If you're reading this because your dog or cat just ate something they shouldn't have, take a breath — and read the next two lines first. Do not try to make your pet vomit unless a vet tells you to. And call a vet or an animal poison line now, because the right response depends entirely on what was eaten, how much, and when. Then come back for the detail.
The first minutes genuinely matter with many poisons, and a calm, correct response beats a fast, wrong one.
Step 1: Get your pet away from it, safely
Move your pet away from whatever they were eating, and remove anything still in reach — without putting your hands at risk if your pet is frightened or guarding. If there's still some in the mouth and it's safe to do so, gently clear it. Keep any packaging, plant, or a sample of the substance.
Step 2: Call for help immediately
Phone your veterinarian or your nearest emergency clinic straight away. Give them:
- What was eaten (bring the packaging or a photo)
- How much — estimate generously (assume the worst-case amount)
- When it happened
- Your pet's weight, and any signs so far
They will tell you whether to come in immediately, whether to make your pet vomit (and how — never on your own initiative), or whether it can be monitored. With many toxins there's a time window where acting quickly changes everything; with others, vomiting would do more harm than good.
Step 3: What NOT to do
These well-meant mistakes can worsen the situation:
- Don't induce vomiting unless instructed. For corrosive substances (like drain cleaner) or petroleum products, vomiting causes further burns or lung damage. Old "home remedies" — salt, mustard — are unsafe and can poison your pet themselves. Hydrogen peroxide can seriously harm cats. Only make a pet vomit under veterinary direction [1].
- Don't give food, milk or any home remedy hoping to "dilute" it unless told to.
- Don't wait for symptoms. With several toxins, by the time signs appear the damage is advanced. Act on the exposure, not the symptoms.
- Don't give human medicines. Paracetamol (acetaminophen) is deadly to cats and dangerous to dogs; ibuprofen and other painkillers are toxic too.
The common toxins to know
Some everyday things are far more dangerous than owners expect:
- Chocolate (darker = more toxic), xylitol (in sugar-free gum, sweets, some peanut butters — causes a rapid, dangerous blood-sugar crash and liver injury in dogs), grapes and raisins (kidney failure), onions and garlic, and macadamia nuts — see the full list in foods that are toxic to pets
- Lilies — even a nibble of leaf, petal, pollen or the vase water can cause fatal kidney failure in cats; treat any exposure as an emergency [2]
- Human medicines — painkillers, antidepressants, ADHD medication
- Household and garden products — antifreeze (a tiny amount is lethal and it tastes sweet), rodent bait, insecticides, some cleaning products
- Certain plants and, for some pets, grapes, alcohol, and caffeine
While you're on the way
Bring the packaging, plant or a sample, and a note of the time and estimated amount. Keep your pet calm and, if it's safe, bring a fresh sample of any vomit — it can help the vet. Drive safely; a few minutes of careful driving is worth more than a rushed accident.
The bottom line
Pet poisoning is one of the situations where the default instinct — make them sick, wait and see — is often exactly wrong. The reliably right first moves are simpler: get your pet away from the toxin, call a vet or poison line immediately with the what/how-much/when, and follow their instructions rather than the internet's. Prevention beats all of it — but if it's already happened, a fast phone call is the best thing you can do.
Frequently asked questions
Should I make my dog throw up if they ate something toxic? Not on your own. For some toxins vomiting helps; for corrosives, petroleum products, and in cats especially, it causes serious harm. Home methods like salt or hydrogen peroxide can poison your pet themselves. Always call a vet or poison line first and only induce vomiting under their direction [1].
My dog ate chocolate — what should I do? Call your vet now with the type of chocolate (dark is most toxic), the amount, your dog's weight, and the time. They'll advise based on the dose whether to come in. Don't wait for symptoms, and don't try home remedies.
My cat brushed against or ate a lily — is that serious? Yes — lilies are extremely toxic to cats, and even pollen, a nibbled leaf, or the vase water can cause fatal kidney failure. Treat any lily exposure as an emergency and get to a vet immediately [2].
How long do I have to act after my pet eats a toxin? It varies by poison, but sooner is almost always better — with many toxins there's an early window where treatment prevents damage that later becomes irreversible. Don't wait for signs; call the moment you know or suspect exposure.
