Why do dogs sniff each other’s butts?

To fully understand why dogs smell each others butts, we first need to be aware that a dog’s way of communicating with humans is very different to a dog communicating with another of the same species. Dogs use smell, sound, facial expression and body language as their main pillars of communication.

Many dog behaviors which we may at first perceive as strange, are normal for dogs. For example, while dogs sniffing each other’s butts may seem bizarre to us as humans, for dogs this is a normal way of communicating and exchanging information. When it comes to canine social behavior, butt sniffing is a way of learning about mood, gender and functions as a way of saying ‘hi!’

Did you know that dogs have a special scent-detecting organ which we as humans don’t have. The vomeronasal organ in dogs allows dogs the ability to detect pheromones in other dogs. Not only does this play an important part when it comes to canine reproduction, but it also helps dogs understand each other better.

Dogs carry up to 300 million olfactory receptors in their noses, while we humans only carry around 6 million. This is why dogs can smell hormones and non-volatile chemicals produced and secreted by glands of other bodies, such as dogs, cats and humans.

When two or more dogs meet and voluntarily decide to raise their tails and smell each other’s butts, they are carrying out a key step canine social behavior. This means that both dogs are interacting positively and have decided to openly exchange their "personal data," thereby establishing a cordial bond.

Why do dogs sniff bums?

When dogs smell another dog’s anus, they establish a kind of "chemical communication" that allows them to collect data about age, gender, immune status, mood, diet and genetic inheritance. This is possible because dogs have anal or perianal glands which secrete a concentration of all their chemical information and/or canine identity. Therefore, it is common to hear that a dog's "fragrant signature" is found in its bum.

Additionally, as we mentioned before, dogs also have a highly developed olfactory system. When sniffing near the anal glands, two or more dogs can interact chemically. Thus, anal glands and smell play a key role canine communication and social behavior. This is why you should never reprimand or punish your dog when they smell another dog’s bum.

It is also interesting to mention that a dogs have an incredibly olfactory memory, offering them the ability to remember characteristic odors of other dogs, people and animals (for an extended period of time). For this reason, you may notice that your dog may interact normally with dogs or people they have met before, because they technically already ‘‘know’’ each other.
