Think you might have COVID? Ask your dog - study

Governments and households around the world spent fortunes during the COVID-19 pandemic on equipment to detect an infection. The part of a dog’s brain that is devoted to analyzing smells is about 40 times greater than ours. All these enhancements mean that dogs can detect very low concentrations of odors associated with COVID infections. Emeritus Tommy Dickey said. In one study, a “problem” pit bull terrier that had been abused found a second chance by becoming a perfectly capable COVID detector.
