Regurgitation in a French Bulldog puppy is often dismissed as fussy eating or 'eating too fast'. It frequently is not.
Regurgitation is not vomiting
The distinction matters diagnostically. Vomiting is active — retching, abdominal contraction, warning. Regurgitation is passive: the food simply reappears, often tubular in shape and undigested, with no warning at all. If you can describe it as 'it just fell out of him', that is regurgitation, and it points at the oesophagus rather than the stomach.
The BOAS connection
This is the useful insight. A dog fighting to inhale through an obstructed airway generates strongly negative pressure inside its chest with every breath. That pressure acts on the stomach, drawing it up through the diaphragmatic hiatus. Treat the airway, and in a meaningful proportion of dogs the hernia and reflux improve or resolve without any gastrointestinal surgery.
This is why a good surgeon assessing a Frenchie for BOAS will ask carefully about regurgitation, and why the two problems should be considered together rather than referred to separate specialists.
Signs to look for
- Bringing up undigested food shortly after eating, without retching
- Frequent swallowing, lip licking or gulping
- Foamy white or clear fluid brought up
- Poor weight gain in puppies
- Coughing or aspiration pneumonia in severe cases
- Discomfort when lying down after meals
What causes it
- Congenital laxity of the oesophageal hiatus
- Chronic negative intrathoracic pressure secondary to airway obstruction
- Reduced lower oesophageal sphincter tone
How it is diagnosed
Contrast fluoroscopy visualises the hernia dynamically and is the most useful test. Plain radiographs may miss an intermittent sliding hernia entirely. Endoscopy assesses oesophageal inflammation.
Treatment options
- Treating the underlying BOAS, which resolves or improves many cases
- Acid suppressants and prokinetic medication
- Small, frequent meals, sometimes fed from an elevated position
- Surgical repair of the hiatus in refractory cases
Reducing the risk
- Address airway obstruction early, before chronic reflux damages the oesophagus
- Feed small, frequent meals rather than one large one
- Avoid exercise immediately after eating
- Keep the dog lean
Insurance: Insurers may link this to BOAS as a single respiratory condition for limit purposes, or treat it separately as a gastrointestinal one. If BOAS is already excluded on your policy, expect an argument about whether reflux falls under that exclusion.
What we would actually buy
Lifetime cover with per-condition limits that hold up against a single IVDD surgical episode. Compare the per-condition limit rather than the headline annual figure.

Best for:Summer months, and any dog with diagnosed BOAS
Check current priceA collar loads the throat of a dog whose airway is already restricted. A Y-front harness sits across the chest and leaves the trachea clear, which is the single cheapest intervention that meaningfully improves breathing on a walk.

Common questions
Why does my French Bulldog bring up food after eating?
Most commonly reflux or a sliding hiatal hernia, frequently secondary to airway obstruction. A slow-feeder bowl is worth trying, but persistent regurgitation warrants proper investigation rather than repeated changes of bowl and food.
Does BOAS surgery help hiatal hernia?
Often, yes. Relieving the airway obstruction removes the negative pressure that draws the stomach through the diaphragm, and reflux improves or resolves in a substantial share of dogs without any separate abdominal surgery.
