Humans have around 6 Million of these receptors, dogs have up to 300 million of these receptors, scientists still do not know how all these extra receptors affect the dogs but are beginning to search for some answers. So next time you are out for a walk with your dog and is sniffing around give him that extra five seconds of sniff.
