===COVID-19 detection===

Some countries have trained dogs to detect COVID-19. Australia has been using some of these in 2021.<ref>{{cite news |url=https://www.abc.net.au/news/rural/2021-09-07/sniffer-dogs-detecting-covid/100436934 |title=Job of sniffing out COVID cases given to canine recruits |newspaper=ABC News |date=6 September 2021}}</ref>

Researchers in Paris in March 2022 reported in a preprint not yet peer-reviewed that trained dogs were very effective for rapidly detecting the presence of SARS-Cov2 in people, whether displaying symptoms or not. The dogs were presented with sweat samples to smell from 335 people, of whom 78 with symptoms and 31 without tested positive by PCR. The dogs detected 97% of the symptomatic and 100% of the asymptomatic infections. They were 91% accurate at identifying volunteers who were not infected, and 94% accurate at ruling out the infection in people without symptoms. The authors said "Canine testing is non-invasive and provides immediate and reliable results. Further studies will be focused on direct sniffing by dogs to evaluate sniffer dogs for mass pre-test in airports, harbors, railways stations, cultural activities, or sporting events."<ref>{{citation |last1=Grandjean |first1=Dominique |last2=Elie |first2=Caroline |last3=Gallet |first3=Capucine |last4=Julien |first4=Clotilde |last5=Roger |first5=Vinciane |last6=Desquilbet |first6=Loïc |last7=Alvergnat |first7=Guillaume |last8=Delarue |first8=Séverine |last9=Gabassi |first9=Audrey |last10=Minier |first10=Marine |last11=Choupeaux |first11=Laure |last12=Kerneis |first12=Solen |last13=Delaugerre |first13=Constance |last14=Le Goff |first14=Jérôme |last15=Treluyer |first15=Jean-Marc |title=Diagnostic Accuracy of Non-Invasive Detection of Sars-Cov-2 Infection by Canine Olfaction |journal=PLOS ONE |publisher=Cold Spring Harbor Laboratory |date=8 March 2022 |volume=17 |issue=6 |pages=e0268382 |doi=10.1371/journal.pone.0268382|doi-access=free |medrxiv=10.1101/2022.03.07.22271219 |pmid=35648737 |pmc=9159600 |bibcode=2022PLoSO..1768382G |s2cid=247291441}}</ref><ref>{{cite news |title=Dogs Sniff Out Coronavirus With High Accuracy |agency=Reuters |website=Medscape |date=10 March 2022 |url=https://www.medscape.com/viewarticle/970028?uac=88149SY&faf=1&sso=true&impID=4142618&src=mkm_ret_220406_mscpmrk_psych_pets }}{{Dead link|date=January 2024 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
