Rectal Prolapse

Rectal prolapse describes a situation in which part of the lining of the rectum protrudes through the anus, appearing as a visible, often cylindrical or rounded mass of pink or red tissue. It can occur as an isolated event or develop gradually, and tends to be associated with conditions that cause repeated straining—such as ongoing diarrhoea, constipation, or certain urinary or reproductive problems. Owners most often notice a fleshy tissue emerging from the back passage, which may appear after defaecation or straining, and in some cases may retract on its own or remain visible. The tissue can become swollen, darker in colour, or dry if it stays outside for a period of time. Young animals and those with chronic bowel issues are more commonly affected, though it can appear at any age. This page explores what owners may observe at home, what processes underneath tend to contribute to prolapse, how the condition is assessed, and what approaches exist for managing both the immediate presentation and any underlying cause.
