"Unexplained Dog Illness Spreads Across US: Symptoms to Watch for"

A mysterious and potentially fatal respiratory illness is affecting dogs in multiple states, including Illinois. The illness starts as a cough and worsens over time, with symptoms such as coughing, sneezing, discharge from the eyes or nose, trouble breathing, and fatigue. The illness is resistant to antibiotics and can be contracted through contact with other dogs in places like dog parks, kennels, and groomers. Dog owners are advised to seek veterinary care immediately if their dogs exhibit symptoms and to keep them away from sick dogs and large groups of unknown dogs. Vaccinations and PCR testing are recommended for prevention and diagnosis.
