Foods Toxic to Dogs: A Singapore Pawrent's Danger List

Picture a typical Singapore evening. The family is unwrapping bak kwa, someone is prying open a durian, and a hopeful pair of eyes is parked right under the table. Our furkids are professional beggars, and we love them for it. The problem is that a lot of the food we happily share is, at best, a tummy ache waiting to happen, and at worst, a genuine emergency.

The tricky part is that "toxic" is not always obvious. A grape looks harmless. A square of dark chocolate seems like a tiny treat. A lick of sugar-free peanut butter feels generous. But for a dog, some of these can mean a midnight dash to the emergency vet, or far worse. Singapore adds its own twist, because our festive seasons and hawker favourites bring foods you will not find on most overseas danger lists.

So here is your pawrent's danger list: the global toxic foods every dog owner should know, plus the local ones we actually run into here. We have checked the toxicity facts against the ASPCA Animal Poison Control Center and reputable vet sources, and we have been honest where the science is debated. Let's keep our furkids safe. ❤️

The core toxic list (and why each one is dangerous)

These are the foods that show up on poison-control lists worldwide. Keep them well out of reach.

• Chocolate (theobromine and caffeine): Dogs cannot break down theobromine the way we can. It can cause vomiting, racing heart, tremors, seizures and even death. Danger level: high. Darker and more bitter (baking chocolate, 70% dark) is far more dangerous than milk chocolate. 🚫
• Grapes and raisins: Can cause sudden kidney failure, and even a small amount can do it. The current leading theory points to tartaric acid, which dogs struggle to process. Danger level: high and unpredictable. There is no known "safe" dose, so treat all grapes, raisins and sultanas as off-limits.
• Onion, garlic, chives and leeks (the allium family): These damage red blood cells and can lead to anaemia. Danger level: moderate to high, and it builds up. Cooked, raw, or powdered all count, which is why gravies, marinades and stocks are a hidden risk.
• Xylitol / birch sugar: A sweetener hiding in sugar-free gum, mints, some peanut butters and certain "no sugar" baked goods. It can trigger a dangerous blood-sugar crash (hypoglycaemia) and liver damage. Danger level: very high, very fast. Always check peanut butter labels before sharing.
• Macadamia nuts: Can cause weakness, wobbly legs, vomiting, tremors and a raised body temperature, usually within 12 hours. Danger level: moderate. Most dogs recover, but it is a miserable and scary experience.
• Alcohol: Even small amounts can cause vomiting, breathing trouble, dangerous drops in body temperature and blood sugar, and coma. Danger level: high. This includes uncooked dough and anything fermenting (see yeast dough below).
• Caffeine (coffee, tea, energy drinks): Same family of stimulants as chocolate. Coffee grounds, tea bags and that leftover kopi are all risky. Danger level: high.
• Raw yeast bread dough: A double threat. The dough keeps rising in the warm stomach, causing painful bloating and a risk of dangerous twisting, and the fermenting yeast produces alcohol. Danger level: high.
• Excessive salt: Too much salt can cause vomiting, tremors and seizures. Danger level: depends on dose, but salty human snacks (chips, salted nuts, cured meats) add up fast in a small body.
• Cooked bones: Not a "toxin", but a real hazard. Cooked bones turn brittle and splinter, which can puncture the gut or cause a blockage. Danger level: high for the physical risk. Keep all cooked bones, including chicken bones, away.
• Avocado (the honest version): This one is genuinely debated. Avocado contains persin, but dogs are much less sensitive to it than birds or livestock, and there are no confirmed cases of persin killing a dog. The bigger, real-world risks are the high fat content (which can trigger pancreatitis) and the large pit, which can cause a choking or intestinal blockage. Verdict: not the deadly poison some lists claim, but not a great idea either. 🥑

Singapore's local danger foods 🇸🇬

Here is where most overseas guides go quiet. These are the treats our furkids are most likely to encounter at home, at gatherings, or on a kopitiam table.

Durian

The flesh is not classically "toxic", and a tiny taste is unlikely to poison your dog. But it is very high in sugar and fat, which can upset the stomach or, over time, contribute to pancreatitis in sensitive dogs. The real danger is the seed: it is a serious choking and intestinal-obstruction hazard. We have a full deep-dive on durian and other local foods if you want the details: Can dogs eat durian and other Singapore local foods.

Mooncakes

Festive but risky. Mooncakes are very high in sugar and fat (rough on the pancreas), the lotus and red bean fillings add even more sugar, and some "low sugar" or "sugar-free" versions may contain xylitol, which is the genuinely dangerous one. Chocolate-flavoured or chocolate-coated mooncakes carry the chocolate risk too. Keep the whole tin out of reach during Mid-Autumn.

