Animals Good


The University of Pennsylvania recently started a program to train dogs to detect COVID-19 in humans. Similar programs are underway in other countries.

Dog noses have up to 300 million scent detectors (humans have around six million). These sensitive snouts allow them to sniff out volatile organic compounds created by certain cells.

Trainers hope that the first group of COVID-19 sniffing dogs will be ready to go to work by July. They can then help with detecting the virus in asymptomatic people, which may aid in efforts to minimize public exposure to the illness.

I’m sure those good doggos would appreciate some treats. I can’t give them one, but I can dedicate today’s cuppa to them. Here’s to the 1,000,000,000 reasons – and now one more – that dogs make the world a better place.
