An average dog's nose is anywhere between 10,000 to 100,000 times more sensitive than ours, and smelling each others' butts is just another example of chemical communication in the animal kingdom.It's like speaking with chemicals, and that's how dogs ask about another dog's diet, gender, and emotional state.ogs also have a secondary olfactory system in their nose called the Jacboson's organ, which is designed specifically for chemical communication. Its nerves lead right to the brain -- so the smell of poop doesn't overpower their sensitive senses.
