Foods That Are Toxic to Dogs: A Comprehensive List

Dogs beg. We share. But some everyday foods can cause serious poisoning—sometimes with only a small amount. In Canada, the risks spike around holidays (Thanksgiving, Christmas, Easter) when rich foods and baking ingredients are everywhere. Use this checklist to dog-proof your kitchen and snack smarter.

Common Toxic Foods (and What They Do)

Chocolate (especially dark/baking): Theobromine can trigger vomiting, tremors, seizures, and heart issues.
Grapes & raisins: Can cause sudden kidney failure—no “safe” dose is known.
Onions, garlic, chives (raw, cooked, powdered): Damage red blood cells; watch soups, seasonings, and baby food.
Xylitol (in sugar-free gum/candy, some peanut butters, “keto” snacks): Can cause dangerous low blood sugar and liver failure.
Alcohol: Even small sips can lead to severe intoxication, low temperature, and coma.
Coffee, tea, energy drinks: Caffeine causes agitation, rapid heart rate, and seizures.
Macadamia nuts: Weakness, vomiting, tremors; symptoms can appear within hours.
Cooked bones (chicken, turkey, ribs): Splinter risk; can cause choking, obstructions, or perforations.
Fatty foods (bacon, gravy, fried foods): Can trigger pancreatitis—painful and potentially serious.
Raw bread dough: Expands in the stomach and can produce alcohol during fermentation.

What to Do If Your Dog Eats Something Toxic

Act fast. Remove access, note the amount/time, and keep packaging. Don’t induce vomiting unless a vet tells you to.

In Canada, call your veterinarian or an emergency clinic right away; many also recommend contacting Pet Poison Helpline for immediate guidance (fees may apply).

Prevention tips: store baking supplies high up, choose xylitol-free peanut butter, keep garbage secured, and teach a solid “leave it.”

Bottom line: When in doubt, don’t share. A quick call can save your dog’s life.
