"Decline in Mysterious Dog Respiratory Illness Cases in Colorado"
A surge of mysterious respiratory illnesses in dogs, known as canine infectious respiratory disease complex (CIRDC), has abated after peaking in late 2023, with cases dropping to usual levels within the first few weeks of January. The cause of the wave and its subsequent decline remains elusive, with no single pathogen identified as solely responsible. While concerns arose about a potential link to Covid-19, experts have ruled out SARS-CoV2 as the driving force behind the illnesses. As the situation stabilizes, veterinarians advise dog owners to consider the risks and benefits of returning to dog parks and other social settings, emphasizing the importance of vaccinations and understanding individual risk factors for each dog.
