Why Do Boxers Lick The Air? It Could Be Acid Reflux

An often overlooked cause of air licking in Boxers is acid reflux, also known as gastroesophageal reflux disease (GERD).

Your Boxer may appear to compulsively lick the air or keep constantly swallowing, often accompanied by an array of other symptoms — some clearly indicative of stomach upset and others harder to make sense of.

Attacks can happen regularly or only once in a while.

They might last anywhere from a few minutes, to 24 hours straight.

This post is for general informational and educational purposes only. I encourage readers to see my full disclaimer here.

What Is Acid Reflux?

Acid reflux is when gastric juices escape the stomach and flow back into the esophagus, or food pipe.

These gastointestinal fluids can include bile, pepsin and stomach acid.

Not surprisingly, they irritate the esophageal tissue and cause discomfort. In humans acid reflux is often described as a burning sensation.

Symptoms Of Acid Reflux In Boxers

As well as air licking, Boxers with acid reflux commonly display several other symptoms and behaviors including:

  • Drooling (a sign of nausea in dogs)
  • Jaw Snapping (like your dog is trying to catch flies)
  • Licking own fur or fabric of bedding etc
  • Trying to eat leaves or specks of dust off the floor
  • Neck stretching
  • Gagging
  • Constantly swallowing, loud swallowing or gulping
  • Restlessness
  • Throat gurgling
  • Harsh coughing
  • Dry retching
  • Sometimes vomiting (either food or clear fluid)

What Causes Acid Reflux In Boxer Dogs?

The usual veterinary explanations for acid reflux encompass a broad range of mechanisms such as:

  • Too much stomach acid
  • Too little stomach acid (hypochlorhydria)
  • Poor tone or improper closure of the lower esophageal sphincter that controls the opening between the esophagus and the stomach
  • Slow stomach emptying

Surgery can also cause acid reflux in dogs.

But, leaving aside the surgical scenario, why do these problems develop in the first place?

Vets don’t really know.

Many dogs develop acid reflux after:

  • A course of medication like the steroid prednisone or antibiotics
  • Being kibble fed for a considerable length of time (Here are some of the ways kibble can damage your dog)
  • Eating commercial dog food that is high in fat (which is virtually all dog food, notwithstanding misleading labelling that lists fat content by weight instead of by calorie, yielding a lower number)

Antibiotics and steroids like prednisone are known to damage the microbiome in the gut and they also seem to affect the upper digestive tract.

Acid reflux can first present at the point of discontinuing medication or improving the diet (from kibble to raw, for instance).

In this case the reflux can be understood as part of a detox event, as a cleansing process sees long-stored toxins exit the body, including via the digestive tract.

These toxins can irritate tissues, creating the symptoms of acid reflux.

How Not To Treat A Boxer From Acid Reflux

Veterinary responses to acid reflux typically involve prescribing Pepcid (Famotidine) which is a histamine-2 blocker that decreases stomach acid.

The proton pump inhibitor Omeprazole (Prilosec) is another commonly given drug, also aimed at reducing stomach acid.

Prolonged use of these drugs carries considerable health risks to your dog.

Sometimes vets recommend a drug such as Metoclopramide, designed to address delayed stomach emptying by improving stomach “motility”.

Drugs often appear to work for a short time.

But medicating for acid reflux does not address the underlying cause of the dysfunction and so symptoms usually return.

Owners frequently become stuck on a merry-go-round of drugs and are sold exploratory surgeries and other diagnostic procedures.

“Prescription” diets are another trap.

Check the label — these are not ingredients conducive to healing.

These products are highly processed and bear no resemblance to a dog’s natural diet.

How To Heal Acid Reflux In A Boxer Dog

The experience of owners with dogs suffering acid reflux is sad testament to the fact that a lasting solution to the condition can’t be bought in a bottle.

Likewise, home remedies for acid reflux in dogs including slippery elm bark powder and yoghurt may initially offer some relief, but rarely does it last.

Rather, healing acid reflux requires a more holistic approach that addresses the problem at its source, instead of simply suppressing symptoms.

While the medical model conditions us to ask “What can I add?”, owners typically have much more success by removing cause and setting in place the conditions for optimal health.

In this way, the body’s in-built detoxification processes are supported, and gut repair and regeneration promoted.

