No paywall, so read the whole thing:
From New Hampshire to Oregon, researchers are trying to figure out what’s causing an infectious respiratory disease among dogs that has turned deadly in rare cases.
The mysterious illness is described as an “atypical canine infectious respiratory disease,” the Oregon Department of Agriculture said in a November 9 news release. Symptoms include coughing, sneezing, eye or nose discharge and lethargy.
Veterinarians in Oregon have reported more than 200 cases of the disease since mid-August. Other cases have been reported in Colorado, Illinois and New Hampshire.
Not sure if there is anything you can really do other than pay attention if your dog starts to show these symptoms.
