Once upon a time in the picturesque village of Düzpelit, nestled in the snow-covered landscapes of Ordu, Turkey, a dedicated veterinarian named Ogün Öztürk found himself on a unique mission. He had been summoned to the village to attend to a sick cow, a task he expected to complete swiftly and return home. Little did he know that this visit would lead to an unexpected and heartwarming connection.
As Ogün wrapped up his work with the ailing cow, he noticed something out of the ordinary. Through the thick blankets of snow, he spotted a determined little girl trudging towards him, carrying a pup on her back. Their extraordinary friendship began at that very moment.
The courageous girl was none other than Cemre Su Türköz, a resident of the village. Her faithful companion, Pamuk, had been suffering from an incessant itch for several days. Worried about her furry friend’s health, Cemre was determined to find a veterinarian as soon as possible. However, heavy snowfall had cut off access to the district center, leaving her with no choice but to explore alternative options. As luck would have it, an opportunity presented itself.
That fateful day, Cemre heard that a veterinarian would be in town to tend to a cow. Fearing that the vet might leave the village before she could seek his help, Cemre Su placed Pamuk on her back and embarked on a journey of over a mile along treacherous snow-covered mountain roads to reach Ogün’s location. Her arrival took the vet completely by surprise.
The resolute young girl approached Ogün and explained her predicament – her dog’s persistent itch, the inability to reach the district center due to the snow, and her desperation to have Pamuk examined. Who could refuse such an astonishing and determined client? Without hesitation, Ogün conducted a thorough examination, and fortunately, Pamuk’s condition was not dire. A simple topical medication would suffice to alleviate his discomfort.
In awe of the 8-year-old’s courage, Ogün refused to accept any payment for his services. Cemre offered approximately 7 liras, but he kindly declined. The kindness and bravery displayed by Cemre were rewards beyond measure for the compassionate vet.
This encounter marked the beginning of a beautiful friendship. Ogün continued to visit the village, not only to check on Pamuk’s well-being but also to spend time with Cemre and her beloved dog. Through the harshest of weather conditions, Pamuk felt the love and care that the little girl had showered upon him. It was a heartwarming tale of friendship and the boundless love between a little girl and her loyal canine companion.
Can dogs really detect Covid-19 infections faster and more accurately than a lateral flow test?
Results indicated that not only can dogs detect Covid faster, but they can also do so in a non-intrusive manner – so no need to swab your throat or nose
Dogs can detect Covid-19 faster and more accurately than a PCR test, a new study shows.
Researchers looked at the ability of canines to recognise the virus and its variants, even when they are obscured by other viruses, like those from common colds and flu.
More than 400 scientists from over 30 countries contributed to the study as well as 147 scent dogs, according to the findings published in the Journal of Osteopathic Medicine.
After analysing many studies covering both field and clinical experiments, Professor Dickey and Junqueira found that dogs who are trained to sniff out scents are “as effective and often more effective” than antigen tests.
A total of 53 dogs were trained to sniff out Covid scents, while 37 were not and scientists found that the dogs that were not trained were in some cases “slightly superior” to those that were pre-trained.
“The previously untrained dogs have the advantage that they are not as prone to indicating on scents other than the Covid–19 associated scent,” the paper said.
The results indicated that not only can dogs detect Covid faster, but they can also do so in a non-intrusive manner. This means you won’t need to put a swab in your throat or nose.
How can dogs detect the virus?
This essentially comes down to the dog’s highly evolved nose with its ability to sense out smells quicker.
Dogs possess up to 300 million olfactory receptors in their noses, compared to about six million in humans. And the part of a dog’s brain that is devoted to analysing smells is about “40 times greater” than humans. Canines also have ‘neophilia’, which means they are attracted to new and interesting odours
And so, with all these enhancements, dogs can detect very low concentrations of odours associated with Covid infections.
“They can detect the equivalent of one drop of an odorous substance in 10.5 Olympic-sized swimming pools,” Professor Dickey said. “For perspective, this is about three orders of magnitude better than with scientific instrumentation.”
Scientists also found that in some cases, the animals were also able to detect the virus in pre-symptomatic and asymptomatic patients, “whose viral load was too low for conventional tests to work.”
Professor Dickey has said that dogs can also differentiate Covid and its different variants in the presence of other respiratory viruses. This included the common cold or flu.
“They’re much more effective. In fact, one of the authors that we quote in the paper commented that the RT-PCR test is not the gold standard anymore. It’s the dog. And they’re so quick,” he added. “They can give you the yes or no within seconds if they’re directly smelling you.”
How was the study conducted to see if dogs can really detect Covid-19?
In some studies, the dogs gave a person a quick sniff, sitting down to see if the person has Covid. In another study, the dog was given a sweat sample to smell for a few minutes.
The press release has said that scent dogs, such as beagles, basset hounds and coonhounds are the ideal candidates for sniffing out the virus, given their “natural tendencies to rely on odours to relate to the world.”
But the studies which the researchers analysed showed a variety of dogs were up for the challenge and were able to sniff out the Covid odour. With a few weeks of training, puppies, older dogs, purebred and mixed breeds, both male and female were able to sniff such odours out and “all performed admirably,” the Eureka Alert press release said.
Although there has been success with dogs detecting such viruses, researchers believe there are still many challenges with using dogs for medical diagnoses.
“There’s quite a bit of research, but it’s still considered by many as a kind of a curiosity,” said Professor Dickey.
In conclusion, Professor Dickey and Junqueira said after reviewing the studies, believe that scent dogs deserve “their place as a serious diagnostic methodology that could be particularly useful during future pandemics, potentially as part of rapid routine health screenings in public spaces.”
“Perhaps, most importantly, we argue that the impressive international quality and quantity of COVID scent dog research described in our paper for the first time, demonstrates that medical scent dogs are finally ready for a host of mainstream medical applications,” they added.
