Intervertebral Disc Disease (IVDD) – Anatomical Factors Contributing to Disc Herniation in Dogs

Introduction

The spinal column is designed to provide both stability and flexibility. At its core, the intervertebral disc acts as a resilient cushion, allowing movement while protecting the delicate spinal cord. Each disc comprises two primary anatomical components: the central nucleus pulposus, a gelatinous core, and the surrounding annulus fibrosus, a tough, fibrous outer ring. This intricate design is inherently susceptible to degeneration and subsequent herniation, particularly under specific anatomical and genetic predispositions.
