Foods That Are Toxic to Dogs
Many everyday foods that are completely safe for humans can be seriously harmful, even life-threatening, to dogs. This isn't an exhaustive medical guide, but it covers the most common toxic foods every dog owner should know to keep out of reach.
Chocolate
Chocolate contains theobromine, which dogs metabolize far more slowly than humans do, allowing it to build up to toxic levels. Darker, more concentrated chocolate (baking chocolate, dark chocolate) is more dangerous than milk chocolate for a given amount, but all forms pose some risk.
Grapes and raisins
Grapes and raisins can cause sudden kidney failure in some dogs, and unlike many toxins, the dangerous dose isn't well established or consistent between individual dogs. Because of this unpredictability, they're best avoided entirely regardless of the dog's size.
Onions, garlic, and chives
Members of the allium family damage red blood cells in dogs and can cause anemia. This includes onion and garlic powder, which are easy to overlook in cooked foods, sauces, and seasoning blends.
Xylitol
This sugar substitute, found in sugar-free gum, some peanut butters, and baked goods, causes a rapid and dangerous drop in blood sugar in dogs, along with potential liver damage. Always check ingredient labels on sugar-free products before sharing with a dog.
Alcohol and raw yeast dough
Alcohol affects dogs much like it affects humans but at far lower doses relative to body weight. Raw bread dough is a separate risk: it can continue rising in a dog's warm stomach, causing painful bloating, and the fermentation process produces alcohol as a byproduct.
Frequently asked questions
What should I do if my dog eats something toxic?
Contact your vet or an animal poison control hotline immediately, and have information ready about what was eaten, how much, and when. Don't induce vomiting unless specifically instructed to by a professional, since this can make some situations worse.
Is peanut butter safe for dogs?
Most peanut butter is safe in moderation, but always check the label first, since some brands use xylitol as a sweetener, which is toxic to dogs.
How much chocolate is dangerous for a dog?
It depends on the dog's size and the type of chocolate; darker chocolate is more concentrated and dangerous in smaller amounts. Given the variability, it's safest to contact a vet anytime a dog eats chocolate rather than trying to estimate a safe threshold yourself.
