Many owners tend to neglect their dog’s diet a lot and they offer them these foods that according to nutrition experts are not suitable for their health.

There are several foods that are frequently consumed by people, that you keep in your home and that can cause serious problems to your pet. There may be other foods that you should not give your dog, so consult your veterinarian before giving him any other food in addition to his regular food.

In today’s article, we tell you about some of the foods that you should not include in the diet of dogs, regardless of breed, because they significantly alter their metabolism, greatly affecting their health.


We will start by mentioning chocolate! Chocolate has a compound called theobromine, a natural compound of the same chocolate that causes different reactions and present different variations between one animal and another. Dogs with epilepsy are the most affected by this substance.

Theobromine can cause cardiac arrhythmia, especially if the animal is excited, which can lead to a myocardial infarction that can be fatal.

On the other hand, theobromine causes irritation of the gastrointestinal tract and, in some animals, can cause internal bleeding which, in some cases, results in death within a day or so.

Dried Fruits

Avoid giving your dog nuts. Because of their size, they can choke your dog and are high in fat that can cause stomach upset. For example, macadamia nuts have been shown to be highly toxic to dogs. Although they do not usually cause death, they can cause your dog to become unable to walk, vomit, become lethargic and tremble.

Many varieties of nuts are harmful because of their high phosphorus content, which can cause gallstones.

Garlic and Onion

Onions and garlic are used to flavor our meals, but for dogs, these common ingredients are toxic. Whether cooked or raw, eating onions and garlic can damage your dog’s red blood cells, which can lead to anemia.

Onions, especially raw, have been shown to cause hemolytic anemia in dogs.


Poisoning from eating potatoes has been reported in both humans and dogs. The alkaloids are found in the green shoots and skin, which are produced by exposure of the tubers to sunlight during development or after harvest.

The likelihood of poisoning is relatively low because solanine is poorly absorbed and hydrolyzed, forming a less toxic compound whose metabolites are rapidly eliminated. Boiled potatoes and mashed potatoes are tasty and also very nutritious and digestible for your dog.


It’s not the pulp of the avocado, but the seed, skin and leaves that can harm your dog. The leaves contain a substance called persin, which causes vomiting and diarrhea.

There is some controversy as to whether the avocado pulp is harmful, but in any case, the bone and leaves are, so it is best to avoid them.

Chicken Bones

Hard bones that don’t break are good for strengthening our dog’s teeth and jaw, but some, like chicken bones, are very dangerous because they can break and stay in the mouth and throat.

It is best to consult our veterinarian before giving bones to our dog, and have him advise you.

Raw Fish

Sushi for your dog is a forbidden food because the thiamine it contains can be fatal for him.

If you want to give another fish to your sushi, you must remove the bones well, and it is very important to cook it before giving it to the dogs, firstly, because raw fish can contain bacteria and parasites.

And secondly, because well-cooked fish is much easier to digest for our dogs.

There you go! You now know the foods that you should not be giving to your dog to preserve it’s health. Do you have any other advice that you can share with us about dogs’ diet? Leave a comment below!
