Dog Choking and Blocked Airway: The Order That Works

Quick answer

A choking dog gives you a few minutes at most. Knowing the order beforehand is the only thing that makes those minutes count.

A dog that is genuinely choking is quiet. Coughing, retching and honking mean air is still moving, which is frightening but far better. Silence with frantic effort means the airway is closed.

The order is: look, then clear what you can see and grip, then back blows, then abdominal thrusts, then check again. A blind finger sweep is not on that list, because it drives objects deeper and gets people bitten badly enough to need their own hospital trip.

• Complete obstruction is silent. Partial obstruction is noisy. The noisy dog has more time.
• Gums turn from pink to grey, blue or purple as oxygen falls. On a black-gummed dog, look at the underside of the tongue or the inside of the lower eyelid.
• Balls that fit fully behind the back teeth are the classic killer, particularly in retrievers and other large-mouthed dogs.
• Pull the tongue forward before anything else. It opens the view and sometimes dislodges the object on its own.
• Go to a vet even if it clears. Fluid can flood the lungs hours later because of the struggle itself.

Never push your fingers blindly down a choking dog's throat.

You cannot feel the difference between a foreign object and the epiglottis or the base of the tongue, so a blind sweep usually pushes a wedged object past the point where it can be reached and turns a partial obstruction into a complete one. A panicking dog also bites without any warning signal, and hands go into the back of a mouth full of carnassial teeth.

Look first. Remove only what you can see and get a grip on.

Why a dog's airway blocks the way it does

The dog's larynx sits at the back of the throat, guarded by the epiglottis, a flap that folds back over the airway during swallowing. Everything a dog does with its mouth involves that flap opening and closing many times a minute.

An obstruction is dangerous in proportion to how well it seals, not how big it is.

A smooth ball roughly the diameter of the throat is the worst possible shape. It seats over the laryngeal opening, forms a seal, and presents a wet convex surface with nothing to hook a finger behind. Suction from the dog's own inspiratory effort then holds it in place. This is why tennis balls and similar smooth balls kill retrievers, spaniels and other large-mouthed dogs that carry things: the ball is not too big to swallow, it is exactly the wrong size.

Irregular objects such as sticks, bones and chew fragments more often lodge partially, which leaves an air channel. Those dogs are noisy, panicked, and in less immediate danger.

Two more failure points matter.

A bone or a stick can wedge across the hard palate between the upper carnassial teeth, or jam vertically between the lower jaws. The dog cannot close its mouth, drools heavily, paws at its face and screams. Breathing is fine. Owners routinely start abdominal thrusts on these dogs, which does nothing except add abdominal trauma.

An object can also lodge in the oesophagus, most often at the thoracic inlet, at the heart base, or just in front of the diaphragm, which are the three points where the tube is least able to stretch. Breathing is normal because the airway is untouched. This is still urgent, because a lodged object presses on the oesophageal wall and the tissue underneath starts to die within hours.

What a blocked airway actually looks like

Lift the lip and read the gum colour. Healthy pink means oxygen is still reaching tissue. Grey, blue or purple means it is not, and the clock is short.

Learn your dog's normal gum colour and the feel of a normal mouth now, while nothing is wrong. Salmon pink, moist, and slippery is the baseline for most dogs.

Many dogs have pigmented gums, and some are black throughout. On those dogs, use the underside of the tongue, the inner surface of the lower eyelid, or the skin inside the flank, all of which stay unpigmented in most individuals.

Complete obstruction.

No noise. The chest and abdomen heave against nothing, so you see enormous effort and hear almost none. The dog claws at its own face, often hard enough to injure itself, then becomes suddenly quiet as consciousness fades. Gums shift through pale to grey to blue. Collapse follows within a few minutes.

Partial obstruction.

Harsh noisy breathing, coughing, gagging, retching, extended neck, elbows held away from the body. The dog is trying to get a wider airway. Gums usually stay pink at first. This dog needs a vet urgently but does not need you to hit it or squeeze it.

Late signs after either.

Wobbling, sitting down, loss of bladder control, then unconsciousness. If the dog is limp, the emergency has moved on from an obstruction to a resuscitation.

The order that works

One. Get the mouth open and pull the tongue forward.

