An 11‐month‐old intact male boxer cross was presented unconscious following oral heroin consumption. At home, intramuscular naloxone given by the owner showed no obvious improvements. Intravenous naloxone given in the hospital quickly reversed the clinical signs. The owners were not able to afford hospitalisation and the animal was discharged against medical advice. No signs of rebound opioid toxicity were reported. This case report describes the clinical presentation and treatment of a case of heroin intoxication in a dog.
