While you are spending time at home cooking up a storm in the kitchen, you might be tempted to share your human food with your dog. However, there are foods that are not safe for your dog to consume.

Here is a list of common foods to avoid in order to protect your dog’s health.


Chocolate contains a theobromine and caffeine, which are toxic to dogs. Ingesting chocolate can cause digestive, neurological and cardiac problems for your dog.

Grapes, Raisins & Sultanas

Many people don’t realise that grapes, raisins and sultanas are toxic to dogs. This includes both raw and cooked forms, so you should also avoid any baked treats or muesli bars that contain these foods. The active ingredient which causes the toxicity is unknown, however, ingesting as little as one grape, raisin or sultana can potentially cause fatal kidney damage.

Corn on the Cob

Many dogs love to chew on corn on the cob, the problem is that dogs can eat either the entire cob or large pieces of it. This can cause intestinal obstruction, a serious and potentially fatal condition that may require emergency surgery.

Cooked Bones

Cooked bones can be quite dangerous for dogs. This is because bones often splinter, and when that happens, the sharp pieces can rupture your dog’s digestive tract. Keep in mind that even raw bones can cause life-threatening oesophageal and gastrointestinal obstruction.

Macadamia Nuts

Macadamia nuts are a popular snack in Australia, but did you know they can be poisonous to dogs? These nuts can cause neurological problems such as weakness and tremors.


Dogs are more sensitive to the effects of caffeine than people are. The ingestion of coffee , tea, energy drinks and even chocolate can cause severe poisoning.


Alcohol is toxic to dogs. Both the ethanol in beer, wine and liquor and the hops used to brew beer can cause dogs to suffer dangerous alcohol intoxication.

If you are concerned that your dog has ingested any of these foods, or any other foods that you are unsure of, please contact your vet straight away. The earlier treatment is initiated, the better the chances that your pet will recover.

What should you feed your dog instead?

A dog’s nutritional needs are very different to ours, and there are specific nutrients that they need in order to prevent serious health problems. Read these tips on how to provide a balanced diet for your pet.
