The paper describes a case of a dorsal type of perineal hernia in an 11-year-old bitch of the Yorkshire terrier breed. The hernia was situated between the levator ani muscle and the coccygeal muscle. The hernial sac contained small intestines and a small amount of the retroperitoneal fatty tissue. Additionally, both sided inguinal hernias and collapse of trachea were diagnosed in the dog. In the discussed case the perineal hernia was operated on by the means of placing sutures on the levator ani muscle and the coccygeal muscle. No recurrence of the problem was observed during 19 months following the surgery.
