Canine coronavirus (CCoV) is not the same virus as SARS-CoV-2 that causes COVID-19. Canine coronavirus is an enveloped, positive-sense, single-stranded RNA virus which is a member of the species Alphacoronavirus. It causes a highly contagious intestinal disease worldwide in dogs1.
Recently, a second type of canine coronavirus (Group II) has been shown to cause respiratory disease in dogs. Known as canine respiratory coronavirus (CRCoV) and found to be similar to strain OC43 of bovine and human coronaviruses, it was first isolated in the United Kingdom in 20032. (see: Wikipedia)
