Dopamine is a commonly used positive inotropic agent for the treatment of hypotension in small animals. Two dogs that had undergone surgery, under isoflurane anaesthesia, developed a sudden and profound bradycardia when a dopamine infusion was administered. Bradycardia was attributed to the activation of the Bezold‐Jarisch reflex, an inhibitory reflex, characterised by bradycardia and hypotension.
