Introduction

A mysterious respiratory illness has affected dogs across the United States, particularly in Oregon and New Hampshire. As of the publication date, no cases of this disease have been recorded in Virginia or at the Veterinary Teaching Hospital in Blacksburg. This advice is derived from online sources, conversations with other veterinary and Public Health professionals, and within the Veterinary College. This guide aims to assist veterinarians, pet owners, and businesses such as groomers, pet shelters, and dog parks in understanding and managing this emerging outbreak. 

We strongly advise that you also keep abreast of any notifications and alerts from veterinary and health agencies and veterinary bodies such as the AVMA and VVMA, as well as your local veterinarian. 

It is important to remember that the number of dogs currently known to have been sick is a small percentage of the overall dog population. The number of states reporting cases is 14, according to the American Veterinary Medical Association (AVMA).

Understanding the Illness

  • Symptoms: The illness resembles a kennel cough but is more severe, lasting longer, and does not respond to common antibiotics. Symptoms include coughing, nasal and eye discharge, and sneezing. In some rare cases, it has been fatal.

  • Current Research: It's unclear if this situation represents a single disease outbreak. Current data doesn't link these incidents to a specific pathogen or suggest the emergence of a new one. The lack of a comprehensive system for monitoring infectious diseases in dogs in the United States complicates efforts to track and understand these occurrences.

  • One theory is the presence of a "pathogen soup," a combination of several infections simultaneously affecting dogs and delaying their recovery.

Prevention and Management

  • Vaccinations: Ensure all dogs are up to date with vaccinations, including bordetella, canine influenza, and parainfluenza.

  • Avoiding Exposure: Consider avoiding crowded dog areas in regions with reported cases. Increased precautions are sensible in areas with many sick dogs, especially for dogs more susceptible to illness.

  • However, neglecting regular veterinary care due to fear of infection is discouraged.  

  • Monitoring Symptoms: Watch for signs of infection and seek veterinary care if symptoms appear.

"No specific preventative measures or treatments are known now, and the likely timeline of development/understanding of these is long, so the above measures are the best choice."

For Veterinarians

  • Diagnostic Approach: Be aware of the symptoms and consider this new illness in differential diagnoses, especially for cases unresponsive to standard treatments.

  • Research Participation: Report cases and consider collaborating with state and agency research labs for sample submission and updates on the disease.

For Pet Owners

  • Observation: Monitor your dog for any signs of respiratory distress.

  • Veterinary Consultation: Consult your veterinarian if your dog shows symptoms. Discuss the possibility of this new illness.

  • Public Health Practices: Apply basic health practices like cleaning and disinfecting your dog's living spaces.

For Dog Care Businesses

  • Disinfection: Regularly clean and disinfect facilities.

  • Client Education: Inform clients about the illness, its symptoms, and the importance of vaccinations. I suggest they do not bring their dog if it is showing symptoms.

  • Event Management: Be cautious about organizing or participating in events with large gatherings of dogs in affected areas.

Conclusion

While this respiratory illness in dogs is concerning, it is essential to approach it with caution and informed care. Keep abreast of the latest research and guidance from veterinary health experts. Collaboration and proactive health measures are vital in managing this emerging health issue in dogs.
