If your dog sniffs your genital area, it’s natural instinct. Dogs rely on smell more than sight or hearing and can detect chemical signals called pheromones, which convey information about identity, gender, health, and emotional state. Sniffing is often a greeting or a way to gather information, not a sign of bad behavior.
While normal, it can feel awkward for humans. Training, redirection, and consistency help manage excessive sniffing. Rarely, compulsive sniffing may signal stress, anxiety, or medical issues, so consult a vet if it seems abnormal.
In short, genital sniffing is a typical, instinct-driven behavior, usually harmless, and manageable with guidance.
