Esophageal Disease in Chow Chows

Was there effort? Vomiting is an active process with visible abdominal heaving. Regurgitation is passive, sometimes happening while the dog simply lowers its head.

Was there warning? Dogs about to vomit typically drool, lick their lips, swallow repeatedly and look uneasy for a minute or two beforehand. Regurgitation arrives without any of that.

What did the material look like? Vomit is partly digested and often contains yellow bile. Regurgitated food is usually undigested, sometimes still in the shape of the tube it came from, and coated in clear or white foam.

How long after eating? Regurgitation is frequently within minutes of a meal, though a badly dilated oesophagus can hold food for hours. Vomiting is more variable.

Did the dog try to eat it again immediately, apparently unbothered? That casual response is much more typical of regurgitation.

Is there a cough or noisy breathing alongside? This is the question that changes urgency, because it suggests material has gone into the lungs.

Write the answers down before the appointment. A vet asking these questions is trying to sort the problem into one of two very different categories, and a clear account from someone who was there is better evidence than anything else available.

Food entering the lungs causes aspiration pneumonia, which is a serious and sometimes fatal complication. Any cough in a dog that regurgitates is a same-day veterinary problem.

If you think your Chow 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 hip dysplasia, elbow dysplasia, entropion.

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.
