"Identifying Symptoms and Seeking Veterinary Help for the Surging Fatal Dog Illness"

A highly contagious and potentially fatal respiratory illness is affecting dogs in several US states, causing lasting respiratory disease and pneumonia that does not respond to antibiotics. The symptoms, which may last for weeks or even months, include a cough that can turn into pneumonia, similar to kennel cough. Dog owners are advised to bring their pets to a vet if they exhibit consistent coughing or difficulty breathing. To prevent the illness, dogs should be fully vaccinated and avoid contact with other dogs outside their household.
