Genitals: their olfactory database
Contrary to appearances, this behavior is not a whim or a sign of bad manners. Intimate areas are particularly attractive to dogs because they contain apocrine glands, which emit pheromones. These chemical molecules contain essential data: emotional state, physical condition, stress level, and even hormonal status.
In canine language, this olfactory curiosity is equivalent to our way of exchanging pleasantries. Think of it as their version of “Hello, how are you?” or a welcome kiss.
