What is the significance of the dog’s tail according to JRTCA standards?

In the context of JRTCA standards, the tail of a Jack Russell Terrier holds significant value as it serves as an indicator of the dog's mood and overall demeanor. A tail that is carried high can suggest that the dog is alert, confident, and happy, while a tail held low or tucked away may indicate fear or submission. This aspect of the dog's tail signals to handlers and onlookers how the dog is feeling, making it an important component in assessing the dog's temperament during handling and training. Understanding this behavior can help handlers interpret their dog's body language more effectively, fostering better communication and a stronger bond between the dog and handler. The emphasis on the tail's position highlights the attention that should be paid to a dog's non-verbal cues in understanding their emotional state.
