Dog Food Without Corn: Nine Foods Your Dog Should Never Eat

Foods Your Dog Should Never Eat

Dogs may be man’s best friend, but that doesn’t mean they should eat the same foods we do. Some foods that are edible for humans may be harmful (and even fatal) for dogs.

Milk and Other Dairy Products

Yes, even dogs can be lactose intolerant. If your dog vomits or has diarrhea after consuming dairy products, it’s best for him to switch to other types of meals, such as dog food without corn.


Nearly every part of the avocado plant contains a toxin called persin, which is known to cause gastrointestinal problems, respiratory distress, and fluid accumulation around the heart. Although the American Society for the Prevention of Cruelty to Animals (ASPCA) says that avocado ingredients in pet foods are generally not hazardous, it’s better to err on the side of caution when it comes to meals for your beloved dog.


Does your dog wag his tail every time he sees you open a Hershey’s bar? Tempting as it is to share with him the heavenly taste of chocolate, keep in mind that this food has caffeine and theobromine. Together, these substances can cause toxicosis (which, in turn, can lead to death) in dogs.

Fruit Seeds and Pits

When you throw away apple seeds, persimmon seeds, plum pits, peach pits, and cherry pits, make sure you don’t let your dog get anywhere near them. Otherwise, your pup will suffer from a host of gastrointestinal problems, such as obstruction, enteritis, and diarrhea. You can use dog food without corn to distract your dog from the garbage bin where you dumped these seeds and pits.


Commercially sold mushrooms appear to have no negative effects on canines. However, the ones that grow in the wild can poison your pooch, so it’s a good idea to regularly clear your yard of these. In case your dog displays signs of mushroom poisoning (e.g. vomiting, diarrhea, nervous system abnormalities, fever), bring him to the veterinarian along with a sample of the offending mushroom.

Onions and Garlic

All members of the onion family—scallions, garlic, shallots, leeks, and (of course) onions—are off-limits to your dog. According to the ASPCA, these foods have compounds that destroy a dog’s red blood cells. In severe cases of toxicosis caused by onions, your veterinarian may recommend blood transfusions

Tree Nuts

Tree nuts include Brazil nuts, pecans, pistachios, and walnuts. Although they only contain low levels of the poison Aflatoxin, your dog’s hypersensitivity to this toxin can be problematic in case of ingestion. Peanut butter treats are fine, but raw peanuts aren’t.


Ever wondered what makes those low-calorie snacks sweet, despite the lack of sugar? It’s xylitol. This sweetener is safe for humans, but it can make your dog’s blood sugar levels drop. Bring your dog to the veterinarian as soon as he swallows products with xylitol.


There are four reasons you should choose dog food without corn. First, corn raises your dog’s sugar levels. Second, it’s one of the identified food allergens that affect dogs. Third, it’s not easily digestible in its whole grain form. Fourth, it has little, if any, nutritional value to your dog.
