This exchange of personal information can help dogs build identification and trust with each other.

In addition, sniffing the butt can also convey a dog's mood and state. The glands in the dog's butt also secrete a special scent that can communicate the dog's mood and state.

This communication of emotions and states can help dogs better understand and adapt to each other.
