Dogs, domestic and wild, are readily distinguished from people. They do not just look different, they evolved quite independently from humans. Like humans, they functioned as pursuit predators living in social groups. Each species, however, evolved along very different paths. Dogs are optimized for a sense of smell, good vision in dim light, and hearing in ranges that best detect prey. Dogs, therefore, do not experience the world the way we do. Learning how their senses differ from ours will help you understand your dog better, and will give you a different perspective on the natural world around us with more than just a canine view of the world.
