In the quiet solitude of a deserted street, a small puppy sat forlorn and motionless, embodying a sense of despair that tugged at the heartstrings of anyone who chanced upon its gaze. Tear-filled eyes spoke volumes of the dog’s plight, abandoned and forgotten, left with nowhere to call home. With a heart heavy with desolation, the dog’s only glimmer of hope was to approach a nearby police base, a silent plea for assistance echoing in its every step.
The dog’s destiny hung in the balance, unsure if anyone would heed its silent cries. Yet, propelled by necessity, the pup summoned its courage and approached the door of the police base. As fate would have it, a compassionate policeman stood close by, his attention drawn to the faint knocking. Opening the door, he was met with a heart-rending sight: a little dog, its eyes filled with a poignant mixture of vulnerability and supplication. In that instant, the policeman’s heart melted, swayed by the dog’s touching plea for help. Gently, he inquired, “What brings you here, little one?” In response, the dog mustered a tentative wag of its tail, eyes gleaming with a glimmer of hope. With resolve solidified, the officer scooped up the trembling pup, ushering it into the safety of the police base.
From that moment on, a transformation took place — one that would shape the destiny of both the dog and its newfound protector. The puppy found itself embraced by the warm embrace of the police base, quickly endearing itself to the officers within. Its loyalty and affection became apparent, igniting a genuine bond that resonated throughout the base’s corridors. The dog’s presence became a source of solace and camaraderie, a reminder of the remarkable ability of animals to forge connections that transcend words.
With each passing day, the dog’s life underwent a remarkable metamorphosis. It was given a new name: Lucky, embodying the newfound fortune that had smiled upon it. Lucky’s once desolate existence now blossomed into a life brimming with love, care, and companionship. It proved itself as a faithful and devoted companion, a steadfast friend to those who had taken it in.
Lucky’s story is a testament to the power of compassion and the profound impact that even a small gesture of kindness can have on a life. It serves as a reminder that amid the challenges of the world, there is always room for humanity to shine through. The bond between Lucky and the police officers is a symbol of the unwavering devotion that animals bring into our lives, and the reciprocal love that can flourish when we extend a helping hand.
In conclusion, the heartwarming tale of Lucky, the abandoned dog who found solace within the embrace of a police base, resonates as a testament to the resilience of animals and the boundless capacity of humans to show compassion. Lucky’s journey from despair to hope serves as an inspiration, underscoring the importance of extending empathy to the voiceless and reminding us that every act of kindness creates ripples of positivity that enrich lives in unimaginable ways.
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.
