Many everyday foods in Canadian kitchens can be dangerous—even fatal—for dogs. Keep this quick, reliable list handy, and when in doubt, choose a dog-safe treat instead of sharing from your plate.

Common foods toxic to dogs (and why)

Chocolate (especially dark/baking): contains theobromine; causes vomiting, tremors, seizures.
Grapes & raisins: can trigger sudden kidney failure; even small amounts may be risky.
Onions, garlic, chives (raw, cooked, powdered): damage red blood cells; watch for weakness, pale gums.
Xylitol (in sugar-free gum, mints, some peanut butters, baked goods): causes dangerous low blood sugar and liver injury.
Alcohol (beer, wine, “spiked” desserts): depresses the nervous system; can lead to coma.
Coffee, tea, energy drinks (caffeine): agitation, high heart rate, tremors.
Macadamia nuts: weakness, vomiting, fever; symptoms can be dramatic.
Cooked bones (including rotisserie chicken bones): splintering can cause choking or gut perforation.
Fatty foods (bacon, pan drippings): can cause pancreatitis—painful and potentially severe.
Raw bread dough (yeast): expands in the stomach; can cause bloat and alcohol-like toxicity.
Avocado: may cause vomiting/diarrhea; the pit is a choking/obstruction hazard.
Salty snacks (chips, pretzels): can worsen dehydration and sodium issues, especially in small dogs.

Practical prevention tips for dog owners

Read labels: In Canada, xylitol may appear as “xylitol” on ingredient lists—avoid sharing any sugar-free product. Store safely: keep chocolate, gum, and baking supplies in closed cupboards. Be holiday-smart: Christmas baking, Thanksgiving leftovers, and BBQ scraps are peak risk times.

If your dog eats something toxic

Call your veterinarian or an emergency clinic immediately. If you’re in Canada, you can also contact the ASPCA Animal Poison Control (fee may apply). Don’t induce vomiting unless a professional tells you to—some toxins make it worse.

Bottom line: A little prevention goes a long way. When you want to share, stick to dog-safe options and keep this toxic foods list within reach.
