Human Foods That Are Toxic to Dogs: The Owner's Safety List

Several common human foods are toxic to dogs and should never be shared — the best-known include chocolate, grapes and raisins, onions and garlic, xylitol, and alcohol. Dogs are famously food-motivated, and part of loving them is knowing which of your everyday foods can quietly put them at risk. This safety list covers the human foods most often flagged by veterinarians as dangerous, why they're a problem, and exactly what to do if your dog gets into something they shouldn't.

Keep this handy — a quick glance can prevent a scary night at the emergency clinic.

The Human Foods to Keep Away From Dogs

Every dog is different, and sensitivity can vary, so the safest approach is to treat all of the following as off-limits.

Chocolate

Grapes and Raisins

Onions, Garlic, and Chives

Xylitol (Birch Sugar)

Alcohol

Caffeine

Macadamia Nuts

Grapes' Company: Other Common Culprits

• Raw yeast dough — can expand and produce alcohol in the stomach.
• Foods very high in salt or fat — can cause illness or contribute to conditions like pancreatitis.
• Certain fruit pits and seeds — best avoided due to choking and other risks.
• Avocado — often cited as a food to be cautious with in dogs; when unsure, skip it.

This isn't an exhaustive list, and new products (and new recipes) appear all the time. When you're not certain about a food, the safe default is simple: don't share it.

Warning Signs to Watch For

Because these foods affect dogs in different ways, symptoms vary widely. In general, signs that something may be wrong include:

• Vomiting or diarrhea
• Unusual tiredness, weakness, or restlessness
• Loss of appetite
• Tremors, unsteadiness, or trouble walking
• Changes in drinking or urinating
• Any behavior that's out of the ordinary for your dog

These signs are not specific to any single food, which is why you should never try to diagnose the problem yourself. When in doubt, call a professional.

What to Do If Your Dog Eats Something Toxic

If you know or suspect your dog ate something on this list, act quickly and calmly:

1. Remove any remaining food so your dog can't eat more.
2. Call your veterinarian right away, and describe what your dog ate and roughly how much.
3. Contact ASPCA Animal Poison Control at (888) 426-4435 if you can't reach your vet immediately — it's a trusted resource for pet parents in exactly these moments.
4. Don't induce vomiting or give home remedies unless a professional specifically instructs you to.
5. Keep the packaging or a photo so your vet knows exactly what was involved.

The faster you reach out, the more your veterinary team can do — so make the call rather than waiting to see what happens.

Build Safer Habits at Home

A little prevention goes a long way:

• Keep counters, tables, and trash cans out of reach or securely covered.
• Store purses and bags (which often hold gum or candy) up high.
• Let houseguests and kids know the "no table scraps" rule.
• Keep this list somewhere handy, like the fridge.

It turns a quick scan into real peace of mind.

The Bottom Line

Knowing which human foods are toxic to dogs is one of the most protective things you can do as a pet parent. Keep chocolate, grapes and raisins, onions and garlic, xylitol, alcohol, caffeine, and macadamia nuts firmly off the menu, watch for anything out of the ordinary, and don't hesitate to call for help when you need it. With a few smart habits and this list close by, you can keep mealtime joyful and your dog safe.

In an emergency, remember: your vet or ASPCA Animal Poison Control at (888) 426-4435.
