Toxic Foods for Cats and Dogs

Pets have a way of getting into things they shouldn’t — especially when it comes to food. But not all human treats are safe for furry companions. Some can cause serious illness or even be life-threatening. If your dog or cat ate a toxin or something questionable, don’t wait — call your vet or the Animal Poisons Helpline for advice. Here’s a guide to help you spot problems early and know when to act.

1. My dog or cat ate chocolate — do I need to see the vet?

Yes. Chocolate contains theobromine and caffeine, both of which are toxic to dogs and cats. The darker the chocolate, the more dangerous it is. If your dog ate chocolate or your cat got into cocoa, contact your emergency vet immediately.

How much chocolate is okay?

There is no safe amount, but the risk depends on your pet’s weight, the type of chocolate, and how much was eaten. Use our chocolate toxicity calculator below, or call your vet with the details.

Chocolate poisoning symptoms

  • Vomiting or diarrhoea
  • Hyperactivity or restlessness
  • Tremors or seizures
  • Fast heart rate

Chocolate Toxicity Calculator for Dogs

Estimate if your dog is at risk after eating chocolate. For emergencies, contact MediPaws immediately.

2. Grapes and raisins

If your dog or cat ate grapes or raisins, this is an emergency. These can cause kidney failure, and not all pets are affected the same way.

Symptoms to watch for

  • Vomiting within hours
  • Lethargy
  • Loss of appetite
  • Increased thirst or urination

Don’t wait for symptoms. Seek help right away.

3. Xylitol and dogs

Xylitol is a sugar substitute found in gum, peanut butter, lollies, baked goods, and even some toothpastes. In dogs, it causes a rapid drop in blood sugar and can lead to liver failure.

Early signs

  • Vomiting
  • Weakness or collapse
  • Seizures

Xylitol and dogs do not mix. If you’re worried your dog ate xylitol, get to your emergency vet without delay.

4. Other toxic foods to dogs and cats

  • Onions, garlic, and chives
  • Alcohol
  • Macadamia nuts
  • Cooked bones (risk of obstruction or perforation)
  • Yeast dough
  • Fatty table scraps

What to do if your pet ate something poisonous

  1. Stay calm but act quickly.
  2. Don’t try to induce vomiting unless advised.
  3. Keep the packaging (or take a photo of it).
  4. Call your local emergency vet or the Animal Poisons Helpline (Australia: 1300 869 738).
