My dog ate something toxic — what to do right now

Step by step

1. Stop further eating. Move your dog away and pick up what’s left. Keep the wrapper, box or bottle.
2. Check your dog. Are they breathing normally, awake and responsive? If they are collapsing, having a seizure or struggling to breathe, go straight to the nearest emergency vet.
3. Call for advice now. Phone your vet, an emergency clinic or a pet poison line. Many poisons, like grapes and xylitol, cause no signs at first. Treatment is easier, safer and cheaper the earlier it starts.
4. Have the details ready: what your dog ate, roughly how much, when, your dog’s weight, and any symptoms.
5. Follow their instructions and don’t leave your dog alone until a professional says the risk has passed.

Should I make my dog throw up?

Not unless a vet or poison line tells you to. Corrosive products like drain cleaner burn the throat again on the way back up. Fuel products can be inhaled into the lungs. A dog already showing signs may be too far along for vomiting to help. Salt, fingers down the throat and cooking oil are all dangerous home “methods”. Even hydrogen peroxide carries risks, so many vets prefer to induce vomiting in the clinic.

Don’t try these home remedies

• Milk — it rarely helps, and many dogs are lactose intolerant.
• Salt or mustard to cause vomiting — salt can be poisonous itself.
• Activated charcoal from the pharmacy — only a vet should decide when it’s appropriate.

Common poisons and why they matter

What your dog ate	Main danger
Chocolate, coffee, caffeine	Racing heart, tremors, seizures. Darker chocolate is worse.
Grapes, raisins, currants	Kidney failure, sometimes from a small amount.
Xylitol (sugar-free gum, candy, some peanut butters)	Sudden low blood sugar within 30 minutes to 2 hours, then possible liver failure.
Onions and garlic	Damage to red blood cells (anemia), sometimes days later.
Human medicines (painkillers, ADHD and heart drugs)	Varies — some are dangerous in a single tablet.
Rat and mouse poison, antifreeze, slug bait	Life-threatening. Some have antidotes if treated quickly.

Signs of poisoning to watch for

Vomiting, diarrhea, drooling, loss of appetite, tiredness, wobbliness, tremors, seizures, pale gums or unusual thirst. Signs can start within minutes or take a day or more to appear, so don’t rely on “they seem fine”.

At the vet

Depending on the poison, the vet may make your dog vomit safely, give activated charcoal, run blood tests, give IV fluids or an antidote, and keep your dog in for monitoring.

Frequently asked questions

How long after eating something toxic will a dog show symptoms?

It depends on the poison. Xylitol can cause signs within 30 minutes, while grape-related kidney damage may not show for 24–72 hours. Call for advice before symptoms appear.

Is it safe to give hydrogen peroxide to make my dog vomit?

Only if a vet or poison line tells you to, and only 3% hydrogen peroxide at the dose they give. Never use it for corrosive products or if your dog is already showing signs.

Does the poison helpline cost money?

ASPCA Animal Poison Control and Pet Poison Helpline may charge a consultation fee. Your own vet or an emergency clinic can also help.

What if I don’t know what my dog ate?

Call your vet anyway and bring any wrappers, plant pieces or vomit you find. Blood tests can help, though they can’t identify every poison.
