What is the average lifespan of dogs?

• A. 8-9 years
• B. 16-18 years
• C. 12-14 years
• D. 20-25 years

Answer: (C)

Understanding average lifespan means looking at what a typical dog can expect across a wide mix of breeds and sizes. Lifespan is strongly influenced by size: small dogs often live longer than large ones. When you average across all dogs, a commonly cited range around 12 to 14 years best represents the overall picture, because it balances the longer lifespans seen in smaller breeds with the shorter ones more common in larger breeds. While some individual dogs—especially small breeds or those in excellent health—may reach into the mid to high teens or even higher, and a few exceptionally healthy individuals may live into their twenties, these are not the typical experience for most dogs.
