Acid Reflux in Dogs

Acid reflux, a common but often overlooked condition, affects dogs just as it does humans. It’s crucial for pet owners to recognize this struggle, as it not only causes discomfort for our dogs but can also lead to more serious health issues if left untreated. 

This condition, where stomach acid flows back into the esophagus, can cause noticeable changes in a dog’s behavior and health. By gaining insight into what acid reflux is and how it manifests in dogs, pet owners can be better equipped to identify early signs and seek appropriate care. 

What Is Acid Reflux?

Acid reflux, also known as gastroesophageal reflux disease (GERD), occurs when the lower esophageal sphincter (LES), the valve between the stomach and esophagus, doesn’t function properly. 

This allows stomach contents to flow back into the esophagus. In dogs, this can be caused by a variety of factors. Dietary issues can trigger acid reflux, such as eating fatty foods. Similarly, irregular eating habits or consuming large meals can exacerbate the condition. 

Certain breeds, particularly brachycephalic dogs like Bulldogs and Pugs, are more prone to acid reflux due to their physical structure. Hiatal hernias, a condition where part of the stomach pushes into the chest cavity, can also contribute to acid reflux in dogs. 

Other factors include obesity, which increases abdominal pressure, pushing stomach contents upwards, and age-related changes in the digestive system.

How Does the Esophagus Function in Acid Reflux?

The esophagus is the conduit for food from the mouth to the stomach. The LES, located at the base of the esophagus, normally acts as a one-way valve to prevent backflow of stomach contents. 

In acid reflux, this sphincter malfunctions, allowing acidic stomach contents to flow back into the esophagus. This backflow, or regurgitation, can lead to irritation and damage to the esophageal lining, causing discomfort and potential health issues for the dog.

What Role Does Diet Play in Acid Reflux?

Diet plays a significant role in managing and preventing acid reflux in dogs. Foods high in fat can cause the LES to relax, worsening acid reflux. Additionally, acidic foods can irritate the lining of the esophagus. 

Feeding practices are equally important; overfeeding or feeding large meals can increase the likelihood of acid reflux, as a full stomach can put extra pressure on the LES. Incorporating smaller, more frequent meals can help reduce this risk. 

Low-fat, easily digestible foods are recommended to minimize the occurrence of acid reflux. Being mindful of a dog’s diet and feeding habits is a crucial step in managing this condition.

What Are the Common Symptoms of Acid Reflux in Dogs?

Identifying the symptoms of acid reflux in dogs is key to timely and effective treatment. Common signs include regurgitation, which is different from vomiting as it usually occurs shortly after eating and does not involve abdominal heaving. 

Dogs may also exhibit chronic vomiting, especially of undigested food. Also, pay attention to behavioral changes. Dogs with acid reflux may excessively lick their lips, burp, or swallow frequently, indicating discomfort. 

Bad breath can also be a telltale sign, stemming from the lingering stomach acid in the esophagus and mouth.

What Signs Suggest a Severe Case of Acid Reflux?

In severe cases of acid reflux, dogs may exhibit more distressing symptoms. These can include vomiting bile or intestinal fluids, a clear sign that the condition is affecting the lower sections of the digestive tract. 

Inflammation of the esophagus, known as esophagitis, can also occur, leading to pain, difficulty swallowing, and weight loss. If you notice these symptoms, seeking veterinary care is crucial as these indicate a more advanced stage of acid reflux.

What Are the Diagnosis and Testing Methods for Acid Reflux in Dogs?

It’s important to seek a diagnosis from your veterinarian. The process begins with a detailed review of your dog’s medical history and a physical examination. 

The vet may ask about your dog’s diet, eating habits, and specific symptoms. This initial assessment helps rule out other conditions that can mimic acid reflux symptoms, such as gastrointestinal disorders or pancreatitis.

