In a training facility, dog trainers train dogs to detect covid-19 positive people. To introduce the dogs to smell samples of COVID-19 positive people took an average of six months. Trainer says a dog can now tell the difference between infected and uninfected – or rather, by gestures when they detect COVID-19 positive people.
Sniffer dogs are increasingly being employed to track COVID-19 cases as a Turkish security company has joined with others worldwide to use K-9 dogs for this purpose. Although long-term studies on the abilities of sniffer dogs are not available, scientists believe that there may be some degree of accuracy in detecting positive cases.
How dogs detect covid-19
Odor detection dogs can accurately detect low concentrations with the help of volatile organic compounds.
“The potential impact of these pets and their ability to detect COVID-19 may be substantial,” Otto said in a statement.
The researchers will initially start the study with eight dogs to perform this precise identification task.
Over three weeks, the dogs would be exposed to COVID-19 positive saliva and urine samples in a laboratory setting, which would be done through an odor-printing process, he said.
Once dogs have learned to smell, researchers can set the stage for a test to determine this. Can dogs identify people infected with COVID-19?

Scientists trained dogs to detect COVID-19 smell in humans.
According to an American training that, the COVID-19 program Will use odor detection dogs to discriminate between positive and negative patient samples
Scientists in the United States of America say they are training dogs to detect COVID-19 in humans by smelling the disease in saliva and urine samples.
According to researchers from the University of Pennsylvania’s School of Veterinary Medicine (Penn Vet) in the US, the training program will use odor detection dogs to discriminate between samples from COVID-19 positive and COVID-19 negative patients.
With 300 million odor receptors — compared to six million in humans — dogs are uniquely positioned to help detect disease, he said in a statement.
The study – which will explore the sensitivity and specificity of odors – sets the stage for a pooch to be a force multiplier in the mission of detecting COVID-19, particularly in asymptomatic patients or in hospitals or businesses environments where testing is the most challenging, according to the researchers.
How sniffer dogs are learning to smell the coronavirus
Research dogs are part of the group that can smell the distinctive odor of SARS-CoV-2, the virus that causes COVID-19.
As the disease spread worldwide, scientists deployed tools such as the polymerase chain reaction test. A team of pet researchers from the School of Veterinary Medicine at the University of Pennsylvania set out to determine this. Can dogs also be trained to detect infection?
The proof-of-concept study, published in April in PLOS ONE, reveals the findings. That virus has an odor that trained dogs can detect in urine and saliva. Now, the researchers—with the help of Tuca, Grizz, Toby, Rico, and Roxy—are investigating. Can dogs smell the coronavirus in sweaty t-shirts?
Suppose dogs can accurately detect it on clothing. So they can patrol places like airports and stadiums to smell the virus in public settings.
The smell of sweat for dogs to detect covid-19
Dog’s sense of smell is thought to be 1,000 to 10,000 times better than ours. They can sniff out early signs of Parkinson’s diabetes, disease, several types of cancer, impending epileptic seizures, malaria, and other conditions. Dogs assist search and rescue teams in the wake of natural disasters. And work as an ally in military missions while sniffing out hidden explosives.
Dogs trained to detect the COVID-19 virus in sweat can walk in lines of people. And can smell the infection right away.
Researchers don sweaty T-shirts and a series of distractions. – Clean cloth, shipping material, or rubbing alcohol on the ends of the eight-spoke metal wheel inside all mesh canisters. Only one canister will contain a T-shirt to be worn by that person.
Who had tested positive for COVID-19 within 48 hours of wearing it? Dogs know how to spin the wheel until they detect that positive sample.
Plans to be employed at airports and similar locations
Once the training program is completed, the company plans to employ them at airports and similar locations. On Wednesday, the company’s manager, Turg Ahan, told Anadolu Agency (AA) that he set up his dog train facility in 2019 and decided to train them for coronavirus detection after the pandemic hit the world.
Dogs to detect covid-19 in other places
Doggy detection work cannot be compared with polymerase chain reaction (PCR) and other tests used to diagnose COVID-19 accurately. But they can help in detecting suspected cases in crowded places. He said he ran a study with four stages and found that dogs had a 94% success rate seeing positive patients.
Orkun Kara, a pet trainer at the facility, said he worked with ten dogs. And they all were successful “to varying degrees” in sniffing out positive cases. Kara explained. That dog can already distinguish eight different smells emanating from explosives, and it will only be “the ninth smell.”
Dogs to detect covid-19 Final thought
In an April study with urine and saliva samples, Otto says that dogs detected the virus with 96 percent accuracy. The current study using sweat-wicking T-shirts is underway, but dogs have been remarkably successful at that, she says.
