Your task is to predict the verdict of a claim based on the provided question-answer pair evidence. The possible labels are: 'Supported', 'Refuted', 'Not Enough Evidence', 'Conflicting Evidence/Cherrypicking'. Justify your answer using the provided evidence and select the correct label.

Claim: Dogs can smell COVID-19 on humans.

Q1: Can sniffer dogs be used to detect Covid-19?
A1: Yes, because Around the world, canines are being trained to detect the whiff of COVID-19 infections.

Q2: Where have Covid 19 sniffer dogs been trialled?
A2: Helsinki, Finland

Q3: Are sniffer dogs being used to detect Covid-19?
A3: There is variation in how well individual dogs perform, trial groups need to boost their sample sizes before the wider scientific community can evaluate how useful the dogs might be.

Q4: What have studies found about sniffer dogs detecting COVID-19?
A4: A group in France, led by veterinary scientist Dominique Grandjean at the National Veterinary School of Alfort near Paris, posted its work3 on the preprint server bioRxiv in June. The researchers, who included Sarkis, trained 8 dogs to detect COVID-19 in 198 sweat samples, around half of which were from people with the disease. When these were hidden in a row of negative samples, the dogs identified the positive samples 83–100% of the time. The paper does not say how well the dogs identified negative test results. The research is now under review at a journal, but Grandjean says the process has not been easy. “To publish papers on detection dogs is very difficult because most reviewers do not know anything about working dogs,” he says.

The data in that study look promising, says Fyodor Urnov, a gene-editing scientist who is working on COVID testing at the University of California, Berkeley. But he would like to see larger data sets on how well dogs identify positive and negative samples. He also notes that there is variation in how well individual dogs perform. In Grandjean’s study, for example, 2 dogs identified 68 out of 68 positive samples, whereas one missed 10 out of 57 cases.

Q5: Do the studies find that using sniffer dogs to detect COVID-19 is useful?
A5: Groups need to boost their sample sizes before the wider scientific community can evaluate how useful the dogs might be, agrees James Logan, an infectious-disease researcher at the London School of Hygiene & Tropical Medicine who is training and studying COVID-19 dogs, including Storm, Maple and Asher. “It’s important not to go out too early with grand claims and small data sets,” he says.

justification: Specially trained dogs are being Trained and trials are being performed however the claim implies all dogs can smell covid-19.
