The grocery store in the Finnish city of Tampere even has an official golden retriever who tests out dog treats and shares the results in Instagram videos.
A ‘su-paw-market’ in Finland is welcoming canine customers, with specially-adapted carts which allow dog owners to bring their pooches grocery shopping.
The Kesko grocery chain in the city of Tampere has introduced the “Koirakärry” – dog cart – as a way to welcome in more dog-owning customers at one of its stores, where usually only service animals would be permitted inside the aisles.
“The idea is already used in some countries, but not in Finland, and we have a lot of dog owners nearby,” explains Matilda Tistelgren, who has been operating the supermarket with her partner Joona Pesonen since the spring.
“We have a golden retriever ourselves, and if we go out jogging with the dog and forget something from the store, we don’t want to go home, leave the dog, then have to return to the store ourselves, we want to be able to take the dog with us,” Matilda tells Euronews.
The carts have a dog bed in the bottom, and a clip for leads or harnesses, with owners encouraged to pick up their pups and put them inside – although a future version of the cart might include a small ramp so the dogs can walk in unaided.
Since taking over the management of the supermarket in Tampere’s neighbourhood Kissanmaa – which funnily enough translates as “Cat’s Land” – Matilda and Joona have introduced other pet-friendly innovations.
The couple’s own retriever Tove appears on Instagram with ‘Tove Tastes’ videos where she samples different dog treats.
“Our customers love it,” exclaims Matilda. “In this part of town we have a lot of dog owners and that means a lot of dog customers too, and we already have a lot of hairy regulars,” she adds.
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.
