A vet in Germany has claimed to have trained sniffer dogs to detect coronavirus in human saliva samples with up to 94 per cent accuracy.
The dogs are conditioned to sniff out the "corona odour" that comes from cells in infected people, said Esther Schalke, a vet at Germany's armed forces school for service dogs.
Holger Volk, head of the veterinary clinic said: "We did a study where we had dogs sniffing samples from Covid-positive patients and we can say that they have a 94 per cent probability in our study ...
that they can sniff them out. "So dogs can really sniff out people with infections and without infections, as well as asymptomatic and symptomatic Covid patients." Filou, a 3-year-old Belgian Shepherd, and Joe Cocker, a 1-year-old
