Which Foods Suitable For Humans Are Bad For Dogs?

Is your dog eating the wrong food? Off to the vet!

If your dog has eaten something wrong, go to the vet immediately. The vet will ask about the type of food, the amount, and the time your dog ingested it. The vet will then give appropriate treatment based on this.

Unfortunately, treatment is not always possible or it is sometimes too late for this. Therefore, avoid at all costs that your dog ingests the wrong food.

Develop fortitude against your dog’s gaze

Stay strong when your dog looks at you pleadingly. While it can be difficult, you need to develop resistance to his heartwarming canine look. Because what people like to eat is not a standard for dogs.

This also applies to some foods that the dog likes to eat. That’s because certain dogs are very greedy. They cannot distinguish between good food and food that can be harmful or, in the worst case, life-threatening to them.

Foods that dogs should not eat

The following list contains foods that dogs should not eat under any circumstances. However, this list does not pretend to be exhaustive. So there may be other foods that are harmful to your furry friend.

Not sure if your dog has eaten something poisonous? Or is he showing suspicious symptoms? Then go to the vet or a veterinary clinic.

The most common poisoning symptoms are diarrhea  and vomiting. In addition, some toxic foods have other potential effects or can even be fatal, depending on the amount.

Onion and garlic

Onion, garlic, and other bulbous plants are strictly forbidden for dogs. The substances N-propyl disulfide and allicin they contain lead to the destruction of red blood cells in dogs.

Even a very small amount of garlic or onion, namely five grams per kilogram of body weight, can have a very toxic effect, whether fresh, fried, cooked, or dried. One medium-sized onion or one bulb of garlic will poison a 20-pound dog.

Red grapes and (sultanine) raisins

Red grapes and raisins are deadly to some dogs. It is not yet clear why and which dog suffers from the poisoning symptoms. In principle, poisoning symptoms can already occur with an intake of ten grams of grapes per kilogram of body weight or less than three grams of raisins per kilogram.

The main symptoms are vomiting, lethargy, and abdominal cramps after just a few hours. Renal failure and death can occur within 24 to 72 hours.


Nuts, especially walnuts and macadamia nuts, should not be eaten by dogs. These two types, in particular, can lead to nerve and muscle damage. For example, four macadamia nuts would already cause this damage in a dog of 30 kilos.

Other types of nuts, depending on their size, can lead to intestinal obstruction if ingested.

Other foods that dogs should not eat

Raw pork

You should never feed your dog raw pork, ham or salami. Pigs can have Aujeszky’s disease undetected. An infection with this virus is always fatal for dogs.


Poultry bones and cooked bones have no place in a dog’s food bowl. Cooking causes the bones to become porous and shatter easily when chewed. These splinters can cause enormous damage to the stomach or intestinal wall and even lead to bleeding.

Coffee Tea

Coffee, tea, and other foods containing caffeine (cola, energy drinks) can have fatal effects on our dogs’ nervous systems. The compound in it, caffeine (or theine), causes palpitations, vomiting, and restlessness within hours.

In the further course, the symptoms will be the same as with chocolate poisoning or with kidney problems and nerve damage. The minimum lethal dose is about seven coffee beans per kilogram of body weight.

Sweeteners, birch sugar & xylitol

Sweeteners, birch sugar, and xylitol cause low blood sugar in dogs between 30 and 60 minutes. Left untreated, it can lead to convulsions, coma, and even the death of dogs.

Depending on the dose, acute liver failure may also occur. Depending on the xylitol content, one to three gums can be fatal for a ten-pound dog.

Chocolate & cocoa

Chocolate and cocoa contain the dog toxic substance theobromine. The darker the chocolate, the higher the theobromine content. The first symptoms appear after a few hours. These include vomiting, restlessness and tremors. After a longer period of time, cramps, breathing difficulties and a rapid heartbeat are added. Eventually, heart failure will occur, which can lead to death.

Always try to determine the amount of chocolate ingested and contact your veterinarian or veterinary clinic immediately. Even 50 grams of dark chocolate can cause poisoning symptoms in a dog of 20 kilos.

Foods that dogs and puppies should only eat in moderation

For many foods, it depends on the amount whether they are harmful or not. However, sometimes it is impossible to predict exactly what amount will be harmful to an individual dog. Therefore, to be on the safe side, you should also avoid these foods.

Added to that, some foods are toxic only in raw form but can be safely fed cooked.

Which vegetables should dogs only eat in moderation?


You have to be careful with nightshade crops such as tomatoes, aubergines, peppers and potatoes. Especially the green parts of these fruits and germinating potatoes contain a lot of solanine.

Potatoes and red or yellow peppers should therefore only be fed cooked. You can give tomatoes raw in small quantities. However, carefully remove the green fruit parts. Symptoms of poisoning include irritation of the mucous membranes, diarrhea, and vomiting.


No one can say for sure how the ingredients of a mushroom specifically affect the organism of dogs. They can damage the organs and be astringent or carcinogenic. That’s why mushrooms don’t belong in a dog’s food bowl.


Cabbage causes a strong bloating in dogs and should therefore only be fed in small quantities.

Beans and legumes

Beans and other legumes should never be fed uncooked. Raw, these fruits contain Phasin, which is harmful to humans and dogs. This leads to vomiting, abdominal cramps, and bloody diarrhea.

What fruits and other foods should dog only eat in moderation?


Avocados contain the substance persine. This substance is found in particularly large quantities in the skin and pit of the fruit. However, some avocados can also have a lot of persin in the flesh. This causes diarrhea and vomiting in dogs. In addition, if your dog swallows the kernel, it can lead to an obstruction in the gut.

Stone fruits/fruit pits
Stone fruits include apricots, plums, cherries and peaches. The prussic acid contained in the kernels is released when bitten and can lead to serious neurological disorders. Kernels swallowed whole can also lead to intestinal obstruction.


Like fruit kernels, almonds contain hydrocyanic acid. This can lead to serious neurological disorders. Almonds swallowed whole can also lead to intestinal obstruction.


Honden hebben een aanzienlijk lagere tolerantiedrempel voor alcohol. In het begin of bij kleine hoeveelheden zijn de symptomen hetzelfde als bij mensen. In een later stadium of na een grotere hoeveelheid krijgt de hond last van braken, abnormale coördinatie, ademnood, coma en overlijden. Bovendien leidt het langdurig toedienen van kleine hoeveelheden alcohol tot enorme leverschade.

Raw eggs

Raw eggs hinder the absorption of biotin. This substance is important for carbohydrate, protein and fat metabolism. In addition, raw eggs can be a risk factor for salmonella poisoning. Therefore, feed them only cooked.

Other foods that dogs should not eat

Foods that are too greasy and highly spicy are not digestible for dogs. Dogs can get diarrhea or vomit from fatty and spicy foods. In addition, eating very fatty foods in the long term can lead to inflammation of the pancreas (pancreatitis).

Fruits usually have very high sugar content. So give your dog a small piece every now and then.

Although salt is in principle not toxic to dogs, the amount is decisive. This can damage the heart and kidneys. So you have to be extra careful with older, weak and sick dogs.

Only feed fish in small amounts and never raw to your dog. The high protein and fat content can cause vomiting or diarrhea in some dogs. Also make sure there are no bones in it.

Milk products cause lactose intolerance in some dogs. This often leads to severe diarrhea. Therefore, dogs should never be fed pure milk and only a little bit of other dairy products (yogurt or cottage cheese).
