Quick answer
How do I tell regurgitation from vomiting?
Regurgitation is effortless and silent, with undigested food often in a tube shape and coated in mucus. Vomiting involves nausea, drooling and abdominal heaving, and produces partly digested material or bile.
Vomiting is an active event with warning. Regurgitation is passive and silent, and a tube of undigested food arrives on the floor with no retching at all.
Owners cleaning up after a dog that brings food back most days, and owners of a Papillon puppy that started producing food shortly after weaning onto solids.

Oesophageal disease is any failure of the tube that carries food from throat to stomach, whether from loss of muscular coordination, an external constriction, inflammation from acid, or a foreign body lodged in it. Its hallmark is regurgitation rather than vomiting, and its most serious consequence is food inhaled into the lungs. It is not a documented Papillon problem, but the signs are worth recognising in any dog.
Uncommon overall and not documented in Papillons. Congenital forms are typically identified in the first months of life in the breeds where they occur, and acquired forms appear in middle-aged and older dogs of any breed. The reason it is worth knowing about is that owners routinely report it as vomiting, which sends the investigation in the wrong direction.
There is no documented oesophageal predisposition in Papillons, and nothing in the breed's health list points that way. Size shapes the practicalities instead. A five to ten pound dog is easy to hold upright after meals, so the mainstay of management is genuinely achievable here in a way it is not with a large breed. A small dog also aspirates a smaller volume, though its lungs are correspondingly small, so the risk does not disappear.
Feeding practice is the dominant environmental factor once disease exists. Eating from a floor bowl with the head down, lying flat immediately after meals, large single meals, and excitement during eating all work against a weak oesophagus. Swallowed foreign bodies are the other main external cause, and in a small dog it takes very little to obstruct the tube, which is one more reason to avoid bones and rigid chews.
Seek emergency care for a dog that is regurgitating and has developed a cough, rapid or laboured breathing, a fever, nasal discharge or sudden lethargy, since aspiration pneumonia progresses within hours. Also treat as an emergency any dog that is gagging, retching, drooling heavily and unable to keep down even water, which may indicate an obstruction in the oesophagus. Book a prompt appointment for regurgitation happening more than occasionally, for weight loss, or for a puppy that began bringing back food when it moved onto solids, since that history points at a specific and sometimes correctable congenital cause.

Radiographs usually give a preliminary answer at the first visit. A vascular ring corrected surgically in a young puppy improves within weeks, though some dilation may persist. Megaoesophagus without a correctable cause is managed indefinitely, and the first two to three months are spent finding the food consistency and feeding position that work for that individual. Aspiration pneumonia takes two to four weeks of treatment.
A dog keeping its meals down, holding a stable weight, and going months rather than weeks between episodes, with no pneumonia. For a lifelong case, success is a workable daily routine rather than a normal oesophagus, and the honest measure of it is a chest that stays clear.
Effort comes first. Vomiting is preceded by nausea, drooling, restlessness and visible abdominal heaving. Regurgitation happens without any of that; the dog lowers its head and the material simply falls out.
Timing next. Vomiting can occur at any interval after eating. Regurgitation usually happens within minutes to a couple of hours of a meal, and often when the dog puts its head down or changes position.
The material itself is the strongest clue. Regurgitated food is undigested, frequently still in a tube shape moulded by the oesophagus, and it is covered in slippery mucus. Vomit is partly digested and often contains yellow bile.
Acidity, if you happen to test it, is neutral in regurgitation and acidic in vomit.
The dog's behaviour differs too. A regurgitating dog often eats the material immediately and appears untroubled. A vomiting dog looks unwell before and after.
Describing the right one to your vet redirects the entire investigation, from stomach and intestine towards throat, oesophagus and chest.
The danger of oesophageal disease is not malnutrition, though that matters. It is aspiration pneumonia.
Material sitting in a dilated oesophagus is a few centimetres from the entrance to the windpipe. When a dog lowers its head, sniffs, gets excited or lies down, some of it can be inhaled. Food and bacteria in the lungs produce a severe pneumonia that can develop within hours.
The warning signs are a cough that has appeared in a regurgitating dog, rapid or laboured breathing, a nasal discharge, fever, and lethargy. Any of those in a dog with known oesophageal disease is an emergency, not a next-morning appointment.
