Dog Poisoning: Toxic Foods, Symptoms and First Steps
If your dog has just eaten something you think may be toxic, call your vet or an animal poison control line now, before symptoms appear, not after. Many poisonings are far easier and cheaper to treat in the first hour or two. Everything else on this page can wait until you have made that call.

The first five minutes
Move your dog away from the source and pick up anything left so no other pet can reach it. Keep the packaging, wrapper or a sample of the plant: the exact product, its strength and how much is missing are what a vet needs to work out whether the dose is dangerous.
Then phone. Your own vet or the nearest emergency clinic is the first call. In the US, the ASPCA Animal Poison Control Center (888-426-4435) and the Pet Poison Helpline (855-764-7661) are staffed around the clock by veterinary toxicology specialists, and both charge a consultation fee. Have your dog’s weight to hand.
Do not make your dog vomit unless a vet tells you to. Some substances (caustics, petroleum products, sharp objects) do more harm coming back up, vomiting is risky for a drowsy dog, and home methods such as salt are themselves dangerous.
The household toxins vets see most
Most canine poisonings involve ordinary things already in the house. The list below covers the ones that come up most often and what they do. Amounts matter for some (chocolate is dose-dependent) and barely at all for others (with grapes and raisins there is no known safe amount).
| Toxin | Found in | Main danger |
|---|---|---|
| Theobromine | Chocolate, cocoa, baking chocolate | Vomiting, racing heart, tremors, seizures |
| Unknown toxin (tartaric acid suspected) | Grapes, raisins, sultanas, currants | Sudden kidney injury |
| Xylitol | Sugar-free gum, some peanut butters, sweets | Severe low blood sugar, liver failure |
| Thiosulfates | Onions, garlic, leeks, chives | Damage to red blood cells (anemia) |
| NSAIDs | Ibuprofen, naproxen | Stomach ulcers, kidney injury |
| Acetaminophen | Tylenol / paracetamol | Liver damage, red blood cell damage |
| Anticoagulant rodenticides | Many rat and mouse baits | Internal bleeding, often days later |
| Ethylene glycol | Antifreeze, some coolants | Kidney failure, and treatment is time-critical |
Signs of poisoning
Signs depend entirely on the toxin, and some (rat bait, grapes, antifreeze) can take hours or days to show while the damage is already happening. That is why waiting for symptoms is the wrong approach when you know your dog ate something.
Signs that should send you to a vet straight away include vomiting or diarrhea after access to something toxic, drooling, wobbliness or stumbling, tremors or seizures, unusual agitation or sleepiness, a racing heart, pale gums, bleeding or bruising, and collapse.
Common questions
Is it safe to make my dog throw up at home?
Only if a vet or poison control specialist tells you to, and only by the method they give you. Inducing vomiting is the wrong move for some poisons, for dogs that are already drowsy or having trouble breathing, and after too much time has passed. Salt, mustard and fingers down the throat are unsafe and should never be used.
How long after eating something toxic will a dog show symptoms?
It varies from minutes to days. Xylitol can cause low blood sugar within an hour, chocolate typically within 6 to 12 hours, while anticoagulant rat baits and grape-related kidney injury can take one to several days to show. Treatment works best before signs appear, so call as soon as you know about the exposure.
What information will the vet or poison line ask for?
Your dog’s weight, age and any health conditions. What was eaten, including the product name and strength from the packaging. Roughly how much is missing, when it happened, and any signs you have seen since. Having these ready makes the call faster and the advice more precise.
