Why don’t wild animals get ill from drinking dirty outside water whilst we do?

Dirty water (found outside) is portrayed as having all sorts of bacteria, viruses and fungi etc meaning that we can’t drink it without getting very sick. How is it we’ve evolved to have very little tolerance for this meanwhile other animals can drink almost any water found outside and be fine?

Well, we haven't, really. For the vast majority of our existence on this planet we drank the same water as other animals. Over a billion people make do without a source of clean water even today. You rarely get "very sick" from drinking water from a river or a lake, unless it's obviously contaminated in which case other animals tend to avoid it as well.
