Esophagitis (Inflammation of the Esophageal Mucosa) in Dogs
- Occurrence: common
- Location of illness: Chest
Esophagitis in dogs is an inflammatory condition of the esophageal mucosa that can be caused by various factors and leads to a variety of symptoms that can significantly impair the animal’s well-being.
The most important facts at a glance
Esophagitis in dogs is an inflammation of the esophageal mucosa that can be caused by various causes such as gastroesophageal reflux, foreign bodies, or infections. Gastroesophageal reflux, in which stomach acid flows back into the esophagus, is a common cause and can be exacerbated by a weakness of the lower esophageal sphincter or certain anesthetics. Symptoms include difficulty swallowing, Pain on swallowing, increased salivation, and regurgitation of undigested food. The diagnosis begins with a medical history and clinical examination, followed by an endoscopy for direct examination of the esophagus. X-rays or contrast studies can also be helpful. Treatment depends on the cause and severity of the condition and often includes dietary adjustments to relieve the esophagus. Medications such as antacids and proton pump inhibitors are used to control acid reflux. Antibiotics or antifungals are used for infections, while surgical procedures may be necessary for foreign bodies. The prognosis is usually good with early diagnosis and treatment, but chronic cases can lead to complications. Preventive measures include a balanced diet and avoiding irritating substances. Regular veterinary check-ups are important to identify problems early.
Causes
The esophagus is a muscular tube that transports food and liquids from the pharynx to the stomach. It is lined with a sensitive mucous membrane that can react with inflammation when irritated or damaged. This inflammation can be both acute and chronic and has different causes.
A common cause of esophagitis is gastroesophageal reflux, in which stomach acid flows back into the esophagus and damages the mucous membrane. This can be exacerbated by a weakness of the lower esophageal sphincter or by certain anesthetics. Another cause can be foreign bodies that get stuck in the esophagus and cause mechanical damage.
In addition, infections from bacteria or fungi can lead to inflammation of the esophagus. Certain medications that irritate the mucous membrane or burns from swallowing corrosive substances are also possible causes. Rarely, allergies or autoimmune diseases can also play a role.

The symptoms of esophagitis in dogs can vary depending on the severity of the inflammation and the underlying cause. A common symptom is regurgitation, in which undigested food or liquids flow back from the esophagus. This is often painless and occurs immediately after eating.
Other symptoms may include Vomiting, excessive salivation, difficulty on swallowing, loss of appetite, and Weight loss. Some dogs also show signs of Pain in the neck or chest area, which can be expressed through Restlessness or discomfort.
In severe cases, the inflammation can lead to a stricture, i.e., a narrowing of the esophagus, which can further worsen the symptoms. It is important to recognize these symptoms early to prevent them from getting worse.
Diagnosis
The diagnosis of esophagitis usually begins with a thorough history and clinical examination by the veterinarian. The owner is asked about the feeding history, the occurrence of symptoms, and possible triggers. A physical examination may reveal signs of pain or discomfort in the neck area.
To confirm the diagnosis, an endoscopy of the esophagus can be performed. A flexible instrument with a camera is inserted through the mouth into the esophagus to directly examine the mucous membrane for inflammation, injuries, or foreign bodies. This examination also allows tissue samples to be taken for a biopsy.
X-rays or a contrast study of the esophagus can also be helpful in identifying structural changes or foreign bodies. Blood tests can be performed to rule out infections or systemic diseases as the cause.
Therapy
The treatment of esophagitis depends on the cause and severity of the condition. An important part of the therapy is adjusting the feeding. It is recommended to offer small, frequent meals with soft or liquid food to reduce the mechanical stress on the esophagus.
Antacids or proton pump inhibitors can be used medicinally to reduce acid production in the stomach and control reflux. Prokinetics can help speed up gastric emptying and increase pressure on the lower esophageal sphincter.
Appropriate antibiotics or antifungals are prescribed for bacterial or fungal infections. In cases where foreign bodies or burns are the cause, surgical removal or endoscopic intervention may be necessary. Pain relievers and anti-inflammatory drugs can help relieve the symptoms.
Prognosis and follow-up care
The prognosis for dogs with esophagitis depends on the cause and severity of the condition. With early diagnosis and adequate treatment, the prognosis is usually good, and many dogs recover completely. However, chronic or untreated cases can lead to complications such as strictures or chronic inflammation.
Successful treatment often requires long-term adjustment of feeding and possibly permanent drug control of acid reflux. Regular follow-up with the veterinarian is important to monitor the progress of treatment and make adjustments.
Prevention
To prevent esophagitis, dogs should be fed a balanced and appropriate diet. It is important to choose feeds that are easily digestible and cannot cause mechanical injuries to the esophagus. Special feeding bowls can also be used preventively to prevent the swallowing of food.
Avoiding medications or substances that could irritate the esophagus is also crucial. In dogs with a known tendency to gastroesophageal reflux, prophylactic treatment with antacids can be considered. Regular veterinary check-ups help to identify and treat potential problems early.
Handling potentially dangerous or corrosive substances safely in the household is important to reduce the risk of burns. In addition, care should be taken to ensure that dogs cannot swallow foreign bodies that could get stuck in the esophagus.
