Dogs Can Learn New Tricks
If you’ve traveled abroad, you may have encountered dogs sniffing passengers’ luggage for drugs at the airport. Dogs are employed in this occupation because their noses have around 300 million scent receptors making them superior smellers to humans who only have about 5 or 6 million.
I learned about this in an article which appeared in The Wall Street Journal titled, “Your Next Covid-19 Test Could be a Dog’s Sniff”. The other article, which was published by the American Lung Association on the same subject, “Can Dogs Sniff Out COVID-19?” pointed out that dogs can detect different diseases, including lung cancer, Parkinson’s disease and diabetes.
I hope this revelation will bring a new respect for your four-legged friends, like Max, Gus and Mandy.
Enjoy and Share!
