To a dog, approaching this area is similar to how humans might introduce themselves with a handshake. It is simply an efficient way to gather information.
While people may view the behavior as inappropriate, dogs do not associate it with embarrassment or social discomfort.

Can Dogs Detect Changes in the Human Body?
Researchers have long studied dogs’ extraordinary sense of smell. Evidence suggests that dogs can sometimes notice subtle chemical changes associated with:
- Stress and anxiety
- Fear or excitement
- Hormonal fluctuations
- Pregnancy
- Certain illnesses and medical conditions
- Changes caused by medications
This doesn’t mean a dog can diagnose a disease simply by sniffing someone. However, unusual interest may occasionally be linked to scent changes that the animal finds different or noteworthy.
When Is the Behavior Normal?
In most cases, sniffing is completely normal canine behavior. Dogs are naturally curious and gather information through scent exploration.
