A mysterious and potentially fatal respiratory illness in dogs has been reported in several states across the country, as veterinarians continue to search for what may be causing the condition that has killed some dogs.
The illness starts out as a cough that can last for several weeks, but it may not respond to antibiotics, which can leave the dog struggling to breathe and with severe pneumonia.
“It seems to happen very, very quickly — to go from this cough that’s just won’t go away … and then all of a sudden they develop this pneumonia,” Dr. Lindsey Ganzer, veterinarian and CEO at North Springs Veterinary Referral Center in Colorado Springs, Colorado, tells TODAY.com.
