Acid Reflux in Dogs: A Helpful Guide

For anyone who’s ever eaten a hearty meal and felt that the food didn’t “settle” well, it may have been the symptoms of acid reflux and the accompanying heartburn that goes along with it. Just as that second helping of lasagna can lead to later regret for humans, dogs may also struggle with acid reflux and its side effects, though they have fewer ways of communicating that discomfort. 

A surprisingly common canine occurrence, acid reflux (the common terminology for ‘GERD’ or Gastroesophageal Reflux Disease) affects dogs of all breeds and ages, making it a persistent issue for a pet parent – not only does it have short-term, painful repercussions for your pup, but it can quietly cause long-term damage if left unchecked. In addition to being hard to notice, it can also be hard to diagnose during a normal vet visit. Therefore, a pet owner’s interactions with a beloved pooch will be his first line of defense against this troublesome, painful (but fortunately treatable) condition. 

Is Acid Reflux In Dogs Contagious?

With so many known illnesses that can pass between dogs, other dogs, animals, and humans, it’s prudent to be cautious when a dog is sick, particularly in a multi-pet household. The good news is that acid reflux in dogs is not contagious – it’s limited to the dog it afflicts, and cannot be passed through licking, playing with another dog, or sharing food and water. 

That said, if a pet pooch is diagnosed with acid reflux, it’s not a bad idea to examine his diet, from the occasional treat to the type of pet food brand he eats. While there are several reasons a dog can come down with reflux, diet can cause or aggravate symptoms very easily, which means another household dog could accidentally follow the same uncomfortable path.

Additionally, while it can be a particularly unpleasant possibility to consider, the other animals in a multi-pet household may also be causing your dog’s acid reflux. If an owner observes a dog spending a little too much time near the family cat’s litterbox, for example, the pup may be ingesting certain substances that are very unhealthy for his body and digestive system. Always isolate one animal’s waste from access to another pet to prevent this issue. Likewise, if a dog shares outside space with another animal – for example, a yard, a dog park, and so on – make sure waste is picked up in a timely fashion to prevent “curiosity.” This practice will also help combat the spread of other illnesses, such as canine parasites, that will happily travel from one afflicted dog to another through waste matter.

What Causes Acid Reflux In Dogs?

In addition to naturally-occurring acid reflux that crops up from age-related causes or in reaction to other illnesses, dogs can suffer from a canine hernia – a twist in the intestines that hinders the flow of acid or food – as well as congenital (i.e., from birth) causes. Ingesting a toxin or something harmful – think of an inquisitive pup accidentally drinking toilet water with a cleanser in it – can also cause acid reflux. The toxin or irritant is ingested and opens lesions or burns on the esophagus on the way down, stomach acid churns in an attempt to digest the harmful substance, and aggravates the new lesions in the process. This leads to a cycle of the same symptoms as the dog heals, and eventually leaves him with acid reflux long after the original irritant is gone. 

One of the most common causes of acid reflux is something far more common: diet. This means that pet parents have a lot of discretion in preventing the symptoms, particularly as the years pass with a four-legged friend. It sounds simple, but investing in a well-balanced, high-quality food is one of the best defenses against acid reflux for dogs. 

When a mass-produced kibble with artificial flavors, colors, and additives is used as a dog’s primary feed, it can be difficult to digest and may lead to churning stomach acid – and in turn, acid reflux. Even if pet folks decide to stick to a mass-produced kibble, it’s a good idea to supplement with “clean” food like boiled chicken breast or protein-rich wet food on a regular basis. This helps to balance his diet, and is a smart move for his nutrition too. While organic and all-natural or pricey, specially-formulated dog foods may not be in the budget, there are certainly whole food alternatives pet parents can cook at home for their beloved pets to ensure his diet is well-rounded – speak with a trusted vet for additional canine nutritional recommendations

Does My Dog Have Acid Reflux?

When a dog isn’t feeling well, it’s easy for worried fur-baby parents to vanish down the proverbial rabbit hole, mentally diagnosing them with dire, painful, and expensive ailments. The first step to healing acid reflux is to determine whether common symptoms have cropped up, and to take note of how often they occur. These include behaviors such as:

  • Whining or whimpering when eating, particularly when swallowing: If the dog in question doesn’t have obvious mouth sores or tooth decay issues, discomfort while swallowing signals a need for investigation. For concerned owners who are unsure and want to further test the theory, offer the dog wet or soft food and watch his behavior – if he’s not as vocal, that’s a strong indicator it may be acid reflux.

Why this happens: Acid reflux, even in minor cases, essentially opens lesions on the soft, vulnerable skin of the esophagus in dogs. When he eats, even if his food is well-chewed, this material is passing over these lesions and causing pain and discomfort with every bite. In addition to the rough texture of chewed kibble, acidic gravies can also cause problems, so make sure the “wet food test” is done with relatively neutral, bland canine food if possible. 


  • Lack of appetite or not finishing food completely: A loss of appetite in dogs is a less-precise flag over vocal discomfort, but it’s still very telling. Dogs stop eating for a variety of reasons, particularly if they’re ill, but acid reflux is definitely on the list. If a dog eats less but still seems interested in his food (and even reluctant to leave it), this behavior could indicate he’s simply suffering from a stomach acid-burned esophagus. 

Why this happens: Put simply – if a person’ throat hurt every time they ate, they would probably be reluctant to chow down, too. When a dog display the aforementioned behavior, he’s balancing his absolute minimum nutritional needs against his desire to avoid pain, and that may manifest as skipping meals or eating far less than he normally does. 


  • Vomiting or unproductive “dry-heaving”: Dogs vomit more readily than their human counterparts, but excessive vomiting, particularly routinely after eating, is a cause for concern. This is  even more true if the stomach upset appears to be a new symptom, and he previously kept his food in his stomach without issue. 

Why this happens: The stomach and the esophagus are separated in both dogs and humans by a sphincter muscle, an important part of the digestive system. When acid reflux weakens this pass-through, it affects its ability to keep stomach acid where it’s supposed to be, and some flows into the esophagus. Naturally, the dog’s body recognizes this isn’t ideal. His dog coughing and gagging are a reflexive attempt to clear the acid away from sensitive throat tissues, a problem that’s particularly aggressive after meals.

Vomiting can signal a “which came first” chicken-egg conundrum. While vomiting is a sign of existing acid reflux in a dog, it can also be a cause. If the dog in
