> If the opportunity was given to them, dogs opted for a detour in the case of uncomfortably small apertures
Except in the case of one very sweet but not exactly brilliant large dog I know that legitimately believes his entire body is just the tip of his nose that he can see. I’ve seen him walk straight through a 2” hole in a screen door, and he will repeatedly try to sit on e.g. a chair armrest and not understand why it doesn’t work.
