Short answer: Best estimate: roughly 900 million dogs globally as of 2024 – including pets, feral, free-roaming village dogs, working dogs, and shelter populations. Pet dogs alone are estimated at ~470 million. The US has ~89 million pet dogs (AVMA 2024).
What you should actually do
- Global total (all dogs): ~900 million (WHO 2018 estimate extrapolated).
- Pet dogs worldwide: ~470 million.
- US pet dogs: 89 million (AVMA Pet Demographic Source Book).
- China and Brazil have the largest pet dog populations after the US.
- Free-roaming village dogs (not pets): 50-70% of the global dog population.
The global figure is hard to pin down because most free-roaming dogs in low- and middle-income countries are uncounted. The pet dog figure is tracked better through industry surveys.
US pet ownership has grown significantly post-pandemic. About 65% of US households own at least one pet (APPA 2024).
