What is the purpose of a dog's tail base and how does it contribute to their overall communication and body language?

The purpose of a dog's tail base is to connect the tail to the body and provide support for movement. It also contains muscles that allow the dog to control the position and movement of its tail. The tail base plays a crucial role in a dog's communication and body language by allowing them to express emotions and intentions through the position and movement of their tail. For example, a wagging tail can indicate happiness or excitement, while a tucked tail can signal fear or submission.
