Executive Director of the Washington Animal Disease Diagnostic Lab Kevin Snekvik, whose facility has been researching the condition, described the illness’s symptoms in an interview with KIRO7. 

“Your dog will run a fever and they won’t feel good,” Snekvik said. “They’ll become lethargic, meaning they want to lie around more when normally they’d be wanting to play outside… and the coughing part of it, that becomes more productive like a wet cough, like a hacking cough.”

Per the Oregon Department of Agriculture, symptoms also include sneezing, eye or nose discharge, fatigue, blue or purple gums from oxygen deprivation, trouble breathing and negative tests for other common respiratory illnesses.
