Many dogs experience heartburn at some point in their lives. The underlying causes can vary widely, but an unsuitable diet is often a contributing factor. Heartburn is highly uncomfortable for the dog, and if it persists, it may lead to broader health issues. For this reason, prolonged symptoms should always be investigated together with a veterinarian. Occasional heartburn can sometimes be alleviated at home and supported with selected nutritional supplements.
A dog suffering from heartburn may show symptoms such as lip smacking, repeated swallowing, licking the lips, vomiting on an empty stomach, and behaviors like licking surfaces or eating grass. Grass contains a type of fiber called pectin, which dogs may instinctively seek to ease their discomfort. In some dogs, heartburn may also be accompanied by audible stomach gurgling.
Causes behind heartburn
The fundamental cause of heartburn, or reflux, is a dysfunction of the esophageal sphincter. In this situation, acidic digestive fluids intended for food processing may pass back through the lower esophageal sphincter into the esophagus, throat, and sometimes even the mouth. This results in a burning, stinging sensation in the esophageal area. In more severe or prolonged cases, it can lead to irritation or damage of the esophageal, pharyngeal, or oral mucosa.
Within the stomach, digestive fluids play an essential role in breaking down food. The stomach itself is protected by a thicker mucosal lining designed specifically to tolerate acidity. However, if acid-related problems persist, even the stomach’s protective mucosa may become compromised. This can increase susceptibility to further gastrointestinal disturbances.
Common contributing factors include digestive issues, unsuitable food, allergies or sensitivities, structural abnormalities, and stress. Certain medical conditions, such as kidney insufficiency, may also manifest with heartburn-like symptoms.
As a first step, heartburn can often be addressed through dietary adjustments. Dividing the daily food portion into several smaller meals may reduce reflux episodes. A systematic elimination approach—known as an elimination diet—can help identify ingredients that may be provoking symptoms. Highly seasoned or fatty foods are frequent triggers. For dogs prone to heartburn, keeping dietary fat levels moderate is advisable. Poorly digestible items, including real bones, should be avoided. Instead, offer easily digestible, stomach-friendly, low-fat foods to help control gastric acidity.
Managing symptoms
Heartburn symptoms may be supported with probiotic products, including lactic acid bacteria and digestive yeasts. Antacids may also be used to neutralize stomach acids. However, these solutions are not ideal for long-term use, as stomach acid is vital for normal digestive function. Natural alternatives traditionally regarded as supportive include ginger, slippery elm, licorice root, and marshmallow root.
Pectin supplementation
Pectin is widely used in managing acid-related issues in humans and horses. It has also been observed to benefit dogs prone to heartburn. Pectin can help buffer stomach acids, protect mucosal surfaces, and raise gastric pH. It is a water-soluble fiber naturally present in the cell walls of fruits and certain plants.
In acidic conditions, pectin forms a gel-like substance that helps stabilize stomach contents. Pectin also provides prebiotic benefits by supporting beneficial gut bacteria. Under acidic conditions, lecithin may break down into compounds that contribute to forming a water-repellent protective barrier between the stomach lining and gastric contents. This mechanism supports mucosal protection.
Protect That Tummy for dogs, developed by Chia de Gracia, contains pectin, lecithin, rosehip, brewer’s yeast, and clover seed flour. The pectin–lecithin combination helps coat the digestive tract lining and may enhance fat digestibility, which can indirectly help regulate acid production.
