What You'll Learn
Dogs can detect explosives
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. This advanced olfactory sense, combined with rigorous training, makes them invaluable for security at airports, borders, schools, and public events.
Dogs are trained to detect explosives and firearms threats. ATF-certified explosives detection canines are exposed to five basic explosives groups, including chemical compounds used in an estimated 19,000 explosives formulas. This exposure to various explosives from the basic explosive families gives the dogs the ability to detect a wide range of commercial or improvised explosives.
Bomb detection dogs work with TSA and local police forces at airports to monitor security checkpoints and screen checked baggage for signs of explosives. These dogs can detect the volatile chemical substances used in bomb production, which are usually undetectable by the human nose. Even if someone tries to disguise the smell of explosives, a dog's nose contains over 100 million scent receptors, making it impossible to mask the chemicals that compose them.
The ATF explosives detection canine program trains dogs to detect explosives, explosives residue, and post-blast evidence. These dogs can also detect smokeless powder and other explosive fillers, making them capable of finding firearms and ammunition hidden in containers and vehicles, on persons, or buried underground.
The ATF's 10-week explosive detection training program conditions dogs to identify explosives and their residue. This training methodology allows for repeated exposure to various explosives odors daily, reinforcing these scents to the dogs. To earn ATF certification, dogs must pass a blind test where they must successfully detect 20 different explosive odors, including two they were not exposed to during training.

They can smell drugs
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 various factors such as wind conditions, the concentration of the odour, and the dog's training and experience. This advanced olfactory sense, coupled with their training, allows them to assist in combating drug trafficking, prescription medication abuse, and other illicit activities, making them invaluable assets in various settings, including airports.
Drug-sniffing dogs are commonly used in airports to detect illegal substances. They work in conjunction with their handlers, walking through security checkpoints and sniffing the air around passengers and their luggage. Their noses contain over 100 million scent receptors, making it nearly impossible to mask certain scents. For example, drug dogs can detect the scent of marijuana, even after it has been smoked and only residual amounts remain on clothing. They can also smell marijuana in its various other forms, including dried flowers, oils, infused products, and edibles.
In addition to marijuana, drug dogs can detect a wide range of other drugs and narcotics, including cocaine, heroin, crystal meth, MDMA (ecstasy or molly), and opioids such as fentanyl. They can even detect prescription medications like codeine, morphine, and oxymorphone, although police dogs are typically only trained to detect opioids that are illegal in all circumstances. The versatility of detection dogs makes them essential in law enforcement efforts to combat drug-related crimes and protect public safety.
While drug-sniffing dogs are highly effective, it is important to note that their accuracy can be influenced by factors such as their training, the working conditions, and the specific substance they are trying to detect. Additionally, the use of drug dogs can raise legal and privacy concerns, particularly regarding unreasonable searches and seizures. Nonetheless, their advanced olfactory senses and speed at which they can work make them crucial members of airport security teams, helping to intercept illegal substances and enhance security measures.

Firearms are detectable
While drug-sniffing dogs are the most commonly recognised form of canine security assistance, dogs can also be trained to detect firearms. Firearms dogs are often used in combination with their drug detection duties. They can detect the scent of gunpowder, which lingers on a gun for weeks after it has been fired.
The dogs work with their handlers to screen checked baggage and passengers for firearms, in a similar manner to how they find explosives and drugs. They walk through security checkpoints, sniffing the air around passengers and their luggage.
The dogs' keen sense of smell can detect all sorts of dangerous substances, including bombs and drugs, as well as contraband that doesn't pose an immediate security threat, such as certain organic goods. Their advanced olfactory senses, with over 100 million scent receptors, make them invaluable for security at airports, borders, schools, and public events.
In addition to their security benefits, firearm-detecting dogs also offer social and emotional advantages for the community. In schools, they can deter gun violence and mass shootings, while also bringing students joy and helping them feel more comfortable.

Dogs can sniff out Covid-19
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 odor, and the dog’s training and experience. This advanced olfactory sense has been leveraged in various fields, including law enforcement, security, and medicine.
One innovative application of canine scent detection is in the identification of COVID-19. Research has shown that dogs can be trained to recognize unique volatile organic compounds, called "biomarkers," in the exhaled breath of individuals with COVID-19. These biomarkers are specific to the virus and allow dogs to accurately detect COVID-19-positive individuals. In a study conducted by Florida International University, four dogs, including a Terrier mix named Mac and a Belgian Malinois named Cobra, underwent training using a scent detection wheel with COVID-19 positive and negative masks. The dogs achieved remarkable accuracy, with Mac identifying COVID-19 positive masks correctly 96.2% of the time and Cobra reaching an impressive 99.4% accuracy rate.
The success of these trained dogs in detecting COVID-19 has led to their deployment in various settings, including airports and public events. For example, Cobra, the Belgian Malinois, was utilized to screen guests prior to the Food and Wine Festival in Miami in May 2021. Additionally, the Bristol County Sheriff's Office in Massachusetts employed two young Labradors, Duke and Huntah, to detect COVID-19 in their facilities and local schools.
The use of dogs as COVID-19 sensors offers a rapid and efficient screening method that complements other testing approaches. Their keen sense of smell and ability to detect specific biomarkers make them a valuable tool in helping to stop the spread of the virus and controlling the pandemic. However, it is important to note that the idea is not without its limitations and challenges. Virologists have pointed out that COVID-19 infects similar cells as other viruses, which may produce overlapping scents that dogs detect. Further research is needed to determine if dogs can distinguish between different virus types and their respective compounds.
