In this episode, I speak to Dr Thomas Donnelly on how to apply advanced clinical reasoning to exotic species. We discuss the different types of clinical reasoning and how to effectively use the intuitive and analytical diagnostic approaches. We also talk through several medical scenarios where Dr Donnelly shows us how he effectively applies clinical reasoning to his exotic pet cases.
