Research out of the University of Pennsylvania School of Veterinary Medicine Working Dog Center revealed that dogs can identify urine samples from COVID-19-positive individuals with 96% accuracy.
The study, published in April in the journal PLOS ONE, used nine specially trained detection dogs taught to detect coronavirus, as well as discern between positive and negative urine samples.
In the future, dogs might even sniff out COVID at large gatherings like concerts, sporting events and airports similar to the way they are currently used to search for explosives and drugs.
