Abnormal dilation or stretching of the esophagus (also called megaesophagus) can be caused by a congenital defect, or it can occur in an adult dog, either alone or together with other diseases.
Patients affected by oropharyngeal dysphagia make exaggerated swallowing movements and food will usually drop from the mouth within seconds of prehension. In contrast, esophageal dysphagia results in more delayed regurgitation and is usually not associated with exaggerated swallowing movements.
Rarely there can be spontaneous inflammation, as seen with eosinophilic esophagitis in dogs. Brachycephalic dogs seem to have an increased incidence of gastroesophageal reflux, esophagitis, and perhaps hiatal hernia. Finally, esophageal foreign bodies typically cause varying degrees of esophagitis.
8 lis 2023 · Difficulty swallowing in dogs, known as dysphagia, is a common symptom with many different underlying triggers. Dysphagia involves either disruption of the nerve signals involved with swallowing, physical disruption of the nerves and muscles, or pain.
