In a quiet corner of the animal shelter, a man named John arrived with the intention of adopting a Pit Bull named Max. Max, a resilient and gentle soul, had been through a tumultuous journey before finding refuge in the shelter. His striking features and warm brown eyes had caught John’s attention through an online adoption profile.
As John entered the shelter, a wave of anticipation mixed with nervousness washed over him. He had read about Max’s past struggles and was determined to provide him with a loving home. The shelter staff greeted John warmly, leading him to Max’s enclosure.
Upon reaching Max’s kennel, John was met with an unexpected sight. Max, a robust and muscular Pit Bull, was not alone. Nestled beside him was a smaller, frail dog with expressive eyes that mirrored Max’s own kindness. The bond between the two was palpable, and it became evident that they were inseparable companions.
Curiosity and compassion overcame John as he inquired about the smaller dog’s story. The shelter staff explained that the smaller dog, named Buddy, had been rescued alongside Max from an abusive environment. The two had formed an unbreakable bond during their time at the shelter, providing each other comfort and solace.

As John observed the dynamic between Max and Buddy, a realization dawned on him. Adopting Max meant adopting Buddy as well, for their connection was a testament to the strength of their companionship. Undeterred by the unexpected twist, John decided to open his heart and home to both dogs, acknowledging the profound impact they had on each other.
The adoption process unfolded with paperwork and joyful tail wags. Max and Buddy, now aware that their lives were about to take a positive turn, emanated gratitude in their every glance. As they left the shelter, John could feel the gratitude and loyalty radiating from the two dogs, and a sense of fulfillment settled within him.
Back at John’s home, Max and Buddy seamlessly integrated into their new surroundings. It became evident that their bond wasn’t just born out of shared adversity but was a testament to the resilience of love and the healing power of companionship. Max, initially adopted for his strength and protectiveness, showed a tender and nurturing side when it came to looking out for Buddy.
In the weeks that followed, John witnessed the transformation of the two dogs. Max’s once guarded demeanor softened, and Buddy, once timid and fearful, blossomed under the reassuring presence of his loyal friend. Their story became a beacon of hope for the shelter staff and an inspiration for others considering pet adoption.
The narrative of Max and Buddy demonstrated that adoption is not merely a one-way act of kindness; it is a reciprocal exchange of love and trust. John, thinking he was saving Max, found himself equally saved by the unwavering friendship of these two resilient souls. The once broken spirits of Max and Buddy mended each other, creating a harmonious melody of healing in the quiet corners of John’s home.
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.
