Atypical Canine Infectious Respiratory Disease

The Board of Animal Health has received reports of an increase in the incidence of canine infectious respiratory disease (CIRD) from veterinarians across the state. This increase is similar to what is being observed across the country this year. The majority of cases appear to follow the expected course and clinical characteristics of typical CIRD, with most dogs experiencing mild illness and a smaller percent having severe illness progressing to pneumonia or prolonged disease.

Significant media attention has focused on atypical CIRD (aCIRD) infections. aCIRD is defined as severe, acute respiratory disease in dogs without underlying risk factors (senior dogs, puppies, brachiocephalic, preexisting respiratory disease) that is refractory to routine, recommended treatment. aCIRD does not appear to be widespread in Minnesota at this time.

While a single infective agent has not been identified as the cause of the majority of aCIRD, PCR testing remains important for treatment recommendations and disease management. Samples for PCR need to be taken early in the course of disease for accurate results. PCR testing will be most accurate if done in the first 2 - 4 days of clinical illness. Respiratory panels are available through University of Minnesota VDL as well as commercial labs. Kansas State Veterinary Diagnostic Laboratory is offering testing free of change for a limited time in search of a causative agent. Before collecting and submitting any samples you should call the laboratory where you would like submit because they have very specific collection and transport requirements.

The Board recommends dog owners, dog businesses, and veterinarians follow our canine influenza guidance to help stop the spread of any respiratory infection.

• Keep sick dogs at home and isolated from other dogs for 30 days.
• Avoid contact with sick dogs and consider leaving pets at home when visiting other households with dogs.
• Ensure all recommended vaccinations are up to date.
• Be aware that some dogs are at higher risk of more severe disease and may require early intervention. These include dogs that are: puppies, seniors, have underlying health conditions, and brachycephalic breeds.
• Practice good cleaning and disinfection and biosecurity protocols.

Veterinarians can report cases of aCIRD and canine influenza to the Board through the case report form on the Board’s website or by sending us an email.

The Board will update guidance and information as the situation evolves.
