Surgical management of Cd1-Cd2 intervertebral disc extrusion in a dog.

Intervertebral disc disease involving the caudal vertebrae is an exceptionally rare condition in dogs. This report describes a rare case of intervertebral disc extrusion between the 1st and 2nd caudal vertebrae (Cd1-Cd2) of a beagle dog that was presented with severe pain associated with defecation and tail movement. Diagnostic imaging confirmed disc extrusion compressing the caudal spinal canal. Surgical decompression resulted in complete resolution of clinical signs. This report of the condition in a beagle dog adds to the literature that may suggest a breed predisposition. Key clinical message: Caudal intervertebral disc extrusion should be considered as a differential diagnosis for a dog that is presented with pain during defecation and tail movement. Early recognition and surgical decompression can result in complete resolution of clinical signs.
