Blog Dangerous Foods for Dogs: What to Keep Off Their Plate

Dogs have a talent for finding food they were never supposed to eat. Drop something on the kitchen floor and your dog will probably appear out of nowhere. Leave a plate unattended for 30 seconds and suddenly you are wondering whether the dog has learned to climb.

Some human foods are harmless in small amounts. Others can make a dog seriously sick. The list has also changed a bit from older pet-safety advice, so here are the foods worth keeping away from your pup in 2026.

Chocolate, coffee and caffeine

Chocolate is one of the big ones. Chocolate, coffee and other sources of caffeine contain methylxanthines, which can cause vomiting, diarrhea, panting, excessive thirst and urination, abnormal heart rhythms, tremors, seizures and, in severe cases, death.

The darker the chocolate, the higher the concentration of these compounds. Baking chocolate and cocoa powder are especially concerning. Keep chocolate, coffee and caffeinated products away from your dog, including during baking and holiday celebrations.

Grapes and raisins

Grapes and raisins can cause kidney damage in dogs. The ASPCA recommends keeping them out of your dog’s reach rather than trying to figure out how much might be safe.

That includes foods containing raisins. Check ingredient labels before sharing baked goods with your pup.

Onions, garlic and chives

Onions, garlic and chives are members of the Allium family and can cause gastrointestinal irritation and damage to red blood cells in dogs. They can turn up in foods you would not expect, including sauces, soups, seasoned meats and leftovers.

Plain cooked meat may be a better choice when you want to share a little dinner with your dog. Skip the seasoning.

Xylitol

Xylitol is a sugar substitute found in some sugar-free gum, candy, baked goods, toothpaste and other products. It can cause a rapid drop in blood sugar and may lead to liver damage in dogs.

Read labels before giving your dog anything made for people. “Sugar-free” does not mean dog-friendly.

Alcohol and raw yeast dough

Alcohol should never be given to dogs. Raw yeast dough is another problem because it can expand in the digestive tract and produce alcohol as it ferments. The result can include dangerous bloating as well as alcohol toxicity.

So if you are making homemade bread or pizza dough, keep the bowl away from your four-legged kitchen assistant.

Macadamia nuts and very fatty foods

Macadamia nuts can cause weakness, vomiting, tremors and other symptoms in dogs. Other nuts and high-fat foods can also cause stomach upset and, in some cases, pancreatitis.

That leftover piece of greasy bacon may get you the biggest puppy eyes in the world. It still may not be worth it.

What about dairy and avocado?

This is where some older dog-food lists need a little cleanup. Dairy products are not automatically poisonous to dogs, but many dogs have trouble digesting lactose. Milk and other dairy products can cause diarrhea or digestive upset.

Avocado is also more complicated than the old “avocado is poisonous to dogs” warning suggests. The ASPCA notes that avocado is primarily a concern for certain other animals, while the pit can create a gastrointestinal obstruction if swallowed.

That does not mean you should start handing your dog avocado toast. It means the old advice needs some context.

What treats can you give your dog?

The easiest answer is dog treats made specifically for dogs, especially when you are unsure about an ingredient.

Very Important Paws has a specialty boutique with dog food and treats, including products from brands such as SmartBones, Pet Honesty, and Churu. VIP’s dog day camp also includes dog-friendly treats such as VIP cookies and dog-friendly ice cream during scheduled activities.

And if your dog has a habit of turning every snack into a full investigation, keeping people food out of reach is probably the best first step.

If you think your dog has eaten something potentially toxic, do not wait for symptoms before seeking veterinary advice. Note what your dog ate and how much, and contact your veterinarian or an appropriate animal poison-control service. The ASPCA recommends keeping track of the amount ingested when seeking help.

Your dog may look personally offended when you say no to the chocolate chip cookie. Let them be offended. They will probably forgive you when the actual dog treats come out.
