To describe the use of extracorporeal therapy (ECT) in the management of a dog with complications stemming from heatstroke.A 3-year-old intact male Rhodesian Ridgeback was presented for heat-related illness following strenuous exercise. Despite intensive supportive care, the dog developed progressive and refractory hyperkalemia, hypoglycemia, neurologic dysfunction, acute kidney injury (AKI), and pulmonary dysfunction. Four ECT sessions were performed in this dog, consisting of 4 intermittent hemodialysis (HD) sessions, the first 2 of which concurrently utilized hemoperfusion with a cytokine adsorption filter. Interleukin-6 (IL-6), IL-8, IL-10, and monocyte chemoattractant protein-1 were detected in samples collected during the first ECT session. Despite an initial decrease in their concentration, the concentrations of these cytokines ultimately rose over the course of the ECT session. Rapid and sustained glycemic and electrolyte control were achieved after the first ECT session, although AKI and muscle injury persisted. The dog survived to discharge and was nonazotemic 3 months following initial management.Heatstroke is a common, potentially catastrophic, occurrence in dogs. To the authors' knowledge, this represents the first clinical use of ECT consisting of HD and cytokine adsorption in the management of severe heat-related illness in a dog. The use of ECT for the management of complications from severe heatstroke in dogs warrants further investigation.
