Four more states have reported strange dog illnesses: How to keep your pets safe
This mysterious ailment appears in dogs with coughing, sneezing, eye or nasal discharge, atypical fatigue, and no common respiratory illness reasons.
This mysterious illness outbreak is marked by the large number of canines suffering pneumonia.
The Colorado Department of Agriculture said that "veterinarians (in the state) are currently reporting that they are seeing double the number of cases than what is typically seen during a canine infectious respiratory disease outbreak."
Dogs with contagious coughs are common in veterinary settings, but Cavanagh says rates decrease in the fall as temperatures drop and fewer dogs are at parks.
