Ellie was a dog like no other. He had an energy and zest for life that was contagious to all who met him. But it wasn’t always that way. Ellie had a rough start to life that left him in a critical situation in front of a hospital. He was emaciated, just like a bag of bones, and he looked as though he had given up on life.
But then something miraculous happened. One day, a group of animal lovers were passing by and noticed Ellie lying there. They could see he was in a critical condition and decided to take him in. They brought him to a nearby vet, examined him, and determined that he had been severely neglected. He was dehydrated, malnourished, and suffering from a number of health problems.
Despite his difficult condition, Ellie’s spirit was still strong. He was a fighter and refused to give up. The vets and animal lovers who had taken him were amazed at his resilience, and they knew that they had to do everything in their power to help him. Over the next several weeks, Ellie received round-the-clock care from a team of dedicated animal lovers. They fed him small amounts of food every few hours to help him regain his strength, gave him fluids and medicine to treat his health problems, and spent countless hours with him providing him with love and attention that he had never received before.
As Ellie began to recover, his personality began to shine through. He was playful, energetic, and loving. He had a zest for life that was infectious, and everyone who met him fell in love with him. Word began to spread, and people from all over the world began to follow his journey on social media.
Despite his newfound fame, Ellie was quite humble and grateful. He knew that he had been given a second chance at life, and he was determined to make the most of it. He began to work with the local animal rescues to help other dogs in need, and he became an ambassador for animal welfare. As Ellie’s story continued to spread, he became a symbol of hope for animals everywhere. People who had never considered adopting a dog before began to change their mind after hearing his story.
Ellie’s journey is a reminder of the resilience of animals and the transformative power of love and care. It’s a testament to the incredible impact that a group of dedicated individuals can make on the life of a neglected and abused animal. Ellie’s story is an inspiration to us all, and we should strive to be more like him, to be fighters and never give up, to be humble and grateful, and to use our experiences to help others in need.
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.
