Dog Acid Reflux: Is There A Natural Antacid For Dogs?

Is your pup suffering with a painful upset stomach? From a lack of appetite to bouts of regurgitation, we understand the challenges that come with dog acid reflux. Our specially formulated probiotics, digestive enzymes, and natural antacid for dogs provide fast relief from acid reflux, heartburn, and GERD.

Ask Ariel's proven approach to treating acid reflux in dogs naturally involves two steps. The first step is to implement dietary changes by eliminating potential trigger foods and opting for easily digestible food choices. The second step is to incorporate home remedies specifically designed to treat acid reflux in dogs.

What Is Acid Reflux in Dogs?

Dogs can get acid reflux, acid stomach, gastroesophageal reflux disease (GERD), heartburn, and other similar conditions just like people. Gastroesophageal reflux disease (GERD) - or acid reflux - is the backflow of stomach acid and intestinal fluids into the dog’s esophagus. Over time, the fluids can damage the lining of the esophagus, causing inflammation and discomfort.

Causes of Acid Reflux in Dogs

There are a range of causes for acid reflux in dogs, but most instances of acid reflux, heartburn, or symptoms of GERD stem from your dog’s diet and digestive health.

Some common causes of dog acid reflux include:

  • Poor digestion
  • Poor diet
  • Food intolerances
  • Allergies
  • Hypochlorhydria (low stomach acid)
  • Intestinal dysbiosis
  • Bowel disorders

Symptoms & Signs That Your Dog Has Acid Reflux

Acid reflux and GERD in dogs (and cats) can be very uncomfortable and painful. Common dog acid reflux symptoms include:

  • Lack of appetite, especially in the morning
  • Vomiting of bile
  • Regurgitating undigested food shortly after being consumed
  • Excessive grass eating (some grazing on grass is normal)
  • Gulping or loud gurgling noises
  • Licking or smacking of the lips
  • Panting a few hours after meals
  • Lick Fits (frantic licking of floors, walls, grass, dirt)

Diagnosing Acid Reflux in Dogs

To diagnose acid reflux or GERD in dogs, veterinarians typically examine the pet and conduct laboratory tests (various GI studies, blood and urine) along with imaging (x-ray and ultrasound). In some cases, an endoscopy may be recommended. This involves a scope being used to examine your dog's esophagus for inflammation. A dog endoscopy requires anesthesia and can be costly, leading many pet owners to explore more affordable and less invasive treatments before obtaining an official diagnosis.

Dog Regurgitation vs. Vomiting

Regurgitation in dogs is when undigested food or water comes up from the esophagus. Dogs may just be walking and soupy food falls out of their mouth. Regurgitation can be a symptom of acid reflux in dogs.

Dogs with acid reflux often have dysbiosis - an imbalance in gut bacteria. This imbalance weakens the lower esophageal sphincter (the muscle separating the esophagus and stomach), allowing stomach contents to flow back into the esophagus. To prevent regurgitation in dogs, it's crucial to maintain a healthy microbiome through proper nutrition and address dysbiosis.

Vomiting may also be a symptom of acid reflux, but it differs from regurgitation. Regurgitation occurs in the esophagus, typically due to issues with esophageal function. Vomiting involves the stomach and is associated with abdominal contractions and the forceful expulsion of stomach contents. Both regurgitation and vomiting are uncomfortable and painful symptoms associated with dog acid reflux.

What to Do About Dog Acid Reflux at Night

Acid reflux in dogs can cause discomfort, irritation, and a burning sensation in the esophagus due to the backflow of stomach acid. This discomfort may lead to symptoms such as regurgitation, vomiting, restlessness and swallowing noises. Here are some reasons why acid reflux in dogs might be more noticeable or problematic at night:

  • Lying Down: When a dog lies down the stomach contents are more likely to reflux into the esophagus.
  • Decreased Salivation: Saliva helps neutralize stomach acid and dogs produce less saliva during sleep. Reduced saliva production at night may contribute to increased acidity.
  • Increased Pressure: In a lying position, there is less gravitational assistance in keeping stomach contents down, allowing acid to move more easily into the esophagus.

