Which group is most at risk for canine parvovirus infection?

• A. Adult dogs
• B. Puppies
• C. Cats
• D. Birds

Answer: (B)

Canine parvovirus infection is most risky for puppies because the virus attacks rapidly dividing cells, especially in the gut and bone marrow, leading to severe diarrhea, dehydration, and immune suppression. Puppies have immature immune systems, and maternal antibodies received through colostrum can interfere with vaccines, creating a window where they are not fully protected yet and can contract the virus. The virus is highly contagious and can persist in the environment, making exposure common in kennels, shelters, and homes with unvaccinated puppies. By adulthood, many dogs have protective immunity from vaccination or prior exposure, reducing their risk. Cats and birds are affected by different pathogens and are not susceptible to canine parvovirus.
