Foods Dogs Should Never Eat

Published 2026-11-02 · PawAtlas

Grapes and raisins

These can cause sudden kidney failure in dogs, even in small amounts.

Chocolate

Theobromine and caffeine in chocolate can cause vomiting, tremors and seizures. Dark chocolate is the most dangerous.

Onions, garlic and chives

These damage red blood cells and can cause anemia.

Xylitol and macadamia nuts

Xylitol, found in sugar-free products, can cause a sudden drop in blood sugar and liver failure. Macadamia nuts can cause weakness and tremors.

What to do

If your dog eats something toxic, contact a vet or poison helpline immediately instead of waiting for symptoms.
