Abstract
Peritoneal dialysis was used to assist the recovery of a dog from acute ischaemic renal failure secondary to dehydration. Although time consuming and requiring strict attention to asepsis, peritoneal dialysis is well suited to veterinary practice as equipment cost is minimal. Of interest in this case was the development of two intussusceptions during treatment This has not been previously reported in association with peritoneal dialysis, but has been linked to renal transplants. The dog recovered with only mild non-progressive renal insufficiency.
