How dogs see the world: Canine vision and senses

In this article, Brian Faulkner, FRCVS, shares information on how dogs see and smell their environments. Consider it for new dog parents and for newsletters, social media or school visit content. Notable facts include:

• Dogs only have two types of color-sensing receptors and may be red-green color blind
• Most dogs have 20/75 vision; labs are an exception, as many have 20/20 vision
• Dogs have up to a billion smell receptors compared to humans with only 5 million
