What Not To Feed A Dog – Top 24 Foods


As dog owners, we should know what not to feed a dog by heart. Feeding them food that is inappropriate for their species out of good intention or ignorance can cause them to suffer, or worse. 

Please keep your dog away from the foods in this list.

1. Chocolates

Chocolate can cause theobromine poisoning; also known as Chocolate poisoning. This is caused by an overdose reaction to Xanthine Alkaloid Theobromine found in tea and cola. Apart from Theobromine, caffeine, fat and added sugar in chocolates are also harmful. This can affect your pet’s central nervous system, heart, kidneys, and gut. Do not feed them even in small amounts.

2. Onions and Garlic

Onions and Garlic contain a toxic principle known as N-propyl disulfide. This compound causes a breakdown of red blood cells, leading to anemia in dogs. This includes leeks, shallots, chives and all onion varieties. 2.5 grams per 1 kilogram of body weight can produce serious results. Call your vet if you suspect your dog ate onions or garlic even in little amounts

8. Ice Cream

In as much as we want to give ice cream to our beloved dogs to show our love, it’s best not to. Ice cream contains a lot of sugar that can contribute to weight gain and diabetes. Not to mention Chocolate which are toxic to dogs. Dairy is another troublesome ingredient. It may also contain Xylitol

9. Raw Fish And Meat

These items are highly debatable. Some dog owners feed their dogs mainly a raw diet but raw food may contain harmful parasites. Be absolutely sure to remove fish bones.

10. Sugar


Sugar can cause dental problems in humans as well as dogs not to mention diabetes and excess weight. It may also feed cancer cells. Xylitol can be fatal to dogs. Make sure to read the label.

11. Cooked Bone

Do not give cooked bones as they are likely to break. A dog given a cooked bone may suffer from broken teeth, blockage and/or cuts to the esophagus/windpipe, punctures in the intestines, rectal bleeding and even death. Raw bones are safer but still come with risks such as broken teeth and choking. Give them bones that are big enough not to be swallowed whole. Or better yet, just don’t risk it. Remember, $10,000 vet bills are not uncommon

12. Alcohol

Fortunately, dogs rarely ingest alcohol because they don’t find the taste appealing. In mild cases, dogs just get disoriented and ‘sleep it off’. In severe cases, you may see muscle tremors, paralysis, shallow breathing, loss of consciousness. If you see any of the following, take your pet to the vet immediately. In social gatherings, keep alcohol and other prohibited foods out of reach.

14. Dairy

Few dogs can tolerate dairy. Most are lactose intolerant. Signs of intolerance are flatulence, vomiting, diarrhea, lethargy, decreased appetite, skin itchiness and a rumbling stomach. If you really must give your pet dairy, make it goat’s milk. Goat’s milk significantly contain less lactose, more calcium and are better tolerated compared to cow’s milk.

The occasional salty treat is fine except when your pet has heart disease in which salt is absolutely forbidden. Large amounts of salt can cause tremors, seizures, high body temperature, and even death. In the winter, wipe their paws to prevent them from licking road salt

things that are toxic to dogs

19. Spinach and Kale

Spinach and Kale can be given to a dog, however, it is not the healthiest choice. The reason being, it contains Oxalic acid which blocks the body’s ability to absorb Calcium and may lead to kidney damage. Though it may take a large amount to reach that point, it is best to choose other vegetables. 

20. Unripe Tomatoes

Solanine is a substance found in the stem and leaves of tomatoes that is harmful to dogs. Dogs that inadvertently eat them suffer from seizures, tremors, muscle weakness, loss of coordination and gastrointestinal upset. Ripe tomatoes can be given in as an occational snack. Unripe tomatoes should be avoided completely. If you’re planning on planting tomatoes in your backyard, choose an area that is inaccessible to your pet. Consider buying an Upside Down tomato planter that you can hang on a fence or post.

21. Raw Potatoes

Raw potatoes contain Solanine just like raw tomatoes. They must be cooked prior to feeding and must be given plain. Skip the salt and butter.

23. Raw Dough

Not that you would feed your dog raw dough but rather a heads-up to be careful whenever you’re baking. Raw dough expands in the warm environment of the stomach and puts pressure on surrounding organs and may make it difficult to breathe and may actually rupture the stomach lining. If you suspect your dog ingested raw dough, take it to the vet right away. What’s more, the yeast in the dough produces alcohol which is highly toxic to dogs. 

Common things that are toxic to dogs

24. CBD Brownies

Brownies spiked with Cannabis can be particularly harmful because of the potentially high THC content plus all the dairy, chocolate and sugar which are all toxic for dogs. Keep them well out of reach.

  1. Wow, totally didn’t see this one coming. I thought I’ll just find some plain list of what to not feed. But I was massively and pleasantly surprised. The comprehensiveness of this is truly remarkable.

    And I’m glad I came across it. I would have been guilty of some of them like cooked bones or cured meat, for sure. That aspect of making sure it doesn’t eat raw dough was also something I wouldn’t have known. Other than that, I had no idea that macadamia nuts are poisonous to dogs.

    Thank you! <3

  2. Great list. I had a 100lb dog when I was younger and I knew not to feed him chocolates and dairy. But he did love a big rib bone when I went out to eat. I always watched him chew away at it. My dog didn’t eat many fruits or vegetables, but he did love peeled grapes. I was eating peeled grapes one night and he took an interest in them. So I gave him one and he loved them. So whenever I brought out some grapes he would always sit next to me and we shared them. He was a great friend to me and he lived to be 15 years old, which is a long life for any dog. He waited until I finished college and we spent his final years together. Thanks for the list. I will bookmark this page if i ever get another dog.

  3. This is a long list of stuff you have listed and if the truth could be told we must do all that we can in keeping our pets from eating these foods. Not because some of them may be good for us that means it may be good for them. I believe this is the reason why so many dogs fall sick and have poor health. Let’s give our dogs what they need to promote good health because the healthier they are the longer they will be around. Thanks so much for sharing a well-deatiled post that is informative with tons of helpful information on caring for our dogs

    I had no clue that dogs could get theobromine poisoning from chocolate, and I never thought about most dogs being lactose intolerant., although it makes sense how this can happen, I just never thought about it.

    I was really surprised to learn that Macadamia nuts are highly poisonous to dogs.

    This article has really opened my understanding to all of the precautions that must be taken in order to keep dogs protected.

    Thank you very much for allowing me the opportunity to comment on your informational article. 

    Blessings To You My Friend,
