Just how good IS that nose?

The average dog brain is about one tenth the size of a human brain, however the part responsible for smell is around 40 times larger than it is in humans. They have WAY more scent receptors than we do. For every one scent receptor a human has, a dog has around 50. That wet nose actually assists your dog with their sniffing skills. This thin coating of mucus helps to capture scent particles as they draw in air. Dogs have been trained to use their noses in incredible ways, and can detect mines, drugs, explosives and even cancer.  Appreciating canine sniffing superpowers might inspire you to let them sniff just that little big longer on your next walk (they’ll love it!).
