A five-year-old, intact male, 31 kg, mixed breed dog was presented with progressive ataxic gait in the pelvic limb and reluctance to ambulate of one week duration. The thoracic vertebral region was severely painful on palpation. Pus at the tip of prepuce and perineal hernia were observed. Survey radiographs and computed tomography showed lysis of the endplates of T1-T2 and T5-T7 with irregular bony proliferations of the ventral aspect compatible with multiple discospondylitis. The enlarged prostate with multifocal hypoechoic cysts observed on ultrasonography was confirmed as a suppurative inflammation. Urine cultures yielded growth of Listeria monocytogenes and Escherichia coli. Three months after institution of treatment, the dog showed normal gait and sound general condition. This report shows diffuse discospondylitis related with cystitis and prostatic abscess.
