The truth is that there’s actually a heap of good reasons why dogs stick their noses in… ahem, “private” places, dogs AND humans alike.

Mutual butt-sniffing is one of the first things that happens when two dogs meet. This may seem embarrassing or straight-up gross to us humans, but your dog sees it differently.

A dogs’ sense of smell is around 10,000 to 100,000 times better than humans. That’s generally why they can hear a bag of treats making their way out of the cupboard before you’ve even decided it’s treat time 😂

They also have a special part of their noses (called the Jacobson’s organ – weird, right?!) that lets them ignore the smell of poop when they sniff another dog’s butt. Instead, the organ detects something more important – the anal glands. These glands release chemicals which is what interests dogs the most about each other’s butts.

These chemicals tell dogs a lot about each other. They help a dog to know if another dog is male or female, how old it is, what it eats, how healthy it is, and even what kind of mood they’re in!

The chemicals also help it to know if other dogs are strangers or if they’ve met before. All of this helps dogs decide how they should behave. It’s how dogs first get to know each other! A butt sniff for dogs is like a handshake for humans.
