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.
Indomitable spirit: The harrowing journey of an abandoned mother dog with a broken neck, overcoming cruelty to find redemption for her poor cubs

It’s a Miracle! Abandoned Pregnant Dog in Critical Condition Still Able to Give Birth to 7 Puppies

On November 11th, a distressing report came in about a pregnant dog in critical condition. The situation was heart-wrenching – the dog had been abandoned in a box with a broken neck, just days away from giving birth. There were signs of violence on her frail body, and her puppies were at risk.
The rescuer who responded to the call, Kola Kariola, described the moment he first saw her as heartbreaking. The dog collapsed in his hands, her belly bleeding profusely. He rushed her to the vet where she received a blood transfusion and was stabilized, but her condition was still dire.

Kola consulted with his vet who recommended moving the dog to a larger hospital for further treatment. Her neck needed surgery to save her life, but they decided to wait until after she gave birth to her puppies. The next 48 hours were tense as the brave dog fought for her life and gave birth to 7 puppies, although 2 of them were stillborn. She was unable to feed her puppies, so Kola and his team had to step in and provide nourishment for them.
Despite the odds, the puppies survived, and it was truly a miracle. The mother dog, who was named Belinha, finally underwent her much-needed neck surgery, which was successful. She was then moved to a special room for post-operative care and observation for 72 hours. It was crucial for her to recover fully before being reunited with her puppies.

Kola expressed his gratitude towards Protetora Carol, who played a crucial role in saving Belinha’s life. It was her quick action and dedication to rescuing animals that brought Belinha to safety and enabled her to receive the medical care she desperately needed.
Belinha’s story is a testament to the resilience and strength of animals, as well as the power of compassionate individuals who go above and beyond to help those in need. It’s a reminder of the importance of reporting cases of animal cruelty and neglect, and taking action to help animals in distress. Belinha and her puppies are now on the road to recovery, thanks to the unwavering efforts of Kola, his vet team, and Protetora Carol. Their story is one of hope, compassion, and the incredible bond between humans and animals.
