Dogs are highly social creatures. Sniffing is like “reading a profile” for them. Just as humans shake hands or greet each other verbally, dogs greet each other by smelling areas rich in scent.
When a dog sniffs your genital area, it may simply be doing a normal greeting. Dogs do this with:
-
New people
-
Family members
-
Visitors entering the home
-
People returning from outside
It helps them recognize who you are and how you feel.
Excitement or Attention-Seeking Behavior
Sometimes, the explanation is even simpler: your dog wants attention. When dogs notice that a certain action gets a big reaction—whether laughter, surprise, or embarrassment—they may repeat it.
If you laugh or push them away, your dog may think it’s a fun game.
Your Scent Carries Emotional Information
Dogs also use scent to understand your emotions. When you’re stressed, anxious, or nervous, your body releases different hormones like cortisol and adrenaline. Dogs can detect these changes.
So if your dog sniffs or nudges your groin area during stressful moments, it might be trying to check on you or comfort you. Some dogs even use this behavior as a way to offer emotional support.
When Is This Behavior a Concern?
In most cases, the behavior is totally normal. However, pay attention if:
-
The dog suddenly starts sniffing intensely more than usual
-
The dog seems fixated or worried
-
The dog behaves differently around you depending on your health
While dogs are not doctors, unusual interest can sometimes mean your scent has changed. If you notice other symptoms — unusual pain, swelling, discomfort, or changes in your health — you may want to consult a medical professional.
