Purpose: The paraprostatic cyst is a rare disease of the prostate gland in the intact male dog. This report de-scribes the physical examination, laboratory inspection, radiographic, ultrasonographic and computed tomo-graphic findings of the paraprostatic cyst in an intact male Belgian Malinois Military Working dog. Based on the previously reported research, this paper intended to verify that military working dogs can be diagnosed and treat-ed in the same way. Method: A 9-year-old intact male Belgian Malinois military working dog was presented for regular check-ups in the Department of Veterinary Medicine of the Armed Forces Medical Research Institute. Physical examinations, whole blood cell test, serum and electrolyte tests, radiography, abdominal ultrasonography and computed to-mography were conducted. Results: Using radiography, abdominal ultrasonography and computed tomography, a paraprostatic cyst was diagnosed. The dog underwent neutering surgery only. One month after the surgery, the dog was brought in for a follow-up. The previously observed large paraprostatic cyst was not evident in the area of the urinary bladder with ultrasonography. The treatment was deemed to have reduced the size of the cysts adjacent to the prostate as the prostate became smaller. Neutralization surgery was confirmed to be an effective treatment for diseases of the male genital system of aging dogs. It was also determined that male military dogs needed neutralization surgery at the age of six months, a positive stage, to prevent male genital disease. Conclusion: Unlike ordinary dogs, regular medical check-ups of military working dogs are recommended be-cause it is difficult to monitor their health. And neutering surgery at the time of disease diagnosis is recommended to treat and prevent the prostate-related disease for intact male dogs, especially for those beyond the age of six months.
