My dog has swallowed an object

Q: What should I do if my dog swallows a wasp?

A sting in the mouth or throat can cause swelling and make breathing difficult. Watch for a swollen face or lips, sudden drooling, trouble breathing. At the slightest swelling or shortness of breath, it's an emergency: call and go now. Don't give any human antihistamine on your own initiative.

Q: My dog swallowed something but seems fine, should I worry?

'They seem fine' doesn't mean 'it's passed': the object can block further down with no immediate sign. Call your vet so they can decide whether to monitor or X-ray, and never make them vomit.

Q: How long does it take a dog to pass a swallowed object?

From a few hours to several weeks depending on the object, and some never pass (MSD Veterinary Manual). Don't sit watching the food bowl or the toilet and hoping: call your vet at the first doubt, they're the one who judges.

Q: My dog swallowed a piece of wood or a pebble, is it serious?

Wood can split into splinters and a pebble can block the intestine. Vomiting after chewing wood is never trivial. Watch for digestive signs and ask your vet's advice; never pull on a stuck piece.

Your dog has just swallowed something? Never make them vomit, and if a thread or a piece of string is hanging from their mouth or their bottom, whatever you do, don't pull on it. Quickly note what, when and how much, then call your vet or a pet poison helpline without waiting for symptoms: only they can judge whether to monitor, X-ray or operate.

Why every hour counts

A swallowed object can block the gut completely, and a blockage left untreated puts a dog's life in danger very quickly. Size changes everything: the sock that passes through a Labrador without trouble will block a Chihuahua, because their gut is far narrower. The smaller your dog, the bigger the object is for them. An object can take anything from a few hours to several weeks to come out, and some never come out without the vet's help: don't count on "it'll pass on its own".

What to do straight away

Three simple things, in this order, while you wait for the vet's advice.

Make things safe and stay calm

Move your dog away from anything else they could swallow. If you have an identical object (the matching sock, another piece of the same toy), keep it to show the vet.

Note what, when and how much

The object, the time it was swallowed and how much went down all help your vet decide what to do.

Call your vet or a pet poison helpline

Don't wait for symptoms before you call. Describe the situation and follow their instructions: monitor at home, come in for an X-ray, or head straight over.

String-like objects (string, thread, wool, elastic bands, ribbon, dental floss) are the most dangerous of all: one end gets stuck, the gut bunches up around it and the thread can saw right through it. If a thread is hanging out, never pull: go straight to the vet.

The riskiest objects

Not all swallowed objects are equal. Some call for maximum vigilance.

Maximum vigilance

Button batteries, magnetsA battery can burn the stomach within hours, and several swallowed magnets attract each other through the gut wall and can pierce it: go to the vet right away, even if your dog seems perfectly fine.

String, thread, wool, elastic bands, ribbon, dental flossThey can saw through the gut, or pierce it.

Cooked bones, sticks, sharp objectsThey splinter, or get stuck in the throat, the stomach or the gut.

Socks, balls, bits of toy, fruit stones, stones, bottle topsThey are exactly the right size to block the gut.

Also worth flagging straight away

Any toxic food or productChocolate, grapes, medicines, plants: call a pet poison helpline without waiting for symptoms.

A stick picked up outdoors is not a safe toy: go for a chew toy made for the job, and stay nearby while your dog uses it.

The signs that should alert you

After the object goes down, watch for these signs and report them to the vet.

Keep an eye on it

Your dog has swallowed something but stays lively, eats and drinks
A one-off bout of vomiting, then straight back to normal

Call the vet

Repeated vomiting, refusing food
Low, flat mood, painful or tense belly
No more stools and no wind (the gut has stopped moving)
Sudden, heavy drooling

Life-threatening emergency

Retching with nothing coming up, with a belly that swells and hardens
Unable to breathe, blue gums, pawing at the mouth
Collapse or an unsteady, staggering walk

Your dog is choking (panicking, pawing at the mouth, gums turning blue), their belly is swelling with retching and nothing coming up, or you suspect something toxic: this is a life-threatening emergency.

Do this right now

Keep your dog calm, and put nothing blindly into their mouth
Call the vet practice or a pet poison helpline on the way
Go now: with choking and with a twisted stomach, every minute counts

Call your vetor an animal poison control centre: without delay.

The assistant never replaces a vet. When in doubt, call.
