Mysterious Respiratory Illness Affecting Dogs Across Several US States

With over 200 cases documented in Oregon alone, veterinarians are working to identify the cause of the disease that has led to confirmed fatalities.

A mysterious respiratory illness is affecting dogs in several US states, including Oregon, Colorado, and New Hampshire, causing lasting disease and pneumonia that does not respond to antibiotics.
Symptoms include coughing, sneezing, nasal or eye discharge, and lethargy, with some cases progressing quickly to severe illness within 24 to 36 hours.
The Oregon Department of Agriculture has documented over 200 cases since mid-August and is working with state researchers and the U.S. Department of Agriculture’s National Veterinary Services Laboratory to identify the cause.
While it's difficult to determine the exact number of fatalities due to the lack of a clear definition or test for the disease, it is confirmed that dogs have died from this illness.
Veterinarians are urging dog owners not to panic, but to ensure their pets are up-to-date on vaccines and to decrease contact with other dogs.
