Some scientists believe that our canine friends can play a very important role in defeating this deadly virus. This hypothesis was proposed by experts from the Medical Detection Dogs found in the UK. They say that every disease such as malaria, Parkinson’s, and cancer has a unique odor. In this regard, they have trained specialist sniffer dogs to spot these diseases. If they could train these sniffer dogs to sniff cases of coronavirus, they would help prevent the spread of the virus.
