After 3 weeks of stay at a shelter, almost 100% of dogs tested positive for antibodies to CRCoV compared with 30% on the day of entry, indicating that the virus was highly prevalent in the population and was easily transmitted. CRCoV is frequently detected in dogs with clinical respiratory signs and may contribute to the CIRD complex.
