Meet Mixi, a brave dog who had been suffering from a massive tumor under his chest for a long time. The tumor was so large that it hung down and touched the ground when he moved, causing him immense discomfort. Desperate for help, Mixi went near a car, hoping to find someone who could assist him.
Fortunately, kind-hearted individuals came to his rescue and took him to a veterinary hospital to receive treatment. The pictures taken before the surgery showed the extent of the tumor, which was heavy and had broken through the skin, leaving a gaping hole. But thanks to the successful surgery, the tumor was completely removed, giving Mixi a new lease on life.
After the surgery, Mixi was brought back to his home, where he eagerly awaited the arrival of his owner, a woman wearing a blue shirt. He seemed to have a lot to say to her, and his excitement was palpable. His owner was emotional and grateful to the people who had saved her beloved dog’s life. She expressed her heartfelt thanks and appreciation for giving Mixi a chance at a happy and healthy life.
Despite still needing care and medication for the healing process, Mixi’s owner was hopeful that he would fully recover and not have any further health issues. She shared her story, describing the pitiful state Mixi was in before the surgery and how she had feared that he might not survive. However, she now believed in miracles as she saw Mixi’s remarkable progress.
Mixi’s owner expressed her deep gratitude to the kind-hearted individuals who had helped her dog and gave him a second chance. She thanked them from the bottom of her heart and looked forward to a brighter future with Mixi by her side, now able to run freely and enjoy life to the fullest.
Mixi’s story is a heartwarming reminder of the incredible resilience and strength of animals and the transformative power of compassion and care. It is a testament to the dedication of veterinary professionals and the kindness of strangers who stepped forward to help an innocent animal in need. With a bright future ahead of him, Mixi’s journey is a true testament to the unwavering bond between humans and their furry companions, and a story of hope and healing that will inspire many.
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.
