What condition is characterized by a distinct fall or scoop in the back between the shoulders and hindquarters?

The condition identified as sway back is characterized by a noticeable dip or scoop in the back of the rabbit, specifically between the shoulder area and the hindquarters. This physical trait is typically recognized by the way the spine curves downward rather than maintaining a straight or level line, which can be a sign of poor breeding practices or health issues in rabbits. A sway back can affect the rabbit's overall appearance and movement, reflecting an underlying concern that may need to be addressed by breeders or caretakers.

In contrast, tail carriage refers to the positioning of a rabbit's tail and does not involve the spinal structure. Ticking describes a coat pattern involving color variations in the fur, which is unrelated to the shape of the back. Symmetry pertains to the overall balance and proportions of the rabbit's body rather than specific structural issues in the spine. Hence, sway back is the direct answer to the question regarding the physical condition of the rabbit's back.
