Plain-English summary
A group of dogs at a training center experienced outbreaks of respiratory disease, known as canine infectious respiratory disease (CIRD). During the study, researchers took swabs and blood samples to check for viruses and antibodies. They found that one kennel had seasonal outbreaks linked to canine respiratory coronavirus (CRCoV), while the other kennel had fewer cases and showed high levels of antibodies to CRCoV but no active infections. Ultimately, the study highlighted the presence of CRCoV as a significant factor in respiratory illness among the dogs in the affected kennel.

Abstract
Two training centres for working dogs were monitored for one year to determine the presence of viruses and viral antibodies and their association with canine infectious respiratory disease (CIRD). Tonsillar swabs and serum were obtained from dogs on entry into the kennels and in regular intervals thereafter. Additional samples were collected during outbreaks of CIRD. The swabs were examined by virus culture and PCR for canine parainfluenza virus, canine adenovirus, canine herpesvirus (CHV) and canine respiratory coronavirus (CRCoV). Furthermore the prevalence of antibodies to CHV and CRCoV was determined. During this study CIRD was reported mainly in one of the two kennels investigated. In that kennel antibody responses to CRCoV indicated a seasonal occurrence of the virus, which coincided with two outbreaks of respiratory disease. CHV antibody responses were detected throughout the year. In the other kennel, which reported few cases of CIRD a high prevalence of antibodies to CRCoV was detected on entry but only sporadic seroconversions to CRCoV or CHV. By PCR three dogs were found positive for CRCoV in one kennel whereas all PCR tests for other viruses were negative for both kennels. Virus culture failed to detect any viruses in either kennel.
