You see all kinds of animals drinking from puddles, ponds, etc and they are fine, whereas us humans can’t do it without getting sick.

Also a lot of animals have shorter GI tracts, so bacterial growth time is shorter. Some also have more acidic stomachs that are better at killing parasites and bacteria.

Overall it’s a lot of survivor bias though. We look at mature animals and think, “how do they survive”, but don’t see the ones who died.
