Research output: Contribution to journalArticlepeer-review


Thallotoxicosis is described in an adult Pit Bull Terrier. The dog exhibited anorexia, emesis, weakness, conscious proprioceptive deficits, and a hemorrhagic diarrhea before death. A severe, acute necrotizing enterocolitis was evident upon histological examination, as was a multifocal to coalescing pulmonary edema. Liver and kidney thallium concentrations were 18 and 26 ppm, respectively. The source of the thallium was determined to be thallium sulfate obtained by a person with the intent to harm family members. Although thallium has not been produced in the United States for 20 years, this report demonstrates the need to consider thallium toxicosis as a differential diagnosis for animals presenting with vague and mixed gastrointestinal and neurological signs.
