Dogs are employed at airports to detect a wide range of substances and objects, from narcotics to explosives and firearms. Their advanced olfactory senses allow them to detect scents from considerable distances, making them invaluable assets in enhancing airport security. While drug-sniffing dogs can detect various illegal substances, such as cocaine, heroin, and marijuana, their primary focus at airports is the detection of explosives and firearms. The detection of narcotics may be less common, and the presence of drug-sniffing dogs at airports may be more of a misconception than a regular occurrence. However, their ability to detect a range of substances, including MDMA, makes them crucial in law enforcement and security beyond the airport setting.

What You'll Learn
Drug-sniffing dogs can detect Molly/MDMA
Drug-sniffing dogs are commonly used in airports, concerts, and other large spaces with security personnel. They are trained to detect a wide range of scents, including narcotics, explosives, and even firearms. Their advanced olfactory senses allow them to detect a wide array of substances, making them invaluable assets in enhancing security measures.
While drug-sniffing dogs can detect various illegal substances, it is important to note that their accuracy can be influenced by several factors, including their training, working conditions, and the specific substance they are trained to detect. For example, marijuana, despite its legalization in some states, is one of the most commonly detected substances due to its distinct odour.
Drug-sniffing dogs are capable of detecting MDMA, also known as ecstasy or Molly. These dogs are frequently used at music festivals and parties to find this synthetic drug, which is popular among young adults. Their ability to detect MDMA makes them valuable in law enforcement's efforts to combat illicit drug use and enhance public safety.
However, the presence of drug-sniffing dogs in airports has been a subject of debate. In the United States, drug-sniffing dogs are not commonly used in the passenger-facing side of airports. Instead, they are often utilised in international arrivals and departures, specifically in customs, to detect explosives and firearms. While drugs are also a concern, the detection of explosives and firearms takes precedence due to their potential impact on airport security.
The use of drug-sniffing dogs in airports varies across different countries and jurisdictions. In some cases, drug-sniffing dogs may be present to detect a wider range of substances, including MDMA. However, the primary focus of airport security remains the detection of explosives and other immediate security threats.

Airport dogs are more likely to be bomb-sniffers
While drug-sniffing dogs are highly effective at detecting illegal substances, airport dogs are more likely to be bomb-sniffers. In fact, credible reports indicate that "drug sniffer dogs" are not commonly used in the passenger-facing side of US airports anymore. Even if a drug dog at an airport could smell the vape cart in your carry-on luggage, it probably wouldn't be trained to respond. Instead, they are there to smell for bombs.
Dogs have an incredible sense of smell, allowing them to detect scents from considerable distances. On average, dogs can smell scents from up to 12 miles away, depending on factors such as wind conditions, the concentration of the odour, and the dog's training and experience. This advanced olfactory sense allows them to detect a wide array of substances. Their training allows them to assist in combating drug trafficking, prescription medication abuse, and other illicit activities, such as smuggling and terrorism, making them invaluable assets in various settings.
The use of explosive detection dogs, along with advanced screening technology, has played a pivotal role in enhancing security measures at airports. These highly skilled dogs, combined with the latest screening techniques, have become an integral part of airport security. The Explosives Detection Canine Team Program, managed by the Transportation Security Administration (TSA), has been a symbol of canine excellence for over 30 years. The program now operates within the TSA's Aviation Operations Law Enforcement Division. Explosive detection canine teams have proven to be highly effective due to their exceptional mobility and reliable detection rates.
Bomb-sniffing dogs are also dual-trained to identify various explosives, making them invaluable for security at airports, borders, and public events. Their versatility makes them an essential part of law enforcement efforts to protect the public.

