A New, Mysterious Respiratory Disease Threatening Dogs Across the Country
Dog owners across dozens of states are growing alarmed by recent outbreaks of a novel respiratory illness that has sickened pets and defied identification. First detected in Michigan fall 2022, the unexplained sickness has since rapidly spread to dogs in many regions nationwide.
The still-unnamed virus produces influenza and pneumonia-like symptoms, with coughing, nasal discharge and difficulty breathing among the most common signs. Though its spread seems to correlate with visits to doggie daycares or boarding facilities during peak holiday travel times, much remains unknown about the origins, exact causes and optimal treatment protocols.
Rising Cases and Hospitalizations Over the Past Months
In August 2022, local vets in Otsego County, MI logged the first cases of what appeared to be a new respiratory infection affecting dogs in the area. Lab tests for known pathogens like flu, parainfluenza and other common culprits came back negative across sickened pets.
By November, dozens more mysterious upper respiratory cases emerged at veterinary hospitals across Michigan. Around Thanksgiving, similar reports began surfacing in states like Indiana, Tennessee and New York. Throughout December, incidents increased exponentially, with dogs now falling ill in over 30 states coast to coast.
Transmission Patterns and At-Risk Dogs
Many of the first identified cases had a recent history of visiting dog daycares and boarding kennels in the week preceding symptom onset. This suggests a highly contagious virus easily spread through close dog-to-dog interactions and contact with shared food/water bowls or toys.
Virtually all breeds and ages have proven susceptible so far. Though most confirmed illnesses have involved younger dogs under age 2, pups, adolescents and senior dogs alike seem vulnerable to catching the virus.
Signs and Symptoms
Within just days of exposure, dogs tend to start exhibiting upper respiratory infection signs resembling kennel cough or canine flu. However, the illness appears potentially more severe.
Early symptoms typically include:
- Dry, harsh or wheezing cough
- Thick nasal discharge - initially clear but later yellowish or greenish
- Rapid, labored breathing
- Low energy, loss of appetite/drinking
- Fever - up to 104F+
In worsening cases, dogs may develop pneumonia-like breathing troubles or require hospitalization for oxygen support. Some bloodwork changes like elevated white cell counts and low lymphocytes are also emerging as patterns with the virus.
Diagnostic Difficulties
Confirming the exact cause has challenged vets in affected regions. Nasal swabs, cultures and blood tests for over a dozen common respiratory pathogens like parvo, adenovirus 2, distemper and various bacterial infections remain negative.
Differentials have encompassed known illnesses presenting unusually to species-specific diseases like Streptococcus equi zooepidemicus. But clinical presentations dont perfectly match, leaving doctors stumped. Advanced infectious disease lab testing seeking genetic traces of possible novel viruses is pending.
Treatment Course Remains Uncertain
With the causative agent still elusive, vets have no standardized guidelines for treating afflicted pets. Supportive therapies like oxygen, fluids, cough suppressants and antibiotics to prevent secondary pneumonia are employed routinely.
Anti-inflammatories and pain relievers may relieve related upper respiratory inflammation and discomfort. Rest and nutritional support facilitate recovery helping dogs restore energy and normalize breathing function.
Though most confirmed cases ultimately recover within 2-3 weeks, hospitalization and rapid treatment significantly improve prognoses especially for dyspneic dogs.
Prevention Practices for Dog Owners
With the holidays mark peak boarding and socialization needs, vigilant precautions are imperative to curb the mysterious outbreak until experts elucidate details.Avoiding Risky Interactions
As congregating dogs under one roof seems to enable viral transmission, limiting visits to indoor daycares, dog parks, groomers and boarding facilities is ideal at this time. Outdoor on-leash walks pose lower infection likelihood.
If boarding remains necessary, opt for single-family environments over large, enclosed centers; inquire about respiratory disease protocols.
Monitoring Health at Home
Watch for coughing, breathing issues, appetite/energy changes and check temperatures twice daily. Record onset dates if symptoms manifest for prompt vet reporting.
Isolate dogs appearing under the weather from other household pets to constrain viral spread.
Pursuing Proactive Care
Keep all shots up to date, including influenza, bordatella, parainfluenza vaccines that may offer partial respiratory illness protection.
Provide immune-boosting nutrition rich in vitamins A, C, E, omega fatty acids, electrolyte supplements and digestive enzymes.
Follow news alerts and emerging health guidance as diagnostic details and treatment insights develop worldwide.
Ongoing Investigations Across Veterinary Medicine Networks
With more dogs falling sick weekly and worries escalating, veterinary groups across academic, industry and government spheres continue collaborating to characterize the elusive virus.
The CDC, USDA APHIS and NIH NIAID are actively partnering with state agriculture departments, universities like Cornell, diagnostic labs, major veterinary hospitals, and pharmaceutical industry connections in the emergency outbreak response.
Optimism remains that the extraordinary collective resources now focused on solving the mystery will soon unlock answers that return our beloved canine companions safely home for the holidays.
