Answer:
Esophagoscopy
Explanation:
According to my research on different veterinary procedures, I can say that based on the information provided within the question the veterinary is most likely to perform an Esophagoscopy. This is a procedure where the veterinary inserts a flexible endoscope in the mouth of the dog and guides it down to the esophagus. This device then takes enhanced images and displays it on a screen for the veterinary to see. This allows them to investigate and hopefully find the ulcer that is causing this problem.