Kneel beside the dog, not in front of it. Grip the upper jaw from above with your thumb and fingers behind the canines, press the lips over the upper teeth so the dog's own lip is between its teeth and your hand, and open. Take the tongue and draw it forward and out. Traction on the tongue alone lifts the base of the tongue off the larynx and sometimes brings a loose object with it.

Two. Look, with light.

Phone torch, from the side. You are looking for something you can both see and get a grip on.

Three. Remove only what you can grip.

Hook a finger in from the side of the mouth and behind the object rather than pushing at its face. For a wedged stick or a bone across the palate, use both hands and lever it out, or use pliers if it is jammed hard. Anything with a hook or a needle in it stays where it is: that goes to the vet intact.

Four. Ball behind the tongue: push from the outside.

If a ball has seated at the back of the throat and cannot be gripped, place both thumbs under the jaw behind the ball, on the outside of the throat, and push firmly upward and forward. You are trying to squeeze it back out of the pharynx toward the mouth. This works when fingers do not, because the ball is being pushed from behind rather than pulled from a surface that offers no purchase.

Five. Back blows.

Get the dog's head lower than its chest. Lift the hindquarters of a large dog, hold a small dog with its spine along your forearm and its head down. Strike firmly between the shoulder blades with the flat of your hand, four or five times. Firmly is the operative word, because a light tap does nothing.

Six. Abdominal thrusts, silent dog only.

Standing dog: stand or kneel behind it, hands clasped in the soft hollow just behind the ribcage below the breastbone, and thrust sharply inward and upward. Small dog: hold its back against your chest, same hand position, same direction. Do a small run of thrusts, then stop and look in the mouth again, because a thrust often moves an object into view without expelling it.

Seven. Alternate and reassess.

Back blows, look, thrusts, look. Do not do one technique continuously without checking the mouth, because the whole point of each is to make the object reachable.

Long-nosed pliers, a torch and a carrier or blanket for transport do more in an airway emergency than any medication in the kit. Know where they are before you need them.

If the dog goes limp

An unconscious dog is easier to help, not harder. The jaw muscles relax, so the mouth opens fully and you can finally see and reach the back of the throat properly. Bite risk drops to almost nothing.

Pull the tongue right out, look with a torch, and clear anything you find.

Then check for breathing by watching the chest for movement and feeling for air at the nose. If there is none, start chest compressions. Lay the dog on its side. For most dogs, compress over the widest part of the chest. For a deep, narrow-chested dog such as a greyhound or a doberman, compress directly over the heart, just behind the elbow. For a barrel-chested flat-faced dog such as a bulldog, lay it on its back and compress over the breastbone.

Push down about a third to a half of the chest width, let the chest fully recoil, and aim for 100 to 120 compressions a minute, the rate used in veterinary CPR guidelines and the same rate taught for people. If someone else can drive, do compressions in the car.

Compressions alone are worth doing. If you have been trained to give rescue breaths, close the mouth, seal your lips over the nose and give a breath every thirty compressions or so, watching for the chest to rise. If the chest does not rise, the airway is still blocked and clearing it comes first.

After it clears, the injury that arrives later

A dog that looks like this an hour later is still not out of it. The two complications that follow a severe airway obstruction both take hours to declare.

Two things follow a serious obstruction, and both are missed by owners who understandably feel the crisis is over.

Laryngeal swelling.

The struggle, the object, and often your own attempts to reach it all inflame the larynx. Swelling in a tube narrows it disproportionately, so a modest amount of oedema in an already irritated airway can re-obstruct a dog several hours later. Noisy breathing that gets worse rather than better after the object is out is this, and it is treated with anti-inflammatories and oxygen, not with more first aid.

Fluid in the lungs from the struggle itself.

When a dog makes violent inspiratory efforts against a closed airway, the pressure inside the chest swings far below normal. That pressure gradient pulls fluid out of the pulmonary capillaries into the air spaces. The dog can appear to recover fully, then over the following hours become restless, breathe fast and shallow, refuse to lie down, and cough up pink froth.

This is a genuine emergency and it is the reason a vet check after a resolved choke is not a formality. Any dog that lost consciousness, went blue, or struggled hard for more than a few seconds should be seen and observed.

