Others cause organ damage over 24–48 hours with no immediate symptoms. This is the complete guide to toxic foods for Australian dogs — including the hidden ones unique to our diet and environment.

Xylitol — The Hidden Killer in Australian Pantries
Even 1 teaspoon of xylitol can be lethal to a small dog
Xylitol triggers a massive insulin release in dogs, causing life-threatening hypoglycemia within 30–60 minutes. It's found in products most owners wouldn't suspect. Check ALL product labels before giving anything "sugar-free" to your dog — including peanut butter.
| Dog size | Toxic dose of xylitol | What contains that amount |
|---|---|---|
| 5 kg dog | 0.5 g | A few pieces of sugar-free gum |
| 10 kg dog | 1 g | One spoonful of some sugar-free peanut butters |
| 25 kg dog | 2.5 g | A small pack of Tic Tacs |
Grapes and Sultanas — Kidney Failure Risk
No safe amount — even 3–4 grapes can trigger kidney failure
Scientists don't yet fully understand the mechanism, but even small doses cause acute kidney injury in some dogs. A dog can eat grapes for years without issue and then suddenly develop kidney failure. There is no known safe threshold. Avoid completely.

Available 24/7, every day including public holidays. Have ready: the food name, estimated amount eaten, your dog's weight, and the time of ingestion. They'll tell you if emergency vet care is needed and whether to induce vomiting.
Go to the nearest emergency vet immediately if symptoms appear
Vomiting, lethargy, tremors, difficulty breathing, collapse, or seizures = emergency vet now. Don't wait to see if it gets worse. Do NOT induce vomiting unless specifically directed — for some toxins, vomiting makes it worse.
Bring what they ate (or a photo of the label)
The vet needs to know exactly what the toxin was. Bring the packaging, a photo of the ingredients list, or a description. Ingredient information determines the treatment protocol.
