The different positions and movements of a dog's tail are referred to as dog tail language because they can carry significant communication information.

While a low, relaxing tail often denotes a peaceful or satisfied dog, a high, stiff tail frequently denotes alertness or dominance.

A dog's tucked tail, which is held between the knees, might be a sign of fear or submission.

While sluggish, wagging motions can show hesitation or caution, rapid tail wagging coupled with a relaxed posture may indicate enthusiasm or fun.

To correctly understand a dog's mood, it's critical to pay attention to their general body language, including their tail, in addition to other signs like their ears, eyes, and vocalisations.
