My dog ate something toxic: what to do right now
Reviewed against ASPCA, VCA Animal Hospitals, the Merck Veterinary Manual and AVMA material. Last updated 5 October 2026.
This is the only one of the 15 signs in our dog check with no watch level and no red flags to tick. Suspected poisoning is an emergency from the start, even if your dog looks completely fine. Call your vet or a poison line now. Several of these substances act before a dog shows anything.
Call now
Your own vet or the nearest emergency animal hospital is the first call. If you cannot reach one, the US poison lines run around the clock. A fee may apply to both.
- ASPCA Animal Poison Control: (888) 426-4435 — available 24 hours a day, 365 days a year, per the ASPCA.
- Pet Poison Helpline: (855) 764-7661
Have these four things ready before you dial.
- What I ate, how much, and when
- Keep the packaging or a photo of the label
- My weight
- Any vomiting, shaking or wobbliness
Urgency table: suspected poisoning
| What you see | How fast | Source |
|---|---|---|
| Your dog ate, or may have eaten, anything on the list below — even if they look fine | Vet now | ASPCA |
| Struggling to breathe, or gums look pale, white, blue or gray | Vet now | AVMA |
| Collapsed, can't stand up, or is unusually unresponsive | Vet now | AVMA |
| Having or just had a seizure (stiff body, paddling legs, not responding) | Vet now | VCA, seizures |
| In severe pain: crying out, or can't get comfortable | Vet now | AVMA |
The list in our check
These are the seven items the dog check names, taken from its own published data:
- Grapes, raisins, currants
- Chocolate and cocoa
- Xylitol (sugar-free gum, sweets, some peanut butters)
- Onions, garlic, chives, leeks
- Human medications
- Macadamia nuts, alcohol, raw bread dough
- Antifreeze, rat or slug poison
The ASPCA's own page of people foods to avoid also names coffee and caffeine, dairy, nuts, salt, citrus, coconut, and raw meat, eggs and bones. The sources below link the full page, and the ASPCA plant list for anything chewed in the garden.
Why "he looks fine" is not reassurance
Each of these has a published reason for being on the list. We are not telling you how bad your dog's case is — that is the call you are about to make — but the timings explain why waiting is wrong.
- Grapes, raisins and currants. VCA Animal Hospitals says there is no well-established toxic dose and that some dogs may be poisoned by even a small amount, seeded or seedless, red or green. It puts the earliest sign, vomiting or diarrhoea, at 12 to 24 hours, with more severe signs often not appearing until 24 to 48 hours — by which point, it notes, kidney damage may already have begun.
- Chocolate. VCA says signs can take several hours to develop and last for several days, and that the dose is calculated from the amount and type eaten. It ranks cocoa beans and unsweetened cocoa powder highest for theobromine, with milk and white chocolate lowest. That means "a square of chocolate" is not a useful description — the type and weight are.
- Xylitol. The Merck Veterinary Manual notes dogs are the only domestic species in which xylitol toxicosis has been reported, and that signs of low blood sugar can appear within 30 minutes but may be delayed up to 12 to 18 hours when the xylitol is in something that slows absorption, such as some gums. VCA adds that it turns up far beyond gum: oral care products, nasal sprays, laxatives, allergy medicines, supplements and prescription human medicines, especially quick-dissolve tablets and liquids.
- Onions, garlic, chives and leeks. VCA says these are a common cause of poisoning in dogs, with garlic the most toxic of the group, and gives a figure worth remembering in a kitchen: one teaspoon of garlic powder is equivalent to about eight cloves of fresh garlic.
- Raw bread dough. The ASPCA says yeast dough can rise and cause gas to build up in the digestive system, potentially bloating and twisting the stomach, which it calls a life-threatening emergency, and that the yeast also produces alcohol in the stomach.
What not to do
- Don't make your dog vomit on your own initiative. AVMA's first-aid guidance is to always contact your veterinarian or a poison control center before inducing vomiting. This page gives no method, no product and no dose for it.
- Don't give anything else by mouth — milk, food, charcoal, salt, oil — unless the vet or the poison line tells you to. AVMA lists activated charcoal as a kit item to use only if instructed by a veterinarian or poison control center.
- Don't throw the packaging away. It carries the one thing nobody can reconstruct later.
- Don't wait for symptoms, and don't drive without calling first. AVMA's advice for an emergency is to call your veterinarian or local veterinary emergency hospital so they can be ready when you arrive.
Check your dog in one minute
If you are not sure this is the right sign — if what you see is shaking, vomiting or sudden lethargy and you only suspect something was eaten — the free check sorts it in under a minute. No email needed. It will not tell you to wait.
Questions
My dog ate chocolate but seems fine. Do I still call?
Yes. VCA Animal Hospitals says signs of chocolate poisoning can take several hours to develop and can last for several days, and that the dose is calculated from the amount and type of chocolate eaten. Looking fine an hour later isn't information that rules anything out. Call your vet or a poison line and let them do the arithmetic.
How much is a dangerous amount?
That is exactly what a poison line works out, and it is why this page gives no amounts. For grapes and raisins VCA Animal Hospitals states there is no well-established toxic dose and that some dogs may be poisoned by even a small amount. For chocolate, the darker and more bitter it is, the more dangerous. Weight, product and quantity all change the answer, so hand those three facts to a professional.
Should I make my dog vomit?
Not on your own initiative. AVMA's first-aid guidance is to always contact your veterinarian or a poison control center before inducing vomiting. This page gives no instructions for doing it, no products and no doses. Make the call and follow what the vet or the poison line tells you.
What this page doesn't do
- It doesn't tell you whether your dog ate a dangerous amount. Only a vet or a poison line can judge that, from the product, the quantity and your dog's weight.
- It gives no treatment, no doses, no antidotes, and no method for making a dog vomit at home.
- No vet wrote or reviewed it. It is a published rule set with a named source per line, assembled by Guides Daily.
- It is not a substitute for the call. If you have read this far and have not phoned anyone, stop reading and phone.
