Using the dog’s nose to sniff out positive Covid cases!
I follow Tony and I have been across to his blog before One Regular Guy Writing about Food, Exercise and Living Past 100.
But on the 15th February Tony came up with a brilliant idea; read it for yourself:

Dogs’ highly evolved noses can rapidly detect the SARS-CoV-2 virus
For some 15,000 years, dogs have been our hunting partners, workmates, helpers and companions. Could they also be our next allies in the fight against COVID-19? As a dog owner with a small poodle who could sniff out a chicken bone in the middle of a football field I was not surprised to learn this.
According to UC Santa Barbara professor emeritus Tommy Dickey and his collaborator, BioScent researcher Heather Junqueira, they can. And with a review paper published in the Journal of Osteopathic Medicine they have added to a small but growing consensus that trained medical scent dogs can effectively be used for screening individuals who may be infected with the COVID-19 virus.
This follows a comprehensive survey of research devoted to the use of trained scent dogs for detecting COVID. “The most striking result is that studies have already demonstrated that dogs can identify people who are COVID-19 positive,” Dickey said of their findings. “Not only that,” he added, “they can do it non-intrusively, more rapidly and with comparable or possibly better accuracy than our conventional detection tests.”
Not surprisingly, the magic lies in canine sense of smell, which gives dogs the ability to detect molecules in tiny concentrations — “one part in a quadrillion compared with one part in one billion for humans,” according to the paper. Add to that other optimizations for smell, such as a large nasal area and the structure of their noses, which allows inflow through the nostrils and outflow through nasal folds. Further, with 125-300 million olfactory cells and a third of their brains devoted to interpreting odors, dogs are well equipped with the ability to sniff out the volatile organic compounds that indicate the presence of COVID.

I must gently disagree with Tony’s opening statement. Dogs evolved from the grey wolf something like 23,000 years ago.
But what a great article and will we see the authorities take him up on the idea? I certainly hope so.
I know dogs can detect cancer. The fact that they can detect COVID-19 is great news.

I guess, Susan, it was to be expected of our lovely dogs. Now to see if the authorities do anything soon?

I more than liked it, Tony, it is a fabulous idea and one that really should be adopted by the health authorities around the world.

I may be mistaken, but I think they are training dogs already to detect this scent. I’m sure they will start with airports and go from there. It takes time and lots of money to train dogs to identify an individual scent from all others. They are just brilliant for detecting so many things.

Marlene, I hope you are correct. We aren’t very good in keeping up with news from the rest of America.

I watch the news after it has been recorded. I put it in fast forward with the sound off. If there is something I need or want to know about, I can stop and listen then continue to bypass the garbage. That’s how I found out about the dogs sniffing out covid. I can’t handle the stress of news so I keep it to a minimum.

We just don’t watch American TV, Marlene. We have an antenna but rarely use it.

That’s hardcore, Paul!!! Wow! I do understand why though. Most is too dumb for words and we wonder why so many here can’t think. I love science and documentaries unlike many females in my generation. Leaves me on the fringes a lot. 😉

Ultimately, Marlene, the real truth about stuff comes from science. That’s not to deny the role, the important role, that philosophy has. I could say a lot more!

If memory serves me, the Miami Heat basketball team plan to use COVID sniffing dogs once fans are allowed back to see games. Dog noses are truly amazing!

Truly amazing, indeed, Monika. One just can’t imagine how dogs smell the world around them.
