Zinc-induced hemolytic anemia in a dog caused by ingestion of a game-playing die

A 16-month-old spayed female mixed breed dog was presented with a 1-week history of anorexia, lethargy, diarrhea, vomiting, and difficulty rising. Hematologic evaluation indicated a marked macrocytic hypo-chromic, markedly regenerative anemia. A metallic foreign object in the gastrointestinal tract was identified on abdominal radiographs. Serum zinc concentration was markedly increased.
