In tail jacking, lifting the tail aligns it with which part of the animal’s body?

In tail jacking, lifting the tail aligns it with the spine of the animal’s body. This technique is often used in veterinary practice or during handling to help control or restrain an animal. By aligning the tail with the spine, it allows for better management of the animal's posture, discouraging resistance and facilitating easier handling. This alignment helps maintain balance and stability in the animal, making it less inclined to struggle.

Other anatomical points, such as the head, leg, or shoulder, do not have the same stabilizing effect or control mechanism as the spine does in this context. Hence, aligning the tail with the spine is key to effective restraint techniques.
