You’re standing in the kitchen, and your heart just hit the floor. Maybe it was a bar of dark chocolate, a handful of grapes, or that bottle of Advil you left on the nightstand. Your dog looks fine right now, wagging their tail, totally oblivious to the fact that they just swallowed something potentially lethal. You need to know what can I give my dog to induce vomiting before that poison hits their bloodstream. It’s a race against the clock.
But here’s the thing: making a dog throw up isn't like hitting a reset button. It’s a medical procedure. If you do it wrong, or if you do it when you shouldn't, you could actually make things ten times worse. You might cause aspiration pneumonia, where they inhale the vomit into their lungs, or you could cause chemical burns on the way back up.
Stop. Breathe. Before you reach for anything in your pantry, you need to understand the "When," the "How," and the "Absolutely Never."
The Only Safe Substance: 3% Hydrogen Peroxide
If you are at home and a vet has given you the green light, there is really only one answer to the question of what can I give my dog to induce vomiting. That is 3% hydrogen peroxide. Not the 6% stuff people use to bleach hair. Not salt. Definitely not Ipecac.
Hydrogen peroxide works because it’s a mild irritant to the dog’s digestive tract. When they swallow it, it bubbles up, creates gas, and essentially "fools" the stomach into thinking it needs to evacuate everything immediately. According to the ASPCA Animal Poison Control Center, this is the standard home recommendation, but it’s not universal for every dog.
The dosage is usually one teaspoon per five pounds of body weight. However, you should never exceed three tablespoons, even if you have a Great Dane. You use a needleless syringe or a turkey baster to squirt it into the back of their mouth. Then, you wait. You walk them around. Movement helps the bubbles do their thing. If they don't vomit within 15 minutes, you can usually give one more dose, but if that fails, you stop. Period.

Why the Concentration Matters
People get careless. They see "peroxide" and grab whatever is in the cabinet. If you use a higher concentration than 3%, you are essentially pouring a corrosive chemical down your dog's throat. This can lead to severe ulceration of the esophagus and stomach lining.
When Making Them Barf is a Terrible Idea
Sometimes, the "cure" is deadlier than the poison. If your dog swallowed something caustic—think drain cleaner, battery acid, or oven cleaner—inducing vomiting is the last thing you want to do. Why? Because that chemical burned the throat on the way down. It will burn it even worse on the way back up.
The same goes for hydrocarbons like gasoline or motor oil. These substances are "slippery." If a dog vomits them, they are highly likely to inhale the droplets into their lungs. This causes aspiration pneumonia, which is often harder to treat than the original poisoning.
Then there’s the physical state of the dog. Is your dog acting lethargic? Are they wobbly on their feet or having a seizure? If the dog is already showing neurological signs, their gag reflex is likely compromised. If you try to force hydrogen peroxide down a semi-conscious dog, you are basically pouring liquid directly into their lungs.
And please, check the breed. Brachycephalic dogs—the smoosh-faced ones like Pugs, Bulldogs, and Boxers—have a much higher risk of inhaling their own vomit due to their unique airway anatomy. Most vets will tell you to never, ever induce vomiting at home for these breeds. Get them to an ER.

The Danger of "Old Wives' Tale" Remedies
Internet forums are full of dangerous advice. You’ll see people suggesting you put salt on the back of a dog’s tongue. This is incredibly dangerous. Salt can cause hypernatremia (salt poisoning), which leads to brain swelling and death. You’re trying to save them from a chocolate bar and you end up killing them with salt. It’s not worth it.
Ipecac syrup is another one. It used to be in every first aid kit. Now? It’s considered toxic to dogs because it can cause heart issues if not cleared from the system. Mustard powder is another "remedy" that rarely works and just wastes precious time.
Time is your most valuable resource. If you spend twenty minutes trying to find a YouTube tutorial on how to feed your dog dry mustard, that’s twenty minutes the poison has had to move from the stomach into the small intestine. Once it’s in the intestine, vomiting does nothing.
What to Do Before You Act
Before you search for what can I give my dog to induce vomiting, you need to call someone.
- Your Local Vet: If it’s during business hours, call them immediately.
- ASPCA Poison Control (888-426-4435): There is a fee, but they have a database of every chemical and plant known to man. They will tell you exactly if that specific brand of sugar-free gum contains enough Xylitol to be fatal for your dog’s specific weight.
- Pet Poison Helpline (855-764-7661): Another world-class resource.
When you call, have the packaging of whatever they ate in your hand. Vets need to know the active ingredients. "He ate some blue pills" doesn't help. "He ate 20mg Prozac tablets" does.

The Veterinary Alternative: Apomorphine
If you can get to a vet within 30 to 60 minutes, that is always the better choice. Vets don't use hydrogen peroxide. They use a drug called Apomorphine.
Apomorphine is fascinating. It’s a dopamine agonist that hits the vomiting center in the brain directly. In many clinics, they actually place a tiny tablet in the dog's conjunctival sac (the corner of the eye). It works almost instantly. Once the dog has cleared their stomach, the vet can wash the eye out to stop the nausea, or give a reversal agent like Maropitant (Cerenia).
This is infinitely safer because the vet can also administer IV fluids, activated charcoal to soak up remaining toxins, and monitor the dog's heart rate.
Actionable Steps for the Next 10 Minutes
If you are currently in an emergency situation, follow this exact sequence:
- Identify the toxin. If it's a plant, take a photo. If it's a chemical or food, grab the wrapper.
- Check the clock. If it has been more than two hours, the stomach is likely empty anyway, and inducing vomiting is useless.
- Assess the dog. Are they alert? Can they stand? If they are dizzy or sleepy, do not give them anything by mouth.
- Call for professional advice. Don't wing it. Tell the vet your dog's weight and what they ate.
- Prepare the 3% Hydrogen Peroxide. If the vet says "go ahead," use a syringe to ensure the liquid goes into the mouth, not the nose.
- Watch for results. Keep the dog on a surface that is easy to clean (not your white shag carpet).
- Collect a sample. It’s gross, but your vet might need to see what came up to confirm the toxin was expelled.
Once the crisis has passed, don't assume they are out of the woods. Some toxins, like grapes or certain mushrooms, cause kidney or liver failure days later. A follow-up vet visit for bloodwork is usually non-negotiable. Keeping a "Pet Emergency Kit" with fresh 3% hydrogen peroxide (it loses potency over time once opened), a syringe, and the poison control numbers can save your dog's life. Check the expiration date on that peroxide today—if it doesn't fizz when you pour a little in the sink, it won't work on your dog.
