Foods dogs should not eat can hide in everyday meals, from onion powder in gravy to raisins in fruit loaf.
Checking individual ingredients matters when sharing leftovers or making homemade treats, says pet product development specialist Elizabeth Freeland.
Freeland is Senior R&D Technologist at Australian dog-food company Eureka Pet Co.
“The pattern I see is rarely someone deliberately feeding something toxic,” she says.
“It’s an ingredient hiding inside a recipe, a sauce, a marinade or a baked good that the owner hasn’t cross-checked.”
Has your dog already eaten something harmful?
Call your vet immediately. Do not wait for symptoms. In Australia, the Animal Poisons Helpline is available on 1300 869 738.
Keep the packaging. Note what your dog ate, roughly how much and when, and provide your dog’s weight.
Do not induce vomiting or give food, drinks or home remedies unless a vet or poisons specialist advises it.
Six foods and ingredients to keep away from dogs
This is a practical checklist of common hazards, not a complete list of everything that can harm dogs.
1. Onion and garlic
Raw, cooked, dried and powdered forms can damage red blood cells. Gravy, stock, pasta sauce and marinades may contain them.
“These damage red blood cells, and the effect is cumulative. The powdered forms are easy to miss in gravies, stocks, sauces and leftovers,” Freeland says.
A single exposure can also cause poisoning; repeated feeding is not required. Contact your vet rather than judging safety by appearance.
2. Grapes, raisins and sultanas
These can cause kidney injury in dogs. Check fruit loaf, hot cross buns, trail mix and Christmas pudding.
“They can cause acute kidney injury in some dogs, even in small amounts,” Freeland says.
There is no reliable safe amount to use at home. Seek advice even if your dog seems well.
3. Xylitol
This sweetener can cause a rapid fall in blood sugar and liver injury in dogs.
Check sugar-free chewing gum, sweets, baked goods and some peanut butters. Not every sugar-free product contains xylitol.
Read the ingredient list before using peanut butter in a treat or food puzzle.
4. Macadamia nuts
Macadamias can cause weakness, vomiting, tremors and increased body temperature. Keep nuts, biscuits and cakes containing them out of reach.
5. Chocolate and caffeine
The risk depends on the product, amount eaten and dog’s weight. Dark chocolate, baking chocolate and cocoa powder are particularly concentrated.
Coffee, caffeine-containing drinks and supplements are also hazards. Keep the product details for your vet.
6. Cooked bones
Roast chicken carcasses and cooked chop bones can cause choking, obstruction or injuries to the digestive tract.
They are physical hazards rather than poisons. Raw bones also carry risks, including injury, obstruction and bacterial contamination.
Check these before sharing leftovers
- Sauces and stocks: Look for onion, garlic and their powdered forms.
- Peanut butter and sweeteners: Check specifically for xylitol.
- Fruit breads and cakes: Check for raisins, sultanas, grapes, chocolate and macadamias.
- Roast dinners and barbecue scraps: Remove access to bones, skewers and food packaging.
- Bins and kitchen benches: Clear leftovers before your dog can reach them.
“Pastry, sugar or a ‘healthier’ sweetener swap can undo an otherwise sensible base, so check the real ingredient list, not the title,” Freeland says.
What to do if your dog eats toxic food
“If you suspect your dog has eaten something toxic, don’t wait for symptoms. Call your vet straight away,” Freeland says.
“Note what they ate, roughly how much and when, and keep the packaging if you have it. That’s the information your vet will need first, and it can make a real difference to how quickly they can act.”
For immediate concerns, contact your vet or the Animal Poisons Helpline using the details above.