Dogs can smell through luggage
Dogs have an incredible sense of smell, with nearly 300 million olfactory receptors in their noses, compared to humans' measly five million. They can detect scents from up to 12 miles away, and their accuracy in detecting drugs can be influenced by factors such as their training, the conditions they work in, and the substance they are trained to detect.
Drug-sniffing dogs are commonly used in law enforcement and security at airports, borders, schools, and public events. They are trained to detect a wide array of substances, including illegal drugs such as marijuana, cocaine, heroin, and MDMA. However, it is important to note that they are not commonly used on the passenger side of airports, and if they are, they are likely trained to smell explosives, not drugs.
Dogs cannot smell through airtight containers made of metal or glass, as these materials are non-porous and prevent any odours from escaping. However, they can smell through plastic containers, as plastic is porous and odours will eventually seep through the material, allowing dogs to catch a scent.
While drug-sniffing dogs are highly effective, their reliability has been questioned. For example, in a controlled experiment, a drug dog was unable to detect the scent of marijuana, cocaine, methamphetamine, or heroin stored in odor-proof bags. However, in real-world scenarios, drug dogs have been known to respond to the odour of narcotics even when they are in heat-sealed or odour-sealed bags. This discrepancy may be due to the bags not being truly odour-proof or to the dog responding to residual odours on the outside of the container.
Overall, while drug-sniffing dogs may not be able to smell through all types of luggage, their advanced olfactory senses and training make them valuable tools in law enforcement and security, including at airports.

Dogs can detect COVID-19
While drug-sniffing dogs are commonly used in law enforcement and security, they are not often used in the passenger sections of airports. These dogs are typically used to detect illegal substances, combat drug trafficking, and enhance security measures at borders, schools, and public events.
However, the COVID-19 pandemic has highlighted another potential use for these canines: detecting infectious diseases. Dogs have an incredibly sensitive sense of smell, with 1,094 olfactory receptors compared to humans' 802. This superior olfactory ability allows them to distinguish between different diseases and metabolic disorders by detecting volatile organic compounds (VOCs) or "olfactory fingerprints."
Numerous studies have been conducted to test the ability of dogs to detect COVID-19, and the results are promising. A meta-study published in the Journal of Osteopathic Medicine included 29 studies with over 31,000 samples, and it concluded that dogs could detect COVID-19 as well as or even better than RT-PCR and antigen tests. The dogs were able to identify asymptomatic individuals, those with long COVID, and new COVID variants.
Another study conducted by UC Davis alumna Jenna Gadberry in partnership with the University of Pennsylvania's Penn Vet Working Dog Center also showed promising results. The dogs were trained to detect the unique odors and metabolites associated with COVID-19, and they successfully identified the virus in clinical samples of saliva and urine. The second phase of the study explored non-invasive methods, focusing on sweat samples. The overall sensitivity of the dogs in this study was 81.9%, with a specificity of 90.8% and a false-positive rate of 9.2%.
These studies demonstrate that dogs can be powerful tools in COVID-19 detection and could be used to provide quick, non-intrusive, and accurate results in public settings, helping to reduce the spread of the virus.

Dogs can smell guns and ammunition
While drug-sniffing dogs are commonly used in law enforcement, sniffer dogs at airports are typically trained to smell for bombs. They are trained to detect various explosives, making them invaluable for security at airports, borders, and public events.
Dogs can also be trained to detect the scent of weapons and ammunition. These firearm-sniffing dogs are becoming more and more popular to help police officers and law enforcement keep places such as airports, concerts, and schools safe. They are trained to sniff out and sense firearms and then alert their handlers to the location or the person who has them.
These dogs are trained to smell gunpowder and the residue it creates. Even if there is only a single bullet in a gun that has never been fired, a dog will be able to identify this scent. The scent of gunpowder is at its strongest two to three hours after a firearm has been discharged, so firearm-sniffing dogs ideally need to be on the scene within this time frame. They are also trained to sniff out guns that have not been used or touched for several months.
The use of firearm-sniffing dogs provides benefits such as lessening the issues surrounding a coercive environment as consent must be freely and voluntarily given. In addition, a gun dog handler does not have to worry about human scent contamination of the area to be searched.
