Is choke an emergency in horses?

Yes — call your vet immediately. A horse with choke can still breathe, because the blockage is in the oesophagus rather than the airway, but according to World Horse Welfare the risk of complications such as oesophageal rupture increases with delayed treatment, and aspiration pneumonia can develop days later.

What are the first signs of choke in a horse?

Green, slimy discharge containing feed material coming from the nostrils, excessive drooling, coughing and retching, an outstretched neck, and sometimes a hard lump on the left side of the neck. Discomfort can look similar to colic.

Should I give my horse food or water during choke?

No. World Horse Welfare advises removing all sources of food and water while waiting for the vet, giving no oral medications, and never trying to flush the blockage with a hose — this is likely to do more harm than good.

How can I prevent choke in horses?

Soak expanding feeds such as sugar beet pulp thoroughly, dampen bucket feed, feed forage before concentrates, provide routine dental care (every six months for senior horses), feed from the floor where possible, and slow down fast eaters with large smooth rocks in the bucket.

Can choke clear on its own?

Many cases resolve as the horse relaxes, but you should still contact your vet. Food or water can pass into the lungs and cause aspiration pneumonia, which can take days to develop, so your vet may wish to prescribe preventative antibiotics.

Horse Choke in the UK: Emergency Guide

Published 18 July 2026Last updated 18 July 20265 min read

Quick answer

Choke is a blockage of the horse's oesophagus — the horse can still breathe, but it is an emergency. According to World Horse Welfare, look for green, slimy discharge from the nostrils, drooling and retching. Call your vet immediately, remove all food and water, and keep the horse calm.

**Call your vet immediately**, remove all food and water, and keep the horse calm.

What is choke?

Choke — oesophageal obstruction — happens when food or a foreign object lodges in the horse's oesophagus, the muscular tube carrying food from the mouth to the stomach.

Unlike choking in humans, the blockage is not in the airway, so a horse with choke can still breathe. However, according to World Horse Welfare, it is still an emergency: delayed treatment increases the risk of oesophageal rupture, and food or saliva passing into the lungs can cause aspiration pneumonia.

Horses cannot vomit, so material backs up and comes out through the nostrils and mouth instead.

Signs of choke

Sign	What you may see
Nasal discharge	Green, slimy material containing feed coming from one or both nostrils, often intermittent
Drooling	Excessive saliva, sometimes frothy
Coughing and retching	Repeated attempts to swallow, gagging
Neck posture	Head and neck held outstretched; horse looks anxious
Lump in the neck	A hard swelling on the left side of the neck where the oesophagus runs
Colic-like discomfort	Restlessness, pawing or looking at the belly

Some horses initially keep trying to eat despite the blockage. According to UK equine vets, discomfort from choke can closely resemble colic — either way, the response is the same: call the vet.

What to do while waiting for the vet

Call your equine vet immediately — describe the signs and say when the horse last ate
Remove all food and water — nothing by mouth until the vet advises
Keep the horse calm — a quiet, settled horse is more likely to relax the oesophagus and clear the blockage
If turned out — bring the horse in, or walk and/or muzzle them to prevent further eating
Gentle massage — if you can feel a lump on the left side of the neck, World Horse Welfare says it can be gently massaged if the horse tolerates this
No oral medications — do not syringe anything into the mouth
Never insert a hose or tube down the horse's throat — this is very likely to do more harm than good

What the vet may do

According to World Horse Welfare, the vet will usually sedate the horse to relax the oesophageal muscles. They may give intravenous fluids to maintain hydration, or pass a nasogastric tube to flush the blockage gently with water, softening it so it passes.

If the vet suspects food or saliva has entered the windpipe, they may prescribe preventative antibiotics against aspiration pneumonia, plus anti-inflammatory medication to settle oesophageal spasm.

Aftercare and monitoring

Complications can take days to appear, so monitor closely after the incident:

Take your horse's temperature daily and report any fever
Watch for coughing, nasal discharge or difficulty breathing — possible aspiration pneumonia
Feed only soft, wet mashes for a few days if your vet advises, to let the oesophagus recover
Soak all feed and hay thoroughly before the horse returns to normal rations

Preventing choke

According to World Horse Welfare and UK equine vets:

Soak sugar beet pulp and other expanding feeds thoroughly before feeding — dry sugar beet is a classic choke cause
Dampen bucket feeds with water to help passage down the oesophagus
Feed hay or forage before concentrates, or add chaff to the bucket, so hungry horses do not bolt hard feed
Routine dental care — older horses and those with missing or uneven teeth cannot chew properly; senior horses may need checks every six months
Feed from the floor where possible, and keep forage available as near to 24/7 as you can
Slow the bolters — large, smooth rocks in the feed bucket or slow feeders force greedy horses to take their time
Space horses at group feeding to prevent competition and rapid eating
Never feed a sedated horse — wait until they are fully awake, as chewing is impaired

When to call the vet

Immediately — choke is never a wait-and-see condition. Even if the blockage clears by itself, phone your vet for advice, because aspiration pneumonia and oesophageal damage can follow an apparently mild episode.
