Highlight of the story: When you have ever been on a walk with your dog, you have no doubt seen that it spends rather more time sniffing the ground and lampposts and even loose leaves than actually walking. This sniffing continuously may seem to be a bother to most dog owners, but as a matter of fact, it is regular and a significant aspect of being a dog. This is the way dogs cognize the world around them through sniffing. Their olfactory sense is their main method of information gathering as human beings use their eyes. Thus, being able to explain why dogs smell all stuff on the ground makes us not only cherish their distinctive sense of smell more but also figure out what life is like with them.

The Power of a Dog’s Nose

The nose of a dog is marvelous in its smell. Humans possess an average of 5 million scent receptors located in the nose by contrast dogs have up to 300 million, although this may vary with the breed. It refers to the fact that dogs are able to smell at a concentration which is almost 100000 times less than that of humans. In other words, where we could just smell the slice of pizza, a dog can smell each single substance, cheese to oregano.
Their noses are snuff-boxes. A particular organ a dog possesses to help it in detecting pheromones was named the Jacobsen Organ or as sometimes referred to as vomeronasal organ. This enables them to gain access to chemical messages which relay information about other animals like mood, health and reproductive health.