This is why upright feeding matters so much. Feeding a dog with its front end raised, and holding it in that position for ten to fifteen minutes afterwards, uses gravity to do what the muscle cannot. Purpose-built chairs exist, and for a five to ten pound dog a sturdy box with a cut-out and a non-slip base does the same job for nothing.
Small, frequent meals of the consistency that works best for that individual complete the plan.
If you think your Papillon has esophageal disease, the plan is three steps: write down what you have seen and when it started, book a veterinary appointment rather than waiting for the next flare, and take video of the behaviour or symptom before you go — the thing you are worried about rarely happens in the consulting room. Screening in the parents covers patellar luxation, progressive retinal atrophy, dental disease.
What the vet visit should produce is a diagnosis and a written plan, not just reassurance: what is being ruled out, what the monitoring interval is, and which signs mean you come back sooner. Ask what the treatment costs across a year rather than per visit, because that is the number that decides whether you are managing this condition or reacting to it.
Between appointments, keep a short log — dates, what you saw, what changed. It is the single most useful thing an owner brings to a follow-up, and for esophageal disease it is often what separates a clear pattern from a guess.
Marek had been telling his vet for two months that his Papillon, Lena, was vomiting after meals. Two diet changes and a course of stomach medication had achieved nothing. At the third visit the vet asked him to describe the actual moment. Marek said she just lowers her head and it falls out, there is no heaving, and she eats it again straight away. That description changed the plan. Chest radiographs were taken the same day and showed a dilated oesophagus in the front part of the chest, with a narrowing beyond it consistent with a vascular ring anomaly that had been present since puppyhood but had gone unrecognised. Lena had corrective surgery at a referral centre. She still eats from a raised bowl and is held upright for ten minutes afterwards, but she has gained a pound and has not brought back a meal in eight months.
Key takeaway: One sentence about whether the dog heaved sent the case from the stomach to the chest. Describe the mechanics of the event, not the mess it left.
It is not documented in the breed, whose recorded issues are patellar luxation, progressive retinal atrophy, dental disease, an open fontanel and a collapsing trachea. Megaoesophagus has recognised breed associations elsewhere, including German Shepherds and Great Danes.
A loss of muscular tone and coordinated contraction in the oesophagus, which stretches into a wide, floppy tube that no longer propels food. It can be congenital, appearing when a puppy moves onto solid food, or acquired later in life, sometimes secondary to another disease.
A congenital malformation in which a persisting foetal blood vessel encircles the oesophagus and constricts it, causing food to build up in front of the obstruction. It appears at weaning, is diagnosed by imaging, and is one of the few oesophageal problems that surgery can genuinely correct.
Yes. Stomach acid escaping upward inflames the lower oesophagus, causing discomfort, gulping, lip licking and sometimes regurgitation. It is a recognised complication after anaesthesia and in dogs with a hiatal hernia, and it is generally manageable.
Chest radiographs are the starting point and often show a dilated oesophagus directly. A contrast study or fluoroscopy shows the tube working, or failing to. Bloodwork looks for underlying causes, since acquired megaoesophagus is sometimes secondary to another disease.
It depends entirely on the cause. A vascular ring corrected surgically in a puppy can do very well. Megaoesophagus with no correctable cause is a lifelong management problem, and repeated aspiration pneumonia is what usually determines the outcome. Rigorous upright feeding makes a real difference.
The early signs are set out in the sections above, and they are the reason to book a veterinary appointment rather than wait. Esophageal Disease in Papillons is diagnosed by a vet, not from a symptom list, and the sooner it is on record the more options remain open.
Regurgitation is effortless and silent, with undigested food often in a tube shape and coated in mucus. Vomiting involves nausea, drooling and abdominal heaving, and produces partly digested material or bile.
Aspiration pneumonia. Food inhaled from a dilated oesophagus causes a severe lung infection. A new cough or fast breathing in a regurgitating dog is an emergency.
Chest radiographs with a consultation typically run two to four hundred dollars. Contrast studies or fluoroscopy at a referral centre add several hundred more, and treating aspiration pneumonia can run into thousands.
Upright, with the front end raised, and held in that position for ten to fifteen minutes afterwards. Small frequent meals, and a food consistency chosen by trial, since some dogs manage a slurry better and others meatballs.
Yes, and Papillons take to it quickly. Build up in short rewarded sessions before you need it, so the chair becomes a normal part of mealtimes rather than a restraint.
