Welcome to our dedicated page on the emerging mystery canine respiratory illness that has been causing concern among pet owners and veterinarians alike. Here’s what we know so far:

What is the mystery dog illness?

Dogs affected by this unknown respiratory illness show symptoms such as persistent coughing, sneezing, eye or nose discharge, excessive fatigue, and a lack of positive test results for common respiratory diseases. The illness can last for weeks to months, with an increase in cases of pneumonia noted.

Transmission is linked to close contact among dogs, making places like daycares, dog parks, groomers, and boarding kennels potential hotspots.

How widespread is the mystery illness?

Reports indicate over 200 cases in Oregon between mid-August and mid-November, with a similar trend in Colorado. Persistent coughs lasting weeks or longer have been observed, contrary to the usual fall decline.

The progression of the illness

The illness can manifest in three ways: a mild to moderate cough, chronic pneumonia unresponsive to antibiotics, and severe pneumonia with poor outcomes within 24 to 36 hours.

How many dogs have died?

Exact fatality figures are challenging to determine due to limited tracking. Some fatalities have been reported, but specific numbers are not available.

Why is respiratory illness in dogs on the rise?

Though gaining attention in 2023, the mystery illness has been present since the previous year. Ongoing studies seek to define the illness, as identifying cases is challenging due to various causes of coughs in dogs.