Acid reflux can be healed without drugs using a combination of:

  • Feeding a fresh, natural canine diet (i.e. a raw meaty bone-based diet)
  • Identifying and eliminating toxic exposures e.g. chemical wormers, drugs, vaccines etc
  • Fasting

Feeding a fresh, biologically-appropriate diet is step one to healing any health problem, as is minimizing the toxic load on the body, which is a recognized cause of aging and disease.


  • Triggers a process known as autophagy during which the body undertakes repair and regeneration at a cellular level
  • Provides digestive rest, allowing energy usually expended on digestion to be diverted to healing
  • Boosts liver detoxification pathways, accelerating the removal of toxins from the body

For all these reasons, fasting is a powerful healing modality employed by holistic vets, though not often within the repertoire of conventionally-trained ones.

Fasting is:

  • Side effect free compared to pharmaceutical interventions
  • How dogs respond to, and recover from illness in the wild
  • Supported by an increasing body of scientific evidence

Fasting is particularly important when the issue to be healed is a digestive one.

Be sure to always have fresh, pure water available during fasting. (Not tap water. Here’s why.)

Unfortunately, the highly disruptive nature of acid reflux as a condition, and the distress of witnessing a dog suffering repeated attacks, often prompts owners to resort to medicating their dogs.

This increases toxic load on the body, fails to address cause and derails the healing process that is possible with patience, time and proper feeding.

How Long Does It Take To Heal Acid Reflux?

Gut epithelial cells are replaced on average once every five to seven days, a regenerative capacity that is conducive to the healing of GI disorders.

However, acid reflux takes time to develop. Similarly, healing can take months and years with a gradually decreasing frequency and severity of attacks.

Persistence is key as symptoms can appear to get worse for a time, before they get better.

How To Prevent Acid Reflux Attacks From Starting

While you are working on healing your dog’s acid reflux, you can help minimize the number of attacks by taking steps to make digestion as efficient as possible.

You can:

  • Feed smaller meals (smaller meals are easier to digest)
  • Feed low fat meals (fat takes longer to digest than lean protein)
  • Warm the food to body temperature (the body has to warm the food before digestion can begin, so pre-warming it streamlines the digestive process)
  • Prevent your dog drinking water with meals (water with food can dilute stomach acid)
  • Use digestive enzymes temporarily to aid digestion
  • Feed your dog earlier in the day (Acid reflux strikes most often at night. By feeding earlier in the day digestion will be further progressed by evening)
  • Rest your dog after eating and avoid excitement around mealtimes

How To Deal With An Acid Reflux Attack As It’s Happening

It is imperative not to feed a dog that is having an acid reflux attack.

Withhold food for at least 24 hours after the symptoms have stopped. An empty stomach is far less prone to acid reflux.

Almost always, an attack will be triggered by eating, and an attack will last longer if the meal has been large and fatty.

During an attack, you may be able to minimize the severity and duration of symptoms by:

  • Positioning your dog with his torso elevated (so the digestive tract is vertical)
  • Taking your dog for a walk (this can serve as distraction and sometimes heads off an attack)
  • Playing calming music or giving a massage, stroking ears etc (Stress can exacerbate acid reflux)

No more vets, potions or complicated regimes. Just simple yet powerful tweaks you can make to your dog’s care to transform his health.

Other Causes Of Air Licking In Boxers

Sometimes licking can be associated with a neurological event or seizure — this will look quite different to lip smacking due to acid reflux. During an acid reflux attack, the dog is in no way cognitively absent or zoned out.

If your dog is experiencing an isolated instance of licking his lips, it may be as simple as having something stuck in mouth.

Check inside, including for anything that may be lodged between the teeth or in the gums. If a foreign body in the oral cavity is to blame for the air licking, the other symptoms associated with acid reflux will, of course, be absent — although you may still notice drooling, which is a general sign of nausea in dogs.


If your Boxer dog is smacking his lips for no apparent reason, consider whether it could be acid reflux.

Look for other classic symptoms of GERD like jaw snapping, neck stretching, loud swallowing and drooling.

A course of drugs, poor food or other sources of toxicity can create acid reflux in Boxers.

Drugs are often prescribed to moderate symptoms but an overhaul of the dog’s total care, including diet, is required to actually heal the condition.
