Why do dogs put their butts in other dogs faces?

Answer 1

Dogs great each other by sniffing each other. Your dog is just saying "hey, pleased to meet you, what's your name?". Female dogs will also do this as a flirting behavior especially if they are in season.

Answer 2

Dogs have thousands of olfactery sensors (far more than we do) in their noses that they use to get information about the world around them.

Close to the anus in dogs are glands that when smelled by other dogs tell them all sorts of information.

Dogs can tell another dogs gender, age, sexual maturity and interest, and dominance simply by smelling their rear end.

Think of it as a sort of introduction, the dogs meet, and then want to know where each other stand, who's dominate, who's submissive, who's ready to mate, etc.

Answer 3

Dogs use their sense of smell to communicate with each other, and one way they do this is by sniffing each other's behinds. They have special glands in that area that release pheromones which contain information about their identity and current state of mind. So when a dog puts its butt in another dog's face, it's a natural behavior for them to gather important information.

Answer 4

Dogs sense of smell is their strongest sense. They can remember dogs they have met by their smell. Basically it is their way of greeting each other and remembering who they are.

Answer 5

Answer 6
