Canine Coronavirus - Canine Respiratory Coronavirus

Canine Respiratory Coronavirus

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 2003 from lung samples of dogs and has since been found on the European mainland and in Japan. A serological study in 2006 has also shown antibodies to CRCoV to be present in dogs in Canada and the United States. However, a retrospective study in Saskatchewan found that CRCoV may have been present there as far back as 1996.
