Some human foods are genuinely toxic to dogs; others are dangerous because they can cause obstruction, severe digestive upset, pancreatitis, or other complications. If your dog eats something questionable, the safest response depends on the food, amount, and your dog’s size and health.
1. Chocolate and cocoa
Chocolate contains methylxanthines such as theobromine and caffeine. Dark chocolate, baking chocolate, and cocoa powder generally pose greater risk than products with less cocoa.
2. Grapes and raisins
Grapes and raisins can cause acute kidney injury in dogs, and a reliably safe dose has not been established. Treat any ingestion as a reason to contact a veterinarian or animal poison service promptly.
3. Xylitol
Xylitol, a sweetener found in some sugar-free gum, candy, baked goods, toothpaste, peanut or nut butters, and other products, can cause a dangerous drop in blood sugar and may cause liver injury. This is an emergency exposure.
4. Onions, garlic, chives, and leeks
Members of the allium family can damage red blood cells and cause anemia. Risk depends on the amount and form, including powders and concentrated seasonings.
5. Alcohol
Alcoholic drinks and alcohol-containing foods can cause serious intoxication. Keep cocktails, fermented products, and alcohol-containing desserts out of reach.
6. Coffee and other concentrated caffeine
Coffee grounds, beans, energy products, caffeine tablets, and other concentrated sources can cause agitation, abnormal heart rhythms, tremors, seizures, and other serious signs.
7. Raw yeast dough
Unbaked yeast dough can expand in the stomach and may produce alcohol as it ferments. Both the expansion and alcohol exposure can be dangerous.
8. Macadamia nuts
Macadamia nuts can cause weakness, poor coordination, vomiting, tremors, and elevated body temperature in dogs.
9. Moldy food and compost
Moldy foods and compost can contain toxins capable of causing severe tremors or seizures. Secure trash and compost where dogs cannot reach them.
10. Fruit pits, stones, and certain seeds
Not all fruit is unsafe, but large pits can cause choking or intestinal obstruction, and some pits or seeds contain compounds that can be harmful when chewed or crushed. Remove pits and seeds before sharing dog-safe fruit.
What to do after a possible poisoning
Call your veterinarian, an emergency veterinary hospital, or an animal poison-control service as soon as possible. If you can, have the product packaging, ingredient list, your dog’s approximate weight, the amount eaten, and the time of exposure available.
Do not induce vomiting or give a home remedy unless a veterinary professional specifically tells you to do so.
