What this symptom means clinically

Lordosis is a posture change in which the spine curves ventrally or forward, reflecting abnormal spinal structure, paraspinal muscle tone, or spinal cord or peripheral nerve function. This posture may reduce tension on a compressed area or compensate for hindlimb weakness, affecting weight distribution and gait. Persistent or progressive lordosis often suggests an underlying spinal or neurologic disorder.

🐱 In cats

Cats have flexible spines, so posture changes may be subtle. Lordosis in cats can be related to congenital spinal malformation or neuromuscular problems.

🐶 In dogs

In dogs, lordosis is often associated with spinal structural change, spinal cord compression, or hindlimb weakness, with cause and presentation varying by body size and breed.
