Pathology in Practice

HistoryA 2-year-old spayed female Greater Swiss Mountain Dog was evaluated because of a 1-to 2-month history of urinary incontinence and licking at the vulva.Treatment with phenylpropanolamine was partially successful, but some incontinence remained.The only known surgical procedure the dog had undergone was ovariohysterectomy at 6 months of age. Clinical and Gross FindingsPhysical examination revealed a possible mass in the caudal portion of the dog's abdomen.Important abnormalities were not detected via clinicopathologic analyses and urinalysis.Aerobic bacterial culture of a urine sample yielded no growth.Abdominal radiography revealed a mass located just cranial to the urinary bladder.
