such as lung cancer and melanoma, even if they were not specifically trained to detect those cancers. This suggests there may be a common odor signature across different types of cancer.
Wild Species Defenders
In India, 94 sniffer dogs have been deployed across 19 provinces as part of the Super Sniffers programme.
These dogs have been highly successful in seizing wild species contraband from smugglers and catching poachers in the act.
The training programme began in India in 2008, initiated by TRAFFIC's India Office with support from WWF-India.
So far, these Super Sniffers have played a leading role in over 400 cases of crimes against wild species.
Dogs have an incredible sense of smell, capable of picking up even the tiniest traces of wild species in illicit products.
Sniffer dogs can detect various wild species parts and derivatives in trade, including those from tigers, elephants, and rhinos, deer meat, live birds, snakes, porcupines, red sanders, turtles, and tortoises.
Much like with detecting drugs or explosives, these dogs use their incredible sense of smell to detect these items.
These four-legged recruits are making a real impact in the ongoing efforts to combat crimes against wild species.
More sniffer dogs are being trained at three different centres to join the fight against wildlife crime.

Frequently Asked Questions
Do drug sniffer dogs actually work?
Yes, drug sniffer dogs can detect certain odours, including drugs, at extremely low concentrations. However, their results may not always be accurate, as they can produce false positives or negatives.
What is the best drug sniffing dog?
Labrador Retrievers, German Shepherds, and certain Terrier breeds are commonly used for narcotics detection in the US. These breeds are often selected for their keen sense of smell and strong work ethic.
What happens if you get caught by a sniffer dog?
If a sniffer dog indicates you, a police officer may ask you to be searched, which can involve a pat-down, removing clothing, or using a metal detector
How do dogs become sniffer dogs?
Dogs become sniffer dogs through a training process that associates a specific toy with the scent of controlled substances, allowing them to recognize and locate narcotics. This association is formed by exposing the dog to the scent of narcotics while presenting the toy, which the dog learns to associate with the odor.
What is a sniffer dog breed?
Sniffer dog breeds are trained canines that use their keen sense of smell to detect and locate specific items, including bombs, drugs, and missing people. Examples of sniffer dog breeds include Beagles, Bloodhounds, and Belgian Malinois.
