9 Foods Dogs Can’t Eat

9 Foods Dogs Can’t Eat

by Scritch

It’s pretty obvious that dogs should never eat non-food items, but when it comes to foods humans regularly consume, there are many that are dangerous for dogs to eat. For some dogs, anything outside of their regular dog food can upset their tummy, but others are adventurous snackers that can safely enjoy pet-safe people foods like carrots and cucumbers. A variety of foods meant for humans can give your dog a tummy ache or other troubles, but the following nine foods pose a very serious threat of being highly toxic or dangerous to your dog. 

Grapes and raisins

Pet parents who enjoy sharing fruit with their dogs may be surprised to learn that grapes and raisins are highly toxic to dogs. This is one fruit you should absolutely not share with your dog because even small amounts can cause kidney failure. Seek immediate veterinary care if your dog ate any grapes or raisins, and look for symptoms like vomiting, diarrhea, and lethargy.

Macadamia nuts

Do not allow your dog to eat macadamia nuts or any foods that contain them. Ingesting even small amounts can cause vomiting, dizziness, tremors, and weakness. Call your vet as soon as possible for treatment of macadamia nut poisoning.


Fortunately, it’s becoming common knowledge that chocolate is bad for dogs, so most pet parents know to keep the chocolates well out of reach. However, some dogs still manage to seek out the tasty indulgence. After eating chocolate, a dog can experience vomiting and diarrhea, or more serious symptoms such a rapid breathing, seizures, and heart attack. 

Onions, chives, garlic

These vegetables contain disulfides which cause damage to a dog’s red blood cells and ultimately leads to anemia. All forms (raw, cooked, powdered, or in spices) are toxic to dogs, as well as other foods that have been cooked with these vegetables/spices. Contact your veterinarian if your dog has eaten any onions, chives, or garlic.


Commonly found in chewing gum, candy, toothpaste and other foods, xylitol is a sugar-free sweetener that is highly toxic to dogs. After consuming even small amounts of this sugar alcohol, a dog can face a life-threatening drop in blood sugar levels that can lead to liver failure. Seek immediate veterinary care if your dog eats your gum or anything with xylitol in it.


Though most dogs find alcohol distasteful, it’s important to keep all alcohol well out of reach, especially those fruity cocktails if you have a dog that enjoys fruit. Because dogs are generally smaller than people, alcohol affects them much worse. Licking up a few splashed drops likely won’t cause much harm, but if your dog displays loss of coordination and worrisome signs, contact your veterinarian. 

Yeast dough

Yeast and any uncooked doughs made with yeast are dangerous for dogs when consumed. Just as it does to bread, yeast will produce gases and expand inside your dog’s tummy, which can range from mildly uncomfortable to a serious medical concern. Additionally, yeast ferments and produces alcohol which we already know is not good for your pup. 

Cooked bones

You might enjoy sharing meat scraps with your dog, but cooked bones are an absolute no-no. Bones can be sharp, especially after your dog chews them into pieces, which can puncture or injure internal organs. Larger pieces of bones can also cause choking or a blockage in the digestive system. If your dog gets hold of a bone, try to quickly scoop it out of his mouth if it’s safe to do so. Otherwise, contact your veterinarian. 


Coffee, tea, energy drinks, and supplements that contain caffeine should be carefully kept away from dogs. Consuming caffeine can be very dangerous to a dog, starting with increased heart rate and restlessness to more serious symptoms like raised blood pressure and seizures. Seek veterinary care if your dog has consumed caffeine. 

More foods to know

In addition to the hazardous foods mentioned above, there are several other food items that dogs should not eat, including: uncooked white potatoes, fruit seeds and pits (like those from peaches, apricots, cherries, etc.), corn cobs, spicy peppers, fat trimmings or fatty snacks, excess salt, sugar, and most dairy products. 

When in doubt, stick to food and treats made specifically for dogs, or fruits and veggies that are safe for dogs. The rule of thumb is that treats, snacks, and anything outside of your dog’s regular meals should make up no more than 10% of your dog’s diet.
