Chocolate, grapes, sultanas, onions, garlic, xylitol and some other everyday foods can be toxic to dogs and cats. If your dog or cat has eaten something potentially harmful, it is important to seek veterinary advice promptly rather than waiting for symptoms to appear. The level of risk can depend on what was eaten, how much was consumed, your dog or cat’s size, and how long ago it happened.
For dog and cat owners in Ingleburn and surrounding areas, knowing which foods can be dangerous and what to do after a suspected poisoning can help you act quickly and seek appropriate veterinary care.
Common Foods That Can Be Toxic to Dogs and Cats
Dogs and cats can be surprisingly quick when food is dropped on the floor, left on a bench or forgotten in an open bag. Unfortunately, several foods we regularly keep at home can cause illness if eaten by them.
The Australian Animal Poisons Helpline’s guidance on common pet poisons identifies chocolate, grapes and dried grapes, onions, alcohol, caffeine and xylitol among potential household food hazards.
| Food | Why it can be dangerous | Possible warning signs |
| Chocolate and cocoa | Chocolate contains theobromine and caffeine. The risk varies depending on the type and amount of chocolate eaten and the size of your dog or cat. | Vomiting, diarrhoea, restlessness, tremors, increased heart rate or seizures |
| Grapes, raisins and sultanas | These can cause kidney injury in dogs. | Vomiting, loss of appetite, diarrhoea, lethargy or changes in thirst and urination |
| Onions, garlic, leeks and chives | Foods from the Allium family can damage red blood cells in dogs and cats. | Vomiting, weakness, pale gums, reduced appetite or rapid breathing |
| Xylitol | This sweetener can cause dangerously low blood sugar and potentially liver injury in dogs. | Vomiting, weakness, difficulty walking, collapse or seizures |
| Macadamia nuts | Macadamias can cause poisoning in dogs. | Weakness, vomiting, tremors, lethargy or difficulty walking |
| Alcohol and caffeine | These can have toxic effects on dogs and cats. | Agitation, weakness, tremors, vomiting or abnormal heart rate |
Not every exposure carries the same level of risk. For example, dark and baking chocolate contain considerably more of the compounds responsible for chocolate poisoning than milk chocolate. The Animal Poisons Helpline’s chocolate poisoning advice recommends seeking an individual risk assessment if your dog or cat has eaten chocolate.
Hidden Food Hazards Around the Home
Sometimes the dangerous ingredient is not obvious.
Grapes, raisins and sultanas can turn up in raisin toast, fruit cake, hot cross buns, muesli and other baked products. Dogs are particularly sensitive to these fruits, and kidney injury is possible after ingestion. The Australian guidance on grape and sultana poisoning advises owners not to wait for symptoms before seeking help.
Onions and garlic can also be hidden in cooked meals, sauces and seasoning mixes. If your dog or cat has eaten leftovers or prepared food, it is worth checking the complete ingredient list rather than focusing only on the main ingredients.
Sugar-free does not necessarily mean safe for dogs either. Xylitol, also known as birch sugar or E967, can be found in some sugar-free lollies, chewing gum, baked products, oral-care products and spreads. It can be particularly dangerous to dogs.
What Should You Do If Your Dog or Cat Eats Something Toxic?
First, prevent your dog or cat from eating any more of the food and check what they may have consumed.
If possible, make a note of:
- The food or product they ate
- Approximately how much is missing
- When they may have eaten it
- Your dog or cat’s approximate weight
- Any symptoms or unusual behaviour you have noticed
Keep the packaging or ingredient list if you still have it. This can provide useful information when you speak with a veterinarian or poison specialist.
Most importantly, do not try to make your dog or cat vomit or give them a home remedy unless a veterinary professional specifically tells you to do so. The appropriate response depends on what was consumed and the individual circumstances.
When Should You Contact a Veterinarian?
Do not assume everything is fine simply because your dog or cat appears normal immediately after eating something potentially toxic. Some effects can be delayed.
Seek veterinary advice promptly if you know or suspect your dog or cat has eaten a potentially dangerous food, particularly if you are unsure how much was consumed.
You should also seek veterinary attention if your dog or cat develops signs such as:
- Repeated vomiting or diarrhoea
- Unusual tiredness or weakness
- Tremors or difficulty walking
- Pale gums
- Changes in breathing
- An unusually fast or irregular heartbeat
- Collapse
- Seizures
- Changes in drinking or urination
For some exposures, veterinary advice is recommended even before symptoms develop. Grapes, raisins and sultanas are a good example because dogs can initially appear well despite the potential for kidney injury.
Why Acting Early After Suspected Food Poisoning Matters
There is no single treatment for every case of food poisoning. What your veterinarian recommends will depend on the food involved, the amount eaten, when it happened and the condition of your dog or cat.
This is why contacting a veterinary professional early is more useful than trying to decide at home whether an amount is “safe”.
A veterinary consultation allows your dog or cat’s individual situation to be assessed. If further investigation, monitoring or treatment is appropriate, your veterinarian can discuss the available options with you.
