Perineal hernia (PH), or the failure of the pelvic diaphragm to support the rectum during defaecation leading to abnormal rectal faecal accumulation is a commonly presented clinical entity in small animal

practice. The underlying aetiology for this disease still remains unclear but older, male entire dogs predominate. PH requires surgical management and the prognosis correlates primarily with:

- Surgical technique selected

- Increasing experience with technique

The prognosis has not been shown to correlate with concurrent castration but discussion still surrounds the benefit of performing PH as a part of staged process to address concurrent disease (e.g.prostatic disease, bladder retroflexion).
