An eight year old, female spayed mixed breed dog presented to a local emergency clinic with a three day history of lethargy, vomiting and anorexia. The owners reported they found two United States pennies dated 1989 and 1999 in her vomitus. Basic diagnostic tests and supportive therapy were administered and the patient referred to the Cornell University Hospital for Animals (CUHA). The patient was admitted to the CUHA Intensive Care Unit where additional diagnostic tests were evaluated and she received more extensive therapy. Hemolytic anemia secondary to zinc intoxication was confirmed. After 8 days of hospitalization the patient was discharged and subsequently made a complete recovery.
