Thallium poisoning in a dog.

Abstract

A 10-year-old Lhasa Apso with a history of vomiting and hemorrhagic diarrhea of several hours' duration died despite emergency treatment. Necropsy revealed alimentary necrosis, and liver samples contained thallium at 7.6 ppm, indicative of thallium intoxication. The source of the thallium was not determined but was thought to be a rodenticide from a building being renovated. Recommended treatment includes use of diphenylthiocarbazone at 50-70 mg/kg every 8 hours PO, followed by ferric cyanoferrate at 100-200 mg/kg every 8 hours PO.
