Dog vision is a trendy topic, but what can we really know about how they see?

Between camera filters and clickbait, the digital world is rife with misleading information about how, exactly, dogs see the world. In this short from the YouTube series Howtown, the US reporter and producer Adam Cole sets out to separate the facts from doggone fiction regarding canine vision. Working through the scientific literature with a series of experts, he discovers some truly fascinating insights into how dogs experience colour and depth, as well as how sight and smell intertwine in a dog’s mind. His investigation also provides an illuminating look into the tools scientists currently possess to understand the interior worlds – or ‘Umwelts’ – of nonhuman animals, as well as the limitations that we may never be able to overcome.
