This nursing care report discusses the treatment and management of acute hepatopathy and secondary coagulopathy in the canine as well as the impact this case had on the development of the author's nursing ability. The patient, a nine-year-old Labrador Retriever, was referred for treatment after an episode of vomiting followed by collapse during a walk with their owner. On presentation the patient was tachycardic, tachypnoeic with absent peripheral pulses. After haematological and biochemical analysis of the patient's blood, the clinical team implemented a medical care plan based on two differential diagnoses; xylitol poisoning or leptospirosis. The nursing team delivered an intensive care regimen including extensive patient monitoring, environmental modification, assisted feeding and blood transfusion with strict adherence to barrier nursing protocols. Fortunately, due to the dedicated efforts of the clinical team, the patient successfully recovered and was returned to their family in good health.
