A short introduction is given on canine enteric (CECoV) and canine respiratory coronaviruses (CRCoV), members of the genera Alphacoronavirus and Betacoronavirus, respectively. As in other European countries both viruses also circulate in Austrian dog populations. The clinical importance of CECoV has already been demonstrated. In the case of CRCoV, current knowledge of its clinical importance is limited, but CRCoV may be assumed to contribute to canine infectious respiratory disease. Diagnostic investigations, especially of CECoV, may be indicated. Because of the genetic variability of coronaviruses and the possibility of interspecies transmission events, further epidemiological investigations are needed.
