Successful hemodialysis treatment of suspected acorn toxicosis in a Bedlington terrier.

A 17-month-old neutered male Bedlington terrier weighing 5.4 kg was presented because of vomiting, lethargy, and oliguria. Serum chemistry analysis revealed severe azotemia and ultrasonography revealed hyperechoic renal cortices. Acorn-induced acute kidney injury was suspected based on the animal's history of eating dried acorns over the previous 8 d. The dog did not respond to conventional intravenous fluid therapy, but his condition improved with intermittent hemodialysis. Although acorn intoxication is well documented in grazing animals, including cattle, it has rarely been reported in dogs. Acorns can cause acute kidney or liver injury, with high mortality rates. To the best of our knowledge, this is the first reported canine case of acorn toxicosis successfully treated with hemodialysis. The case findings indicate the importance of raising awareness among pet owners about the potential life-threatening effects of consuming acorns, particularly in regions where animals' exposure to acorns is likely. Key clinical message: Acorn ingestion can cause life-threatening acute kidney injury in dogs. Early recognition and timely intervention with hemodialysis can result in successful outcomes.
