How long do signs of dog flu last?

• A. A few hours
• B. Months
• C. A few days to several weeks
• D. Years

Answer: (C)

Signs of canine influenza typically run an acute course, lasting from a few days to several weeks. Most dogs develop coughing, nasal discharge, fever, and lethargy, and these symptoms usually improve within about one to two weeks. However, coughing can linger for two to three weeks or longer, and some dogs may develop a secondary bacterial infection that extends the duration. The other options don’t fit because lasting only a few hours is too short for an influenza infection, while months or years are far longer than expected for the acute phase of dog flu. If signs persist beyond a few weeks or worsen, a veterinary check is important to rule out complications.