Aspiration.

Dogs frequently vomit during a choking episode, and material inhaled into the lungs sets up pneumonia over one to three days. A fever, a wet cough and lethargy in the days after a choke is that, and it needs antibiotics chosen by a vet, not waiting.

Preventing the next one

Prevention here is almost entirely about object selection, and it is unusually effective, because the same handful of items account for most cases.

Balls.

The test is simple. If the ball can pass fully behind the back teeth, it is too small for that dog, no matter what the packaging says. Buy the size up. Balls on ropes are safer because the rope stays outside the mouth and gives you something to pull. Solid rubber balls without a hollow centre are harder to compress into the throat than hollow ones.

Chews.

The problems are chews that soften and are then swallowed whole, and chews that break into a swallow-sized lump near the end. Rawhide, compressed chews, pig ears and dried tendon all reach that stage. Take the end piece away rather than letting the dog finish it. Cooked bones splinter and lodge; raw weight-bearing bones fracture teeth and can still lodge whole.

Sticks.

Never throw a stick. A stick that lands point-up and is caught at speed impales the back of the mouth and throat, and those injuries are deep, dirty, and often discovered late when an abscess forms in the neck. Carry a proper throwing toy on walks so there is an alternative to hand.

Food gulping.

Dogs that inhale meals, particularly in multi-dog homes where eating is a race, choke on kibble and on large treat pieces. Feed separately, use a slow feeder or a scatter feed, and break treats down for a dog that swallows them whole.

Household objects.

Squeakers pulled out of soft toys, corn cobs, stone fruit pits, plastic bottle caps, children's toys, and the plastic ring from a milk bottle are recurring culprits. Puppies and adolescent dogs collect these; so do dogs left alone with a toy that has started to come apart.

Region matters for what is on the shelf.

Chew types, toy safety standards and the availability of things like corn cobs and stone fruits vary a great deal between countries and seasons. Judge the object in front of you against the size and chewing style of your own dog rather than against a label.

What never to do

Do not sweep blindly. Look, then remove.

Do not do abdominal thrusts on a dog that is making noise, coughing, or breathing. Air is moving. You will injure the abdomen and change nothing.

Do not hold a large dog fully upside down by the hind legs. The weight compresses the chest and the dog can be dropped on its head. Lift the hindquarters so the head is lower, and no further.

Do not pour water down the throat to wash something down, and do not attempt to make the dog vomit. Both add fluid to an airway that is already compromised.

Do not pull on anything with string, thread or fabric attached that disappears down the throat. A linear object may be anchored much further down, and pulling can cut the tissue it is looped around.

Do not skip the vet visit because the object came out and the dog wagged its tail. The two complications that kill afterwards both take hours to appear.

Do not wrap the neck or apply pressure to the throat, and take the collar off. A tight collar over a swollen larynx makes a marginal airway worse.

When to get help

Call the nearest emergency clinic while you are working, not after. Say the words "my dog is choking" so the practice can prepare, and ask whether to come straight in. In most regions an out-of-hours service is a different site from your daytime practice, which is exactly the sort of thing to find out before an emergency rather than during one.

Go in immediately, regardless of how the dog looks now, if any of these are true:

• The dog lost consciousness at any point
• Gums went grey, blue or purple
• Breathing is still noisy after the object is out
• The object came out in pieces and you cannot account for all of it
• The dog is retching, gulping or drooling with normal breathing
• Anything with a hook, needle, string or thread is involved
• The dog was struck or thrust hard enough that abdominal injury is possible

Expect the vet to give oxygen first, sedate or anaesthetise the dog to examine the larynx directly, take radiographs knowing they may show nothing, and pass an endoscope if the oesophagus is suspected. Anti-inflammatories are commonly given for laryngeal swelling. A dog that struggled severely is usually kept in for several hours of observation specifically to catch fluid building in the lungs, and in the rare worst case a temporary tracheostomy buys time while swelling settles.

Bring the object, or what is left of it, and the packaging. Tell them what time it happened, how long the dog was in difficulty, whether it collapsed, whether it vomited, and what you did. That history decides how long the dog is watched, and being watched is the part that catches the complication that arrives late.
