Can Donkeys Vomit? Regurgitation, Choke-Like Signs & Emergencies

Donkeys do not commonly vomit. In equids, material coming out of the nose or mouth is much more likely to be regurgitation related to esophageal obstruction, often called choke, than true vomiting. Merck notes that in horses, choke commonly causes drooling, coughing, repeated swallowing attempts, and discharge of saliva or feed from the nose. Those same emergency principles are used for donkeys in practice.

The most common cause of vomiting-like signs in a donkey is feed lodged in the esophagus. This can happen with dry pellets, poorly chewed feed, rapid eating, dental disease, dehydration, or eating while stressed or competing with herd mates. ASPCA equine guidance also notes that dental disease can contribute to choke, colic, and weight loss, which is one reason older donkeys and those with poor dentition deserve extra attention.

Less common causes include swallowing dysfunction, trauma to the throat or esophagus, esophageal narrowing after a previous choke episode, sedation-related swallowing problems, and severe neurologic or muscular disease. In some cases, pet parents may mistake nasal discharge from respiratory disease for regurgitation, especially if the donkey is coughing at the same time.

The biggest concern is not whether the donkey "threw up." It is whether feed, saliva, or water has been aspirated into the lungs, because aspiration pneumonia is a well-recognized complication after equine choke. Even a partial obstruction can become serious quickly.

See your vet immediately if your donkey has feed or greenish fluid coming from the nostrils, repeated swallowing, gagging-like motions, coughing, distress, neck stretching, or any trouble breathing. A severe choke is often obvious, but milder cases can be confused with colic or an upper airway problem. Because aspiration pneumonia can follow, early veterinary help is the safest choice.

While you wait for your vet, remove all feed and hay. Keep your donkey calm with the head in a natural, lowered position if possible, and avoid forcing water, syringing liquids, or giving mineral oil by mouth. Merck specifically warns against giving mineral oil to a choking equid because it can be inhaled into the lungs and cause serious damage.

Home monitoring alone is only reasonable after your vet has assessed the donkey and confirmed the episode has resolved or is mild enough for watchful follow-up. If your vet recommends monitoring, watch closely for fever, cough, faster breathing, depression, reduced appetite, or nasal discharge over the next 24 to 72 hours. Those can be early signs of aspiration pneumonia and need a recheck.

If you are unsure whether it is choke, colic, or a respiratory problem, treat it as urgent anyway. Donkeys often hide illness well, so subtle signs can still mean a significant problem.

Your vet will start with an exam focused on breathing, hydration, heart rate, temperature, and whether the donkey can swallow. They may sedate your donkey to reduce anxiety and esophageal spasms, then pass a nasogastric tube to check for obstruction and, if appropriate, gently flush the esophagus. Merck describes sedation and tubing with lavage as standard first steps for equine choke.

Depending on the case, your vet may recommend endoscopy, bloodwork, chest ultrasound, or radiographs, especially if the obstruction does not clear quickly, the donkey has repeated episodes, or there is concern for aspiration pneumonia or esophageal injury. If the blockage has been present for a while, or if repeated attempts fail, referral for hospital care and more advanced imaging may be needed.

Treatment after the obstruction clears often focuses on preventing complications. That may include anti-inflammatory medication, fluids, temporary diet changes such as soaked feeds or slurry meals, and monitoring for fever or lung changes. Some donkeys also need a dental exam later if poor chewing likely contributed.

If aspiration pneumonia, esophageal damage, or a stricture develops, care becomes more involved and may include hospitalization, repeated imaging, antibiotics when indicated by your vet, and longer-term feeding adjustments. Recovery can still be good, but the timeline and cost range increase.

Home care starts after your vet has examined your donkey and given a plan. Follow feeding instructions closely. Many donkeys recovering from choke do best on soaked pellets, mash, or another softened ration for a period of time, with hay and dry feeds adjusted based on your vet's advice. Offer meals slowly and in a calm setting so your donkey is less likely to bolt feed.

Take your donkey's temperature once or twice daily for the next few days if your vet recommends it, and watch for cough, nasal discharge, reduced appetite, depression, or faster breathing. These changes can show up after the obstruction seems resolved. Keep fresh water available only as directed by your vet, since some cases need a short period of controlled reintroduction.

Longer term, prevention matters. Ask your vet about a dental exam, feed texture, soaking pellets or cubes, adding extra water to meals, and ways to reduce competition at feeding time. Older donkeys, those with missing teeth, and those with a history of choke may need permanent feeding changes.

Do not give oral oils, drenches, or medications unless your vet specifically tells you to. If signs return, or if your donkey develops fever or breathing changes, see your vet immediately rather than trying another home remedy.
