==Description==
Rectal prolapse is defined as the protrusion of the rectal mucosa from the anus. It is classified as complete or incomplete. A complete prolapse involves all layers of the rectal wall whereas an incomplete prolapse only involves the mucosal layer.
Any conditions which cause tenesmus will cause rectal prolapse, this includes:
*Gastrointtestinal disese

Endoparasite and enteritis are more common in young animals whereas tumours or perineal hernias are more common in milddle-aged to older animals.
The everted tissue becomes oedematous, which prevents retraction back into the pelvic canal. The exposed tissue is vulnerable, which leads to inflammation, ulceration and congestion.
