Human crotches contain pheromones, which are chemicals that communicate information about a person, such as their age, sex, and health. Dogs can detect these pheromones and use them to learn about the people they meet.
Smelling crotches is also a way for dogs to greet each other. Dogs exchange information about themselves and their health by sniffing each other's genitals.
Dogs are curious creatures and love to explore their surroundings. Smelling crotches is just one way that dogs learn about the world around them.
Some dogs may smell crotches as a way to assert their dominance. This is more common in male dogs than in female dogs.
Dogs can also smell crotches to check for signs of illness or injury. If a person is sick or injured, their body may release different pheromones that dogs can detect.
So, why do dogs smell crotches? It's a combination of factors, including pheromones, greeting, curiosity, dominance, and health. If your dog likes to smell crotches, don't worry. It's just being a dog.
If you don't like your dog sniffing your crotch, there are a few things you can do to stop them. First, try to train them to sit or stay when you greet them.
