Dog is a Crotch Sniffer – Pet tip 245

Most dog owners are aware that dog noses are extremely sensitive. This is due to the quantity of olfactory or ‘smell’ receptors in a dog’s nose. Whereas humans have around five million olfactory receptors, dogs have two hundred and twenty million. This makes their noses exponentially more sensitive than a human’s. Most times a dog’s sensitive nose works to our benefit. All kinds of dogs are used as service dogs to help humans find missing people, sniff out explosives, drugs etc. They can smell people coming from quite a distance and alert us to their presence. There are some embarrassing occasions however, when a dog’s nose is just too sensitive from our human perspective. Most notably this occurs when dogs try to sniff humans in their private areas.

This behaviour is a common one in dogs and equally common is the fact that it upsets most dog owners. The reason some dogs sniff at a human’s private parts is the same reason they sniff the private parts of other dogs. We know that when they smell other dogs in this way they can tell the sex, rank (is the dog more dominant or submissive) age and other information about the dog.
