What Can Dogs Not Eat : PetKindly


Sometimes the list of things dogs are not allowed to eat seems longer than the permitted feed. Many foods that we humans enjoy regularly pose a danger to our four-legged friends. Most of them contain individual active ingredients that are toxic to the dog and can seriously damage the organism. Some foods can even lead to death.

What is particularly toxic to dogs?

A few substances lead to death even in very small quantities and are therefore particularly toxic to dogs:

  • Raisins and grapes
  • Caffeinated drinks
  • Cocoa and chocolate
  • Almonds and fruit seeds
  • salt
  • raw pork
  • Sweetener xylitol or birch sugar

What dogs are not allowed to eat as a list

Here we have created a list of all foods that dogs cannot tolerate. Under each heading you will find a brief explanation of the substances contained and why dogs can also harm harmless foods.

Please make sure that your dog never gets these things to eat. Also think about the danger during a walk. Should your dog nevertheless eat something prohibited, do not hesitate to see a veterinarian as soon as possible. You can download the list in business card format and print it out yourself. Simply enter your email address and click on “I want to get it for free”.

Immediately afterwards we will send you the list that you can print out. Some readers have already sealed them in and are always with them.

Alcohol must be absolutely taboo for dogs. Because this is pure poison. This should also apply to malt beer , which has a low alcohol content.

Depending on the amount consumed and the alcohol content, it leads to vomiting and coordination problems. Alcohol poisoning can occur, which can lead to shortness of breath, coma and ultimately death. Alcohol has a negative effect on liver function.

Eggplant, raw

Aubergines are a nightshade family. These contain the poison solanine. Eggplants should never be fed raw.


There are different types of avocados. Some of them contain the poisonous active ingredient persine. This substance can lead to heart muscle damage and even death. Even if it is a non-toxic variety, the avocado is very high in fat and leads to severe diarrhea.

Since the individual varieties are very difficult to distinguish for laypeople, generally no avocados should end up in the dog bowl .

Wild garlic and chives

Wild garlic and chives are all types of leek and contain allium. This causes a change in the red blood cells, which can ultimately lead to anemia and death.

Raw eggs

Raw egg white inhibits the absorption of biotin. However, the dog needs biotin for a regulated carbohydrate, protein and fat metabolism. You can occasionally feed raw egg yolks. However, keep an eye on the risk of salmonella. You can feed hard-boiled eggs now and then without worry. Here you will find the detailed article on whether dogs are allowed to eat eggs .

Caffeinated drinks such as coffee, cola and energy drinks

Caffeine increases blood pressure and speeds up the pulse. It also narrows the blood vessels. A dog’s metabolism is not designed to process caffeine. Restlessness, tremors , vomiting, diarrhea and seizures can occur. Cardiac arrhythmias can be life-threatening.

Poultry bones

Poultry bones are of course not poisonous. However, they splinter and can cause serious injuries in the dog’s digestive tract.


There’s nothing to say about a few oatmeal here or there. However, grain is used as a filling material in many industrially produced dog foods. That was also the crucial point to start this website .

Therefore, pay attention to food without grain and better feed varieties with millet, corn and rice .


Cocoa contains theobromine, which is toxic to dogs. Theobromine can cause nausea, vomiting, fever and cramps.Even small amounts of theobromine can be fatal to sensitive and especially small dogs. Cardiovascular failure and death occur when larger amounts are ingested.

Theobromine is broken down very slowly by the dog’s body. Consistent cocoa consumption can therefore also be dangerous in small quantities. Here you can find a detailed article about cocoa and theobromine .

Raw potatoes

Potatoes belong to the nightshade family and, like eggplants and peppers , contain the poisonous solanine. Solanine is neutralized by cooking. Boiled potatoes are an optimal source of carbohydrates for the dog and are mainly popular in the hypoallergenic diet.

The green parts of potatoes contain particularly high concentrations of solanine.


Garlic is often recommended as a natural remedy for parasites. We debunk this myth in the article “ Is Garlic Toxic for Dogs? ”

Dogs probably tolerate it in very small quantities. In larger quantities, however, the allium contained changes the red blood cells. This leads to anemia and can lead to death. Therefore, feed garlic with great caution.