Feeding a small, easily digestible snack at bedtime is an easy dog acid reflux at night treatment. An empty stomach may produce more stomach acid, so feeding a small snack ensures that your dog doesn't go to bed on an empty stomach. Some foods may act as natural antacids, helping to buffer stomach acid and reduce the likelihood of reflux. For example, a small amount of raw goat milk for dogs can have a soothing effect.

Dog Acid Reflux Testimonials


"When we got our rescue dog, Roo, he was very underweight and had little interest in eating. He had chronic diarrhea, would gag after drinking and was regurgitating small amounts of food.

We started Roo on Soothing Digestive Relief, Power Probiotic and NOT Drops initially. That helped his diarrhea and tummy gurgling. He also started to show more interest in food, but he continued to regurgitate. We introduced the K9 Digestive Enzymes with HCL and the regurgitation stopped. Roo has gained 7 pounds and is now a normal weight.

We can’t express our gratitude enough about how much these supplements have changed his life." - The Davis Family, California


"I want to let you know how great Dakota, our Golden Retriever that we rescued, is doing. When we got him, he had bad ear infections that he had for months, and his skin was so black in the armpit and groin areas that we thought it was ground in dirt. He also had acid reflux and would bring up bile several times a day. It has taken several months, but the blackened skin (from yeast) is almost back to normal thanks to K9 Yeast Defense. I wish we had taken “before” pictures of his skin because the difference is remarkable. And, for his acid reflux, we started using your supplements (Power Probiotic, K9 Digestive Enzymes, Gastro ULC and Soothing Digestive Relief). We used to give him Pepcid, but we have been able to slowly wean him off. I can’t forget to mention using your food recommendations. Thank you so much for your supplements and all your help. Dakota is a much happier dog thanks to you!" - Pat & Tim, Pennsylvania


"My 9 year old Welsh Springer Spaniel mix, Max, didn't have much of an appetite and would frequently vomit. He would often rush out to eat grass and then vomit afterwards. I was worried because he was thin and seemed so uncomfortable. I wanted to find a natural alternative to Pepcid for dogs. I followed the Ask Ariel program and changed his diet while using supplements such as Gastro ULC and Power Probiotic. I really wasn't expecting much because I had made prior changes before that hadn’t worked. Within just a few days, Max improved. He no longer was interested in eating grass and his vomiting stopped. Max is now at a healthy weight and it is so nice to see him so happy to see his meals." - Karen, California

Pretty Boy

"I'm writing to tell you that with the help of your supplements, my dog Pretty Boy just turned 17! About four years ago, Pretty Boy started experiencing a chronic cough. At the time, he was taking supplements from another company. He was diagnosed with heart disease and put on conventional medication. I continued with the supplements previously mentioned but I wasn't satisfied with the quality so I decided to search for another source. That's when I found Ask Ariel. Pretty Boy is taking Power Probiotic, Amazing Omegas, Gastro ULC, LypoZyme, Soothing Digestive Relief (when necessary) Dog Brain Booster, Kidney Health, Renelix, Purrfect Pet COQ10, along with his conventional medications to address his heart condition, kidney disease and chronic pancreatitis. Although this seems like a lot of supplements, the combination (with my holistic vet's approval) works well for him and keeps him full of energy. The supplements are all very high quality and with patience and time, really do work. My favorite is the Gastro ULC. Within a couple of weeks, I was able to wean him off of his twice daily administration of Pepcid for his acid stomach due to kidney disease. His digestive woes have all been diminished with the addition of the LypoZyme and Power Probiotic. Thank you for always taking the time to answer my many emails. My resilient little man means the world to me and I am willing to do whatever it takes to keep him healthy and happy!"

What To Feed A Dog With Acid Reflux?

Dogs who suffer from acid reflux or GERD frequently see an improvement in symptoms by eating a high moisture, low carbohydrate, hypoallergenic diet. Look for food options containing real meat or fish as a first ingredient. Eliminating common allergens, such as beef, poultry or grains, can be helpful for many dogs with acid stomach. Chemical ingredients like preservatives, colorings, and additives provide no nutritional value and can also contribute to a dog upset stomach.

