(Dyssynchrony - failure to open at appropriate time; achalasia - failure to open fully)
You take radiographs on an anesthetized dog after thoracic surgery and notice their esophagus is dilated, what do you want to do next?
(Wake them up and take awake radiographs → if normal = nonpathologic esophageal dilation d/t anesthesia drugs)

(No)
