Location: Denver, Colorado. My 2-year-ol

Answer

I'll work this carefully. Let me first pull the lookup facts and the right card.

This is an exposure (swallowed foreign body), not a complaint — the right card path is the toxins/foreign body material. Let me find the corn cob / foreign body card.

Corn cob isn't a toxin — it's a foreign body. Let me look at the emergency/triage cards and the dog card to find foreign body guidance.

I have what I need. The "Suspected poisoning/toxin exposure" red-flag row governs all exposures, and the "never induce vomiting" rule applies. There's no corn-cob-specific card, but the principle is well-established: corn cob is a non-digestible foreign body, the vet decides retrieval vs. monitor. Let me draft the answer.

The gate flagged the rule that forbids giving home vomiting instructions — even "never do this" phrasing trips it. Let me reword that bullet so the prohibition is in the right shape.

The last paragraph mentions "induce vomiting under supervision" which also trips the rule. Let me clean that line.

Gate passes. Sending the answer.

**Call an emergency veterinary clinic in Denver now and drive her there.**

A whole 3-inch corn cob swallowed 20 minutes ago is a mechanical foreign-body emergency, not a poison. Corn cob does not break down in stomach acid and its smooth, fibrous shape makes it the kind of object that can lodge at the stomach outlet or anywhere along the small intestine. Your dog is acting normal right now because the cob is still in the stomach; the dangerous window is once it moves into a narrower section of intestine, where it can cause a complete obstruction or even perforate the bowel wall. A normal-looking dog 20 minutes after swallowing is exactly the picture — and it is the reason to leave now, not later.

Your brother is right that something has to happen, and wrong about both options:

- **Do not give 3% hydrogen peroxide at home.** For a foreign body of this size and shape the emergency veterinary route is to get her there, not to manage vomiting at home. A 3-inch cob brought back up without anesthesia can lodge in the esophagus, scratch or perforate it, or be inhaled on the way out and cause aspiration pneumonia. It is also unreliable for objects this large. The vet makes the vomit-or-retrieve decision under controlled conditions, only if the cob is still in the stomach and safe to retrieve that way.
- **Do not feed bread** to "cushion and push it through." Food sitting on top of a cob in the stomach makes endoscopic visualization harder if she does need the camera, and if the cob is already partway down, bread does not push it past a real obstruction; it just adds bulk that may need to come out surgically too.

The golden window you are asking about is real. A dog that arrives within roughly 2–4 hours of swallowing, while the cob is still in the stomach, can often be retrieved with an endoscope under anesthesia — a short procedure, no abdominal incision. Once it has passed into the small intestine the options narrow, and the likely outcome becomes exploratory abdominal surgery. Twenty minutes in, you are still on the right side of that window. Drive now, not in an hour.

**Going and what to bring**

| Do | Do not |
| --- | --- |
| Call ahead so the E team is ready | Give hydrogen peroxide to make her vomit |
| Bring the cob or a same-size piece for size reference | Feed bread, treats, or any other food |
| Note: swallowed at about [time], one whole cob, ~3 inches, no chewing, dog is 22 kg (48 lb), 2-year-old Golden, female, currently acting normal | Wait for vomiting, drooling, or refusing food to "confirm" a problem |
| Drive calmly — keep her from pacing, jumping, or playing | Stop to observe at home first |

On the way, keep her calm and on a leash or in the car; excitement and movement do not help and a vomiting attempt en route is harder to manage. If she starts retching, drooling, gagging, going stiff, or vomiting in the car, that is a sign the cob has moved — tell the clinic by phone while you keep driving.

A few notes on what I can and cannot do this turn:

- I do not have a confirmed animal-poison hotline for Denver in this turn's table, so no number printed from here — your call is the emergency vet, not a national line.
- I am not calculating a "safe size" or "wait-and-see" dose. A 3-inch cob in a 22 kg dog is not a case the family triages at home.
- I am not diagnosing or predicting. The vet who examines her decides the next step: retrieve with an endoscope under anesthesia while the cob is still in the stomach, monitor with serial X-rays, or go to surgery.
