Which of the following is a potential complication of dog flu?

• A. Hair loss
• B. Pneumonia
• C. Sneeze
• D. Nasal discharge

Answer: (B)

Dog flu is a contagious respiratory virus. While many dogs experience coughing, nasal discharge, sneezing, and fever, the infection can damage the lungs and set the stage for pneumonia, a serious complication. Pneumonia occurs when the virus or the accompanying bacterial invaders cause inflammation and infection inside the lungs, leading to symptoms like increased breathing effort, persistent cough, fever, and lethargy. It can be more severe in puppies, older dogs, or those with other health issues and may require veterinary care such as antibiotics for secondary bacterial infection, fluids, and possibly hospitalization or oxygen therapy. The other options describe symptoms of the disease rather than a complication: sneezing and nasal discharge are common signs, and hair loss is not typically associated with dog flu.