Bak kwa

That irresistible Chinese New Year barbecued pork is loaded with salt and sugar, and often glazed with soy and other seasonings. The high salt and fat make it a poor (and potentially harmful) treat, especially in large amounts. A begging furkid plus a full tray of bak kwa is a recipe for an upset, dehydrated dog.

Satay

Triple trouble. The marinade usually contains onion and garlic (allium toxicity), the peanut sauce is high in fat and sometimes sugar, and the wooden skewer is a sharp obstruction and puncture hazard. Never let a dog grab a satay stick.

Chicken bones from local food

Hainanese chicken rice, roast chicken, soup bones. These are cooked, so they splinter. Cooked chicken bones are one of the most common causes of emergency vet visits here. Plain, deboned cooked chicken is fine; the bones are not.

Festive chocolate and baking

Christmas and Easter mean more chocolate in the house, and festive baking often means raisins, sultanas and currants in fruit cakes and cookies. Both are on the high-danger list. Keep gift boxes and baking ingredients somewhere your furkid genuinely cannot reach.

What to do in an emergency 🚨

If you know or even suspect your dog has eaten something toxic, treat it as urgent. Many of these poisons cause the most damage in the first few hours, so the worst thing you can do is "wait and see".

Signs of poisoning to watch for

• Vomiting or diarrhoea (sometimes with blood)
• Drooling, or trying to vomit without bringing anything up
• Wobbliness, weakness, or trouble standing
• Tremors, twitching or seizures
• Racing heart, heavy panting or breathing difficulty
• Extreme lethargy, collapse, or sudden behaviour changes
• Drinking or urinating a lot more than usual (a warning sign with grapes and raisins)

Important: with several of these poisons, your dog can look completely normal at first and then crash later. Do not let a calm-looking furkid talk you out of calling the vet.

Your emergency steps

• Remove the food immediately so no more is eaten, and keep the packaging.
• Note three things: what was eaten, roughly how much, and what time. This helps the vet decide how to treat.
• Call a 24-hour emergency vet right away and follow their instructions. If you are unsure which clinic to use, our guide on choosing the right vet in Singapore is a good place to start (save an emergency number in your phone today).
• Do not induce vomiting unless a vet tells you to. With some substances it can make things much worse.
• Go in. If in doubt, get seen. It is always better to be the pawrent who "overreacted" than the one who waited too long.

The everyday way to take the guesswork out

Most toxic-food scares happen by accident: a dropped grape, a stolen satay stick, a "harmless" lick of someone's snack. You cannot childproof the whole world, but you can make your dog's actual meals boring in the best possible way. A simple, fresh, single-protein meal means you always know exactly what is going into your furkid, with no hidden onion powder, no mystery sweeteners, no surprise seasoning.

That is the whole idea behind our gently cooked food: single proteins, sous vide at 80°C, PhD-formulated to AAFCO All Life Stages, with the full recipes published openly on our formulas page so you can read every ingredient. If you would like to see how your dog takes to it, the gently cooked trial packs are an easy, low-commitment way to start. No hard sell. Just real food you can actually pronounce. 🐶

And if you ever notice a sensitive tummy when switching things up, our guide on solving pet diarrhea and when to change food walks you through it gently.

Frequently asked questions

How much chocolate is dangerous for my dog?

It depends on the type of chocolate and your dog's size. Darker, more bitter chocolate (baking and dark chocolate) has far more theobromine than milk chocolate, so even a small amount can be serious for a small dog. Because the safe threshold is so variable, do not try to calculate it yourself. If your dog has eaten any chocolate, call a 24-hour emergency vet with the type, amount and your dog's weight ready.

Can my dog eat durian flesh in Singapore?

A tiny taste of the flesh is unlikely to poison your dog, and durian is not "toxic" in the classic sense. But it is very high in sugar and fat, which can cause stomach upset or contribute to pancreatitis in sensitive dogs, and the seed is a serious choking and obstruction hazard. We would keep it as a rare, tiny treat at most, and never let your dog near the seed. There is more detail in our durian deep-dive.

Is xylitol really in peanut butter?

It can be. Some "sugar-free", "no added sugar" or diet peanut butters use xylitol (also labelled as birch sugar) as a sweetener, and even a small amount can be dangerous for dogs. Always read the ingredient list before sharing peanut butter, and if you are unsure, do not risk it. Plain peanut butter with no xylitol and no added salt is the safer choice.

My dog ate something toxic but seems totally fine. Do I still call the vet?

Yes. With several poisons, including grapes, raisins and xylitol, your dog can look perfectly normal for hours before serious symptoms appear, and the early window is often when treatment works best. Do not wait for symptoms. Call a 24-hour emergency vet straight away with the food, amount and time, and follow their advice.
