Are Airport Dogs Always Drug Sniffing Dogs?

Dogs are a common sight at airports, and they are often used to improve safety and security. While drug-sniffing dogs are prevalent in airports, they are more commonly used to detect explosives and prevent dangerous events. Dogs have an incredible sense of smell, with 20-40 times more odour receptors in their noses than humans, making them effective at identifying threats. They work in silence, walking through security checkpoints and sniffing passengers and their luggage for drugs, explosives, and other contraband items. Their efficiency and passive role mean that most passengers are unaffected by their presence.

Drug dogs are more common on international flights

Dogs are a common sight at airports nowadays, and they are used for a variety of tasks, including drug and explosives detection, and assisting travellers with disabilities. The US Transportation Security Administration (TSA) has been training dogs for security purposes since 1974, when a German Shepherd identified a bomb at New York's JFK Airport.

Drug-detecting dogs, often referred to as drug dogs, are trained to recognise a wide range of narcotics, including marijuana, opium, cocaine, and heroin. They work in tandem with a handler, silently walking through security checkpoints and sniffing passengers and their luggage. When a suspect is identified, the dog gives a silent cue, such as sitting down next to the suspect's bag. Drug dogs work quickly and efficiently, ensuring most passengers are unaffected by their presence.

While drug dogs can be found in airports across the globe, they may be more prevalent on international flights due to the higher security risks associated with cross-border travel. International flights often involve stricter security measures, and the presence of drug dogs can provide an additional layer of protection against drug smuggling and illegal activities.

The use of drug dogs on international flights allows for the detection of drugs that may have been recently consumed or handled by passengers. Even if an individual is not carrying drugs, traces of narcotics can remain on their belongings or clothing. Drug dogs are capable of identifying these traces, potentially leading to further investigation by authorities. This serves as a deterrent for drug-related crimes and helps maintain a safe environment for travellers.

Additionally, international flights often involve longer travel distances, which may increase the likelihood of drug-related incidents. The longer duration of the flight can provide more opportunities for drug consumption or distribution. As a result, drug dogs can play a crucial role in preventing drug-related activities during these longer journeys.

In conclusion, drug dogs are an important component of airport security, and their presence is particularly notable on international flights. Their advanced sense of smell, combined with efficient screening capabilities, ensures a safer travel experience for passengers. While drug dogs may not be the only line of defence against drug-related incidents, they certainly contribute to a comprehensive security strategy at airports worldwide.

Dogs can detect explosives

Dogs are widely recognised as one of the best tools for detecting explosives. Their olfactory sense is incredibly advanced, with a sense of smell a million times more sensitive than a human's. This makes them an invaluable asset in airports, where they can screen passengers and their luggage for explosives.

Dogs can be trained to detect a wide range of scents, including explosives and the volatile chemical substances used in bomb production. These chemicals are often undetectable by humans but are easy for dogs to find. Their noses contain over 100 million scent receptors, making it impossible to mask the chemicals that compose explosives.

The Transportation Security Administration (TSA) in the United States first implemented canines into its cargo screening protocols in 2008. This came in response to the need for enhanced security measures following the September 11th terrorist attacks and other subsequent attacks.

The ATF (Bureau of Alcohol, Tobacco, Firearms and Explosives) also utilises explosives detection canines. These dogs undergo a 10-week explosive detection training program where they are conditioned to detect explosives, explosives residue, and post-blast evidence. ATF-trained dogs can also detect firearms and ammunition hidden in various places, including containers, vehicles, and on persons.

The science behind canine explosives detection is based on odour recognition through food and praise reward conditioning. This training method allows dogs to be repeatedly exposed to various explosive odours, reinforcing these scents in their memory. To earn ATF certification, dogs must pass a blind test where they successfully detect 20 different explosive odours, including two they have never encountered before.

Dogs can sniff out illnesses

Dogs are well-known for their incredible sense of smell, which has been utilised by police forces and security services for decades. With around 220 million scent receptors compared to our measly 5 million, dogs can detect certain odours in parts per trillion and notice subtle changes in scent. This ability has been used to detect bombs, drugs, and firearms. However, dogs are now also being used to sniff out human illnesses.

Cancer Detection

Dogs have been shown to be able to detect various types of cancer, including breast, lung, ovarian, prostate, and colorectal cancers. In a 2021 study, a trained dog was able to identify urine samples from people with breast cancer with 100% accuracy. Another study in 2019 found that dogs could correctly identify blood samples from cancer patients with 97% accuracy. Even untrained dogs have been known to detect cancerous lesions on their owners, alerting them to get checked by a doctor.

