Damaicho Dog (detail introduction)
The canine caoped obstruction can be divided into three types: throat obstruction, neck esophageal obstruction, and chest esophageal obstruction according to the difference in the obstruction site. Dogs are mainly due to rapid swallowing, causing cavities obstruction, which is a more common symptom in the daily life of dogs.
Under the influence of the cause, the esophageal obstruction can occur in any part of the esophagus, but the dog often occurs at the entrance and bottom of the heart of the eesch's thoracic cavity. Due to the shape and size of the obstruction, the esophagus can be incomplete or completely obstructed. When there is incomplete obstruction, drinking water and fluid foods can also be swallowed, and the gas in the stomach can be discharged. When the esophagus is completely blocked, no food or drinking water can swallow, and the gas in the stomach cannot be discharged through the esophagus. Gas accumulated in the stomach will gradually increase, resulting in the increase of gastric volume. Due to the stimulation of obstruction, the muscles of the esophagus cause spasm contraction. The sick dogs are constantly showing swallowing movements, nervousness, and depression. The closer the obstruction is closer to the cardia, the stronger the spasm and contraction of the esophagus, the more obvious the tension of the sick dog, and the longer the duration. Due to the retrograde movement of the esophagus, the saliva accumulated in the esophagus will be discharged from the sick dog's mouth and nose, causing the expansion to temporarily disappear. Due to the effect of obstruction, a large amount of saliva cannot swallow inside the stomach, and stays in the upper part of the obstruction, and the neck canopy is significantly expanded. This reverse creep is distinctive in esophageal obstruction. It causes errors due to esophageal obstruction, which can cause foreign body pneumonia and cause death. If the obstruction cannot be removed in time, due to the oppression of the obstruction, it will cause varying degrees of breathing difficulties, which can seriously cause the diseased dog to suffocate and cause adverse consequences. At the same time, blocking the esophagus can cause inflammation, necrosis, perforation and other changes in the canine's esophageal mucosa.
