Which statement about dog flu is true?

• A. Neither virus is contagious to humans
• B. Dog flu is deadly to most dogs
• C. Puppies and old dogs are less at risk
• D. The viruses are seasonal

Answer: (A)

The main idea here is whether dog flu can infect humans. Canine influenza viruses mainly spread between dogs through respiratory droplets and contaminated surfaces, and there isn’t strong, consistent evidence that these viruses infect people under normal exposure. That’s why the statement about neither virus being contagious to humans is the best choice. The other ideas aren’t accurate: dog flu isn’t deadly to most dogs—many cases are mild or resolve with care, and vaccination can reduce risk. Puppies and older dogs can be more at risk for severe illness, not less. And the viruses aren’t strictly seasonal; outbreaks can occur year-round, though there may be regional patterns or peaks in some circumstances.
