Dogs can sniff out SARS-CoV-2 in urine samples with 96% accuracy, according to a proof-of-concept study.

No more swabs being jammed up your nose? Not quite, as the “dog test” is a long way off from practical applications. That’s because the dogs could only distinguish between positive and negative results in samples that they had trained with; they failed to detect SARS-CoV-2 when presented with completely new samples.

Dogs are known to be able to sniff out scents that are specific to various diseases, and previous studies have shown that SARS-CoV-2 also has a strong signature that dogs can detect in saliva and sweat samples. In fact, dogs have already been deployed to detect COVID-19 at a Dubai airport, according to the study. But it wasn’t known whether dogs could detect the virus in urine samples, where the virus load is typically lower, according to the study.
