Computed tomography‐dacryocystography (CT‐DCG) was used to evaluate the nasolacrimal system in four patients (three dogs and one horse) that were admitted for evaluation of chronic epiphora, facial swelling, or facial trauma. The four patients are reviewed and the technique for performing CT‐DCG is described. Additionally, the indications for this procedure are discussed. CT‐DCG is advantageous because cross‐sectional imaging provides superior resolution of the nasolacrimal apparatus and the relatively long, small‐diameter, bony nasolacrimal canal in most veterinary patients.
