Epiglottic retroversion—a rare, poorly understood condition in dogs—occurs when the epiglottis is episodically retroflexed into the rima glottidis, causing airway obstruction. This case report described the management of epiglottic retroversion. The patient was presented with clinical signs associated with upper airway obstruction. Multiple surgical strategies were attempted; all failed. Ultimately, subtotal epiglottectomy across the widest base of the epiglottis was performed, with resolution of clinical signs through 17 months postoperatively.