Diabetes Alert Dogs

Diabetic Alert Dogs (DADs) are service dogs trained to alert their owners to high or low blood sugar levels, which can be life-threatening. A 2016 study found that dogs can detect the VOC isoprene, which is released in higher amounts when blood sugar drops. A 2019 study showed that, on average, 81% of alerts by DADs occurred when sugar levels were too high or too low.

Narcolepsy

Narcolepsy is a neurological disorder that affects the brain's ability to regulate sleep-wake cycles, causing people to suddenly fall asleep. A 2013 study found that trained dogs were able to detect 11 out of 12 narcolepsy patients by scent alone. These dogs can provide a warning up to five minutes before an attack, allowing the person to get to a safe place and avoid potential injury.

Migraines

While much of the evidence is anecdotal, a 2013 survey found that 54% of migraine sufferers who owned dogs noticed a change in their dog's behaviour before or during a migraine attack. The dogs displayed increased attentiveness, deliberate pawing, and sitting or lying on or near the owner.

COVID-19

During the COVID-19 pandemic, a trial found that dogs were able to correctly identify clothing items that had traces of COVID-19 94% of the time. This ability could be used to quickly and efficiently screen large numbers of people, although other testing methods are currently more accurate.

The use of dogs to detect illnesses is a developing field, and researchers are still working to understand how dogs are able to do this and how they can be best utilised in healthcare settings.

Dogs can detect counterfeit money

Dogs are commonly used at airports to detect drugs, explosives, firearms, and even diseases like Covid-19. Their advanced sense of smell, which is said to be thousands of times better than humans', makes them an invaluable asset in ensuring the safety of passengers and staff.

However, dogs at airports are not limited to drug and explosive detection. They are also trained to sniff out cash, specifically counterfeit money. Labradors, known for their personable natures and strong prey drive, are often the breed of choice for this task. These dogs are trained to detect the unique scent of the ink used on banknotes. They can also differentiate between various currencies, which is crucial in an airport setting where international travellers converge.

The process of training a dog to detect counterfeit money is intricate. Dogs are chosen for their enthusiastic scent drive and then taught to locate the cash. The training is reward-based, with the dog receiving a toy or a rolled-up white towel when they successfully detect the money. Over time, the reward is only given when the dog accurately identifies the scent of the ink on the banknotes.

These currency detection dogs work in tandem with their handlers, silently alerting them to the presence of suspicious items. The dogs may use a variety of signals, such as staring at or digging at the spot, or placing their paw on the suspicious item. Their keen sense of smell, coupled with their training, makes them adept at uncovering hidden cash, whether concealed in baggage, cargo, packages, or on a person's body.

The presence of these cash-sniffing canines at airports acts as a deterrent to criminal activity, helping to curb money laundering, tax evasion, and the circulation of illicit funds. They are an integral part of the security apparatus, working swiftly and efficiently to ensure the safety and security of all airport users.

Dogs can detect illegal animals

Dogs are a common sight at airports, where they assist security teams in detecting illegal substances. These detection dogs are trained to use their senses to identify a wide range of substances, including illegal drugs, explosives, and even certain types of animals.

Detection dogs are highly effective in identifying endangered animal species, such as the black-footed ferret. They can also detect wildlife scat, which is valuable for research and wildlife conservation efforts. This process, known as wildlife scat detection, allows for the non-invasive study of various species, including the collection of data from their feces.

The use of detection dogs to identify illegal animals is particularly relevant in combating the illegal trade of pets, which has significant economic and health implications. The European Union (EU) has conducted enforcement actions to address this issue, uncovering fraudulent activities and illegal transportation of animals across borders. Detection dogs play a crucial role in these investigations, helping to identify irregularities and falsified documentation associated with the illegal trade.

In addition to their work at airports, detection dogs are also employed by police forces and other law enforcement agencies to locate illegal animals and other contraband. Their advanced sense of smell enables them to discern individual scents, even when masked by other odors. This capability proves invaluable in foiling attempts to smuggle illegal animals or substances.

Overall, detection dogs are a valuable asset in maintaining security and combating illegal activities, including the detection of illegal animals at airports and other transportation hubs. Their keen sense of smell and training make them indispensable partners in ensuring compliance with regulations and protecting endangered species.