Please include your dog's diet and treats on the order form at checkout. At Ask Ariel, we include FREE diet tips for dogs with acid reflux with each order.

Can I Give My Dog Milk For Acid Reflux?

Some dogs may be allergic to casein, the protein found in milk. This can result in symptoms like diarrhea, gas, and abdominal discomfort.

Small amounts of raw goat milk made for pets contains probiotics that can promote a healthy balance of gut bacteria, which might help with digestion. For dogs that have acid reflux in the morning and are reluctant to eat, raw goat milk may be a safe and soothing option.

Feed Smaller, More Frequent Meals

To alleviate acid reflux in dogs, feeding them multiple small meals throughout the day is recommended. Maintaining a consistent feeding schedule is also helpful. A small snack at bedtime, such as raw freeze-dried food or a small amount of goat milk, is an effective dog acid reflux at night treatment.

Acid Reflux & GERD Frequently Asked Questions (FAQs)

Is there a natural antacid for dogs and cats?

Poor digestion, food allergies and low quality ingredients in pet food contribute to acid reflux. You can help relieve painful acid stomach by using a few natural home remedies along with changing your pet’s diet. Our comprehensive natural antacid treatment for dogs and cats includes a home remedy for acid stomach; along with digestive enzymes, probiotics and free diet tips to improve your pet’s digestion. Ask Ariel’s natural antacid for dogs and cats contains licorice root extract and L-Glutamine to protect the mucous membranes against bacteria, like H.Pylori, and helps to soothe and repair the stomach lining. It also contains mastic gum to relieve inflammation and discomfort.

What can I give my dog for acid reflux?

Dogs with acid reflux show signs such as vomiting bile, excessive grass eating, panting or gulping at night. You may also hear loud, digestive noises coming from your dog’s stomach. Acid reflux in dogs occurs when stomach acid pushes up out of the stomach and into the esophagus, causing pain, heartburn and discomfort. Antacid medications are prescribed, such as omeprazole, to prevent acid production, but they can interfere with proper digestion and contribute to intestinal dysbiosis and SIBO. If acid levels are too low, the stomach cannot fully digest food. Digestive enzymes containing hydrochloric acid (HCL), pancreatin and ox bile extract can aid in the breakdown and absorption of fats and proteins. Gas, burping and heartburn are symptoms of poor digestion. Feeding a low carbohydrate, grain-free diet combined with digestive enzymes and our natural stomach acid reducer for dogs can optimize digestion and relieve the pain and inflammation caused by stomach acid.

What are natural remedies for acid reflux in cats?

How do you know if your cat has acid reflux? Watch for signs such as loss of appetite, weight loss, vomiting or spitting up food. Cats can develop acid reflux due to poor digestion, food intolerances, IBD and health conditions such as kidney disease. When cats have acid reflux, the stomach produces too much acid and it comes up into the stomach and esophagus. Most cats will cough and vomit…even yellow or foamy bile. Cats can be very finicky so it’s important to use a tasteless digestive enzyme containing a proprietary blend of lipase, protease and amylase. Probiotics, Ask Ariel’s natural antacid for cats and diet changes can help.

How do you treat GERD in dogs?

Gastroesophageal reflux (GERD) is another name for acid reflux, a condition where gastric fluid flows backward into the esophagus. Dogs with GERD may vomit, cough, eat grass, gulp, lick their lips and burp. It can be very uncomfortable, but a few natural remedies can help soothe and repair the throat, tummy and intestinal tract. A powerful probiotic can help to balance the good and bad bacteria in your dog’s microbiome and help to improve appetite by calming the burn caused by stomach acid. GERD is caused by poor digestion, so it is essential to use a digestive enzyme to improve your dog’s digestion of fats and proteins. A natural stomach acid reducer can also help to relieve stomach acid pain and repair inflamed tissue. Diet changes, such as avoiding dry kibble which can cause bloat, can also help.
