A male neutered Staffordshire bull terrier presented for evaluation of urethral haemorrhage of three days duration. A urethral mass was identified on contrast radiography, ultrasonography and urethroscopy. An open excisional biopsy was performed and the mass appeared to arise from the vascular tissue beneath the urethral wall. Histopathology revealed evidence of ulceration and granulation; coupled with the clinical findings the mass appeared to be a herniation of corpus spongiosum through a defect in the urethral mucosa. Removal and closure of the urethral defect, along with postoperative propranolol, effected a clinical resolution. To the author's knowledge, a urethral mucosal defect as a cause of urethral haemorrhage has not been previously described in the dog.
