Lo and behold, this very interesting and deep rabbit hole of a Wikipedia article: https://en.wikipedia.org/wiki/List_of_common_misconceptions

If that wasn’t enough here is an even deeper rabbit hole: https://en.wikipedia.org/wiki/Wikipedia:Unusual_articles

That was a fun read Thanks for sharing

The dogs sweating one seems like a quibble. I think what most of us heard/understood is that dogs can’t sweat (because of the fur), so they use their mouths/tongue. Okay, apparently they can sweat through their foot pads, but since those are on the ground I doubt they’re getting much evaporative cooling there. This says they regulate temperature through panting, which seems awfully close to the “myth.”
