Canine respiratory coronavirus (CRCoV) was first detected in a dog in 2003. It appears to have originated from bovine coronavirus, since both viruses share very close similarities.
In general, respiratory coronavirus can frequently be detected in the majority of dogs suffering from kennel cough (also known as canine infectious respiratory diseases (CIRD) complex).
In many dogs with mild or moderate signs, such as cough or nasal discharge, but also in asymptomatic dogs, the virus can mainly be found in the trachea.
