Case Summary – An adult castrated male Australian cattle dog presented to an emergency clinic for an acute
onset of ataxia and disorientation after roaming a construction site unsupervised. He tested positive for ethylene
glycol using a point-of-care test kit. Treatment for ethylene glycol intoxication included intermittent intravenous
boluses of 20% ethanol and hemodialysis. Predialysis and postdialysis blood samples were submitted to the
toxicology lab to assess for both ethylene and propylene glycol. The patient tested negative for ethylene glycol
and positive for propylene glycol at 1100 mg/dL predialysis and 23 mg/dL postdialysis. The dog made a full
recovery.
