Rectal Prolapse

Rectal prolapse tends to appear most frequently in young animals—particularly puppies and kittens under six months of age—whose supporting tissues may be less mature and more susceptible to displacement under strain. It can also occur in older animals with chronic gastrointestinal conditions, parasitic infections, or any disease process that triggers repeated episodes of diarrhoea or constipation. Certain breeds with a predisposition to bowel disorders or anatomical variations in pelvic structure may experience prolapse more often, though no breed is entirely exempt. Seasonal patterns sometimes emerge when parasitic loads increase or when dietary changes during weaning introduce digestive upset.

The prolapse may initially appear as a small, intermittent protrusion that retracts on its own once the triggering episode of straining has passed. In some individuals, the tissue begins to emerge more frequently or remains outside for longer periods, particularly if the underlying cause—such as ongoing diarrhoea or urinary straining—continues unchecked. Over time, tissue that remains prolapsed can become swollen, congested, or damaged by exposure and contact with the environment, which may in turn make spontaneous retraction less likely. The pace of progression varies widely: some animals experience a single brief episode that resolves, while others develop a persistent or recurrent pattern.
