Can Dogs Eat That? 25 Common Human Foods Answered by a Vet

Every dog owner has been there — your dog is staring at you with those eyes while you eat, and you wonder: can they have some? We analyzed search data from thousands of pet owners to find the 25 foods people ask about most, then got definitive answers from veterinarians.

Each food is rated as Safe, Caution, or Toxic — so you know at a glance whether to share or skip.

Baked Goods & Sweets

1. Biscoff Cookies — CAUTION

Not toxic, but not recommended. High in sugar, fat, and spices. The real risk is Biscoff cookie butter/spread, which is even higher in fat and can trigger pancreatitis. One cookie won't kill your dog, but don't make it a habit.

2. Croissants — CAUTION

Plain croissants are not toxic but are very high in butter/fat. The danger is what's inside — chocolate croissants are toxic, and almond or raisin varieties can be dangerous. Plain, small piece = probably fine. Whole chocolate croissant = call your vet.

3. Quiche — CAUTION

Depends on ingredients. Plain egg and cheese quiche in small amounts is generally okay. But quiche with onions, garlic, leeks, or heavy cream is problematic. Quiche Lorraine typically contains enough onion to be a concern for small dogs.

4. Ice Cream — CAUTION

Most dogs are lactose intolerant to some degree. Plain vanilla in small amounts usually causes only mild GI upset. Never give chocolate ice cream (theobromine toxicity) or any ice cream with xylitol, raisins, macadamia nuts, or coffee flavoring.

Condiments & Spreads

5. Mayonnaise — CAUTION

Not toxic, but very high in fat. Small lick = fine. Large amount = risk of pancreatitis, especially in small dogs. Avoid flavored mayo with garlic or onion.

6. Honey — SAFE (with caveats)

Safe for healthy adult dogs in small amounts. High in sugar, so not ideal for diabetic or overweight dogs. Never give honey to puppies under 1 year due to botulism risk.

7. Sunflower Oil — SAFE (in moderation)

Non-toxic and can actually benefit your dog's coat. Small amounts are fine. Large amounts can cause diarrhea and weight gain due to high calorie content.

8. Stevia — SAFE for dogs, CAUTION for cats

Stevia itself is not toxic to dogs or cats. However, products containing stevia often also contain xylitol — always check the full ingredient list. Pure stevia extract is generally considered safe.

Snacks & Junk Food

9. Cheese Puffs / Cheese Curls — CAUTION

Not toxic, but high in sodium, fat, and artificial ingredients. Check the seasoning for onion or garlic powder — these are toxic to dogs. A few puffs won't cause an emergency, but they're not a healthy treat.

10. Popcorn — SAFE (plain)

Plain, air-popped popcorn is safe. Buttered, salted, or flavored popcorn is not recommended. Unpopped kernels are a choking hazard and can damage teeth.

Fruits & Vegetables

11. Bananas — SAFE

Safe and nutritious in moderation. High in potassium, vitamins, and fiber. High in sugar, so keep portions small — a few slices for a medium dog.

12. Apples — SAFE (no seeds)

Apple flesh is safe and healthy. Remove seeds and core — apple seeds contain amygdalin, which converts to cyanide. A few seeds won't cause harm, but it's best practice to remove them.

13. Grapes/Raisins — TOXIC

Never feed grapes or raisins to dogs. Even a single grape can cause acute kidney failure. The toxic substance is still unknown, and there's no safe dose. This includes grape juice, wine, and currants.

14. Watermelon — SAFE (seedless)

Safe and hydrating. Remove seeds (can cause intestinal blockage) and rind (difficult to digest). The flesh is a great summer treat.

15. Yuca/Cassava — CAUTION

Cooked yuca is generally safe in small amounts. Raw yuca is dangerous — it contains cyanogenic glycosides that release cyanide. Always serve fully cooked and peeled.

Proteins & Dairy

16. Eggs — SAFE (cooked)

Cooked eggs are an excellent protein source. Scrambled or hard-boiled without seasoning are best. Raw eggs carry a small risk of Salmonella and contain avidin, which interferes with biotin absorption.

17. Aloe Vera — TOXIC

The latex layer of aloe vera contains saponins and anthraquinones that cause vomiting, diarrhea, and tremors. While the inner gel is less toxic, it's best to keep aloe away from pets entirely.

Common Kitchen Ingredients

18. Garlic — TOXIC

Garlic is toxic to dogs and cats. It damages red blood cells and causes hemolytic anemia. Garlic is about 5x more toxic than onions. Symptoms may not appear for several days. Garlic powder is even more concentrated and dangerous.

19. Onions — TOXIC

All forms of onion (raw, cooked, powder, dehydrated) are toxic. Like garlic, onions destroy red blood cells. This includes shallots, leeks, and chives. Even small amounts in cooked food can be harmful over time.

20. Lavender — CAUTION

The plant itself causes mild GI upset if eaten. Lavender essential oil is more dangerous — it can cause nausea, vomiting, and liver damage, especially in cats. Keep essential oils and diffusers away from pets.

Other Common Questions

21. Roses — SAFE

Rose petals are non-toxic. The thorns are the real hazard — they can injure mouths, paws, and GI tract if swallowed. Remove thorns from any roses in reach of your dog.

22. Spider Plants — SAFE

Spider plants are non-toxic to dogs (and cats). If your dog eats one, they might have mild GI upset from the plant fiber, but there's no toxicity concern. Cats are often attracted to spider plants, which is fine.

23. Marigolds — SAFE (with caution)

Common garden marigolds (Tagetes) can cause mild GI irritation and skin irritation if eaten in large amounts, but they're not truly toxic. They're generally considered safe for dogs.

24. Hibiscus — CAUTION

Rose of Sharon hibiscus can cause vomiting, diarrhea, and nausea in dogs. Tropical hibiscus is generally less problematic. If your dog ate a significant amount of hibiscus flowers, contact your vet.

25. Crescent Rolls — CAUTION

Raw dough is the real danger. Unbaked yeast dough expands in a dog's stomach, causing bloat, and the fermentation process produces alcohol. Baked crescent rolls are similar to croissants — high fat but not toxic in small amounts.

The Bottom Line

When in doubt, don't share. Most human foods that are "safe" for dogs are still not ideal — they're high in sugar, fat, or salt that dogs don't need. The safest treats are those made specifically for dogs, or plain fruits and vegetables like carrots, blueberries, and apple slices.
