They say just like human fingerprints, no two dogs' nose prints are alike. Also, your dog can smell your feelings. In fact, your dog’s sense of smell is approximately 100,000 times better than yours. So it shouldn’t be shocking that they can in fact, smell things such as fear. When a human is fearful, they perspire, and a dog is easily able to pick up on this change.

For the above facts, I wanted to focus on the dog's snout more specifically the "Rhinarium", commonly known as a "Wet Nose".
