Foods That Are Toxic to Dogs: A Comprehensive List

Many everyday foods in Canadian kitchens can seriously harm dogs—even in small amounts. Knowing what’s toxic (and what to do if your dog gets into it) can prevent an emergency trip to the vet. Use this list as a quick, reliable reference and share it with your household.

Common Toxic Foods (and Why They’re Dangerous)

Chocolate (especially dark/baking): Contains theobromine and caffeine; can cause vomiting, tremors, seizures, and heart issues.
Grapes and raisins: Can trigger sudden kidney failure; risk doesn’t depend on size or breed.
Onions, garlic, chives (all forms): Damage red blood cells and may cause anemia; includes powders and cooked foods.
Xylitol (birch sugar): Found in sugar-free gum/candy, some peanut butters, and baked goods; can cause rapid low blood sugar and liver failure.
Alcohol & raw yeast dough: Alcohol intoxication; dough can expand in the stomach and create dangerous bloat.
Macadamia nuts: Can cause weakness, wobbliness, vomiting, and fever.
Coffee, tea, energy drinks: Caffeine toxicity; restlessness, rapid heart rate, overheating.
Cooked bones: Splinter risk and intestinal blockage (not “toxic,” but a common severe hazard).
High-fat leftovers (bacon, gravy, fried foods): Can trigger pancreatitis; watch for vomiting and abdominal pain.
Some human meds/supplements: Especially ibuprofen, acetaminophen, and iron—store securely.

Actionable Safety Tips (Canada-Friendly)

Read labels on “sugar-free” products and peanut butter for xylitol. Secure compost bins (common in Canadian homes) and keep grapes/raisins out of reach, especially during holidays and baking season.

If your dog eats a toxic food, call your vet immediately. In Canada, you can also contact the ASPCA Animal Poison Control or Pet Poison Helpline (fees may apply). Don’t induce vomiting unless instructed.

Conclusion: Most poisoning cases are preventable. Keep risky foods locked away, train a solid “leave it,” and save your vet’s number in your phone—because fast action matters.