Testing Methods 

To confirm a diagnosis of acid reflux, veterinarians may use several diagnostic tools. An endoscopy, which involves inserting a small camera into the esophagus, allows for direct visualization of the esophageal lining, helping to identify inflammation, ulcers, or any structural abnormalities. 

X-rays can also be useful, particularly in detecting hiatal hernias or abnormalities in the digestive tract. In some cases, a pH monitoring test may be conducted to measure the acidity levels in the esophagus.

Are There Other Diagnostic Considerations?

In diagnosing acid reflux, veterinarians also look at differential diagnoses. Conditions like foreign body ingestion, chronic vomiting due to other causes, or diseases affecting the digestive system may have similar symptoms. 

The vet needs to differentiate these conditions through appropriate tests to ensure accurate diagnosis and treatment. Advanced diagnostic methods, including blood tests and ultrasounds, may also be used to rule out other potential health issues.

What Are the Treatment Options for Acid Reflux in Dogs?


Diet plays a crucial role in managing acid reflux. Feeding your dog a low-fat diet can significantly reduce episodes of acid reflux, as high-fat foods can relax the lower esophageal sphincter, worsening the condition. 

Smaller, more frequent meals can help prevent the stomach from becoming too full, which can also trigger reflux. Additionally, choosing dog foods that are easily digestible can help. In some cases, a veterinarian may recommend specific dietary adjustments or specialized dog food formulated for digestive health.


Several medications can treat acid reflux. Antacids, like famotidine or omeprazole, are commonly used to reduce stomach acid production, minimizing irritation to the esophagus. Just remember not to give your dog human antacids, and follow your vet’s recommendation. 

Prokinetic drugs can sometimes be prescribed to strengthen the lower esophageal sphincter and improve gastrointestinal motility. 

Alternative Treatments 

Alternative treatments, including certain supplements, can aid in managing acid reflux. Probiotics and digestive enzymes may help improve gut health and digestion. 

Herbal remedies and supplements designed for gastrointestinal support can also be beneficial, but it’s crucial to consult a veterinarian before introducing any new supplements to ensure they are safe and appropriate for your dog.

How Can You Manage and Prevent Acid Reflux in Dogs?

While treating acid reflux is relatively straightforward, prevention is always the best course of action. 

Lifestyle Changes 

Implementing lifestyle changes can be an effective way to manage and prevent acid reflux. Helping your dog maintain a healthy weight will be important, as obesity can increase abdominal pressure and acid reflux. Regular exercise and appropriate feeding practices can also play a significant role in prevention.

What Regular Care Should Pet Owners Provide?

Regular veterinary check-ups are essential for monitoring your pup’s health, especially if they are prone to acid reflux. Keeping a diary of your dog’s eating habits, symptoms, and any episodes of reflux can help your veterinarian make informed decisions about management and treatment. 

Regular monitoring and adjustments to care as needed can help maintain your dog’s digestive health over time.

What Are Special Considerations in Treating Acid Reflux in Dogs?

While acid reflux can happen to any dog, there are certain considerations for a dog owner. Let’s look at a few. 

Breed-Specific Concerns

Certain breeds, especially brachycephalic dogs like Bulldogs and Pugs, are more prone to acid reflux due to their unique physical structure. These breeds require extra attention and may need different management strategies to control their.

Potential Complications

If left untreated, acid reflux can lead to more serious complications such as esophagitis (inflammation of the esophagus), ulcers, or even esophageal stricture. It’s important for pet owners to understand these risks and work closely with their veterinarian to prevent and manage these complications.

Wrapping Up

Acid reflux, a condition not uncommon in dogs, demands both awareness and action from conscientious pet owners. At ElleVet, we are committed to helping you recognize the symptoms early, and support your dog’s overall well-being every step of the way. 

We believe seeking veterinary guidance is the first crucial step toward addressing this digestive issue. Effective treatment often involves a combination of dietary management, appropriate medication, and lifestyle adjustments tailored to each dog’s specific needs.