Macadamia nuts

Why the macadamia nut is poisonous to dogs is not really known. If the dog eats these nuts, general weakness, vomiting, fever, gait disorders and even lameness can occur.


In the botanical sense, almonds are not stone nuts, but stone fruits. Bitter almonds can also be found among the sweet almonds. They contain the substance amygdalin. The toxic hydrocyanic acid is split off during the digestive process. If the dog eats these bitter almonds, this can be very dangerous, especially for a small dog.


Lactose, i.e. milk sugar, is generally only digestible for puppies . After that, dogs should no longer drink milk.

However, dairy products such as yoghurt , curd cheese and cottage cheese are often fed as light food.

Fruit kernels

Like bitter almonds, plum fruit kernels also contain apricot or cherry hydrocyanic acid.

The hydrocyanic acid can lead to severe poisoning. Symptoms include shortness of breath, vomiting, fever, diarrhea, drooling and cramps. Make sure to remove the fruit seeds before feeding these types of fruit .

Tomatoes, raw

Like aubergines and potatoes, tomatoes are a nightshade family. They can be fed in small quantities . Be sure to remove all green areas because they contain toxic solanine. When cooked, tomatoes are completely harmless.

Raisins and grapes

Raisins and grapes can even lead to short-term death in dogs . At the beginning the dog vomits and no longer eats . Abdominal pain and diarrhea follow. Renal failure and hypercalcaemia can occur as early as 24 hours after the fruit has been ingested.

The amounts that can lead to the death of the animals have not yet been exactly established. It is estimated that around 11.6 grams of grapes per kilogram of dog body weight. Raisins are expected to weigh around 3 grams per kilogram of body weight.


A little pinch of salt will not harm the dog. Larger amounts are dangerous from just 0.5 grams of table salt per kilogram of body weight and can lead to death in dogs.

Salt increases the amount of fluid in the body. The dog has to drink more water. If the dog has heart problems, the fluid cannot be excreted because of the reduced cardiac output. Too much salt leads to high blood pressure and kidney damage. The amount of salt can hardly be checked with nibbles. Therefore, salty pastries should be taboo for dogs.


Chocolate contains cocoa, which in turn contains theobromine. The proportion of theobromine varies depending on the type of chocolate. Most theobromine contains dark chocolate. In sensitive dogs, a small amount of 90 milligrams per kilogram of body weight can be fatal.

Chocolate is particularly dangerous for small dog breeds, puppies and young dogs . Symptoms include restlessness, nausea, cramps and fever. Regular feeding in small quantities is also dangerous because theobromine is broken down very slowly in the dog’s body.

Raw pork

Raw pork can contain the Aujeszky virus. This virus is harmless to humans. However, it causes symptoms in dogs that are similar to rabies. If the disease breaks out, there is no cure. It ends with death.

Why not feed raw pork?

The virus is killed during cooking. You can also feed dried pig ears or noses without hesitation. Pork still plays a minor role in dog nutrition and is hardly processed in finished feed.


Green and black tea contains tea. This active ingredient corresponds to caffeine. Therefore dogs should avoid teas like green and black tea. Herbal teas are of course allowed and offer themselves as natural remedies .


Xylitol is a sugar substitute that is also commercially available under the name birch sugar . This sweetener is very dangerous for the dog. You can also recognize xylitol in food by names such as xylitol or E967.

The sweetener triggers an excessive release of insulin, which can lead to the death of the animal. Even small amounts can be fatal. Irreparable brain and liver damage can occur. Symptoms include fatigue and weakness, which can lead to circulatory collapse. Please note that xylitol is found in many sweets, chewing gums and other low-sugar foods. Xylitol is harmless to humans.


The onion is harmful to the dog both raw, dried and cooked. Onion contains sulfur compounds that destroy red blood cells.

The effect can be compared to that of garlic and other types of leek. Here you will find a detailed article with the toxic dose of onions .
