Foods that are toxic to dogs
Many foods that are perfectly safe for us can make dogs seriously ill. Some of the most dangerous are found in almost every kitchen.
The most dangerous
Chocolate
Contains theobromine, which dogs process very slowly. Dark, cooking and cocoa-rich chocolate are the most dangerous. Signs include vomiting, restlessness, a racing heart, tremors and seizures.
Grapes, raisins, sultanas and currants
Can cause sudden kidney failure, and there is no known safe amount. Watch out for hot cross buns, fruit cake, mince pies, cereal bars and trail mix.
Xylitol
A sweetener in sugar-free gum, sweets, some peanut butters, baked goods and toothpaste. It causes a dangerous drop in blood sugar and can damage the liver.
Onions, garlic, leeks and chives
Raw, cooked or powdered, these damage red blood cells and cause anaemia. Effects can build up over several days. Check gravies, stocks and ready meals.
Also harmful
- Macadamia nuts: weakness, wobbliness and fever.
- Alcohol and raw bread dough: dough can expand in the stomach and produce alcohol.
- Caffeine: coffee, tea bags, energy drinks and caffeine tablets.
- Cooked bones: splinter and can cause choking, tears and blockages. See our bones guide.
- Corn on the cob, fruit stones and avocado stones: common causes of gut blockages.
- Very fatty foods: can trigger painful pancreatitis.
- Mouldy food from bins or compost: can cause tremors and seizures.
Prevention
Store food out of reach, use a dog-proof bin, keep handbags off the floor (gum and medicines are common finds), and make sure visitors and children know the rules.
When to contact your vet
- Your dog has eaten any of the foods above. Call immediately, even if they seem well, as many poisons take hours to show. Have the packaging to hand.
Not registered with a vet, or need one out of hours? See our local vets near Horley.
