10 forbidden foods for dogs that you should avoid


If you live with a dog or you are responsible for its health and care, it is essential that you know the list of forbidden foods for dogs. If, due to ignorance, you share with your pet any of these forbidden foods for dogs, it is possible that it will suffer intoxication and a series of damages in its organism that can be fatal.

Therefore, to avoid endangering your dog, in Las Almenas we have prepared a list of 10 forbidden foods for dogs that under no circumstances should you offer to your furry friend. In case of an accident, we also show you how to act.


What are the forbidden foods for dogs?

Whether you feed your pet with dog food or homemade food, it is necessary to avoid giving him any of the forbidden foods for dogs that are listed here.


1.Chocolate, coffee and tea

In our Las Almenas blog we have already talked about the dangers of chocolate ( due to the theobromine contained in cocoa. Theobromine is a natural substance in cocoa and tea that stimulates the central nervous system. Similar in structure to theobromine is the caffeine in coffee. Both have a stimulant effect that, even in very small doses can cause cardiac arrhythmias, convulsions and even death of the animal.

So you know that no matter how appetizing chocolate is, you should never offer it to your furry friend. But in case he has accidentally ingested it, the best thing to do is to induce vomiting as soon as possible and go to the veterinary emergency room.




2-Onion and garlic

Onion is one of the most well-known forbidden foods for dogs. Its allicin content, which is released after chewing, and the substance in which it is degraded, cause an oxidative lesion.

The seriousness of this injury is that the rupture of the cell membranes causes hemolytic anemia, that is, a liver disease for which blood transfusion may be necessary and, as a last resort, surgery of the spleen to remove it, if it has become inflamed.

Accidental and minimal consumption of onion should not be a concern, but if onion is given continuously you may see your dog show gastrointestinal problems (vomiting, weakness) and even jaundice on the skin.

As with onions, garlic also contains allicin and therefore can cause hemolytic anemia with regular consumption, so both foods should be avoided.



In our list of forbidden foods for dogs, avocado cannot be missing. In this case, it is due to its persin content, a toxin derived from avocado fatty acids, especially present in the stone and leaves, and not so much in the flesh. However, it is advisable not to gamble and prevent dogs from consuming any part of the avocado.

Avocado is not the only fruit that can be harmful to dogs. If you want to offer your dog any fruit or vegetable, we recommend you to read our list of healthy fruits and vegetables for your dog. This way, you will get out of any doubt.


4-Cooked bones

Now that we have talked about avocado bones, let’s talk about bones in general. It is curious to think that the bones that we like so much are one of the forbidden foods for dogs. But the reality is that, if they are cooked, you should avoid at all costs that he puts them in his mouth.

If you want to give your dog a treat and offer him a bone, it must be raw. Cooked bones break in a different way because they have lost their elasticity in the cooking process and may have splinters that can pose a risk to our dog by causing an obstruction of the trachea, injuries and perforations, tearing and many other internal injuries. Therefore, it is convenient that the bone is raw and that it has meat around it, that it is meaty.



Sometimes, when we strive to give our furry friends a balanced diet, we sometimes give them foods that should not be given. This is the case with cherries.

In addition to the risk posed by its pits, cherry is another forbidden food for dogs, as it contains cyanide, specifically amygdalin, a cyanide-producing chemical found in the seeds of many foods, such as apples or almonds.



If certain mushrooms are already toxic for humans, imagine for animals! Undoubtedly, mushrooms are one of the forbidden foods for dogs, especially those belonging to the genera Amanita, Lepiota and Galerina, which are potentially fatal for them.

In case of mushroom poisoning, dogs show vomiting, drooling, diarrhea, tremors, confusion, convulsions and, in the most severe cases, multi-organ failure that can lead to death.

Therefore, if your dog has eaten a mushroom or fungus of which you do not know its toxicity, the best thing to do is to go to the veterinarian as soon as possible. Keep in mind that some mushrooms act very fast, in less than 30 minutes.



Cakes, bread and pastries are so tasty that you may be tempted to share them with your furry friend, but this would be a big mistake, as they contain yeast.

The reason why yeast is on our list of forbidden foods for dogs is because it can spread from the stomach to the intestines causing gas and respiratory problems.

Keep in mind that yeast is formed by common microorganisms that are harmless to the skin flora of dogs, but in some dogs, yeast proliferates in an exaggerated way affecting the skin of various areas of the body (pads, groin, armpits, around the anus or vulva) and even the ear.



Sugar is considered to be another forbidden food for dogs because it can cause obesity and in some cases diabetes, even generating long-term cardiovascular complications, as well as the famous loss of vision.

Dogs should not eat treats or cakes or similar foods, such as jams and quinces, on a regular basis. Nothing will happen to your dog because he licks your birthday cake, but do not overdo it and use common sense.



We have the habit of using salt as a condiment even when preparing homemade recipes for our dogs. However, a high consumption of sodium chloride can lead to dehydration, as well as cardiac and renal pathologies. Moreover, salt intoxication may occur, which, in addition to vomiting or diarrhea, brings with it polydipsia (strong urge to drink) and polyuria (strong urge to urinate).

However, dogs can tolerate a certain amount of salt, in fact, dog food contains it, but excessive consumption must be avoided and this is not always easy, as salt is not evident in many foods. So beware of excessive amounts or if he accidentally ingests some products containing high doses of salt.



The last of the forbidden foods for dogs that we want to detail you is milk. Specifically, it is lactose, which is the sugar in milk that dogs cannot digest. However, they can eat cheese or yogurt, where the lactose has been fermented. Therefore, dairy products are a good supplement of calcium and protein.

Milk is not a deadly food, but it does cause a lot of discomfort and diarrhea in dogs, which could dehydrate them, so it is advisable to avoid ingesting it.


What to do if my dog eats forbidden foods?

If you notice that your dog is panting, muscle spasms, vomiting or suffering from diarrhea, it is necessary to go to the vet as soon as possible.

When you go to the vet, remember to have as much information as you can about any forbidden dog food he may have consumed. The more information you can provide, the better. You will also need to give the veterinarian all the details regarding any symptoms you may have observed in the dog.

There is a possibility, if you are far away from the vet and it is a very toxic food (mushrooms, chocolate), that you may have to make your dog vomit to prevent the food from being digested by the body and causing any harm.

Your veterinarian may tell you how to make your dog vomit without causing any harm to your furry friend. In any case, you will have to do it as soon as possible and never more than 2 hours after ingestion because it will have already been digested.

As you can see, there are a lot of forbidden foods for dogs. Some of them can be a veterinary emergency situation, so you should know them and avoid them at all costs.


All the information that we have provided you from our blog of Las Almenas is totally rigorous, however, if you have any doubt or symptom, you should contact your veterinarian.
