I know dogs have 2D vision for sure, which is why they can't tell the distance of an object; if that relates to what they can actually see or not and if that has anything to do with the pupil or formation of their head is unknown for me, I'm not much of a professional in this stuff lol.
Navigating a 3 dimensional world with only 2 dimensional vision seems like an awful waste of brainspace to me, it gives you useless information, and vision takes up an awfully disproportionate amount of brain power.
