We know. Please stop emailing us. We at The Scholarly Kitchen have clearly failed you, our readers, by not supplying enough dog-related content. That ends today, with the video below, which answers the essential questions we all have about what things look like to dogs.
Going back to research from the late 1980s, we learned from a dog named (of course) “Retina”, that unlike humans who have three types of cone cell photoreceptors, dogs only have two. This makes their vision somewhat akin to that of a red/green colorblind human. But that’s perhaps an oversimplification — dogs have far more rod cell photoreceptors than humans, and the arrangement of cells in a dog’s retina differs greatly from that seen in a human.
Perhaps more importantly, dogs have vastly more developed olfactory senses, and this greatly influences their “view” of the world. Which brings us to the term “umwelt“, a word coined to describe the way each individual organism perceives its environment.

3 Thoughts on "How Do Dogs See the World?"
Thanks for sharing that David. It will help me keep in mind how my dog Bailey sees the world differently than I do.
Thanks for this excellent canine content, particularly on a Friday! I must admit I’m also tickled to see a reference to my dad’s umwelt theory.
For a broader review of how the animal planet perceives the world, I recommend Ed Yong’s “An Immense World” https://www.penguinrandomhouse.com/books/616914/an-immense-world-by-ed-yong/.
