There was a story in the news this morning (really!), that researchers have determined that dogs can tell who is infected with COVID-19 with 96% accuracy, even before someone is symptomatic.
My dog is scaring me to death. He came over to me just now, wearing a surgical mask and face shield. I think he's trying to tell me something.
Also suspect that when you go to the hospital with COVID symptoms, they will do a DG scan. It's like a CT scan, only with a dog instead of a cat.
