We often feed human foods in small amounts to our canine friends. Besides, we know all human foods cannot be good for dogs; some can even be fatal. So, what food can kill dogs instantly?

Fruits, like grapes, raisins, avocados, etc., are hazardous for dogs. Again, nuts, like macadamia nuts and walnuts, are not good for dogs. Alcohol, chocolates, artificial sweeteners, and many junk foods are also not for dogs. Usually, we suggest not adding salt and spices to dogs’ foods. It is because they are also toxic to dogs.

Anyway, this article below will give you a proper list of those food items that your paw friend should never eat.

What Food Can Kill Dogs Instantly?

Dogs usually rely on dog foods to fulfil their nutritional needs. Sometimes, we offer them some human foods, especially healthy ones. But unfortunately, some human foods, which are healthy for us, can be poisonous to dogs. So stay certain of the food items that can pose health threats to our four-legged friends.

Grapes And Raisins

Raisins are the dried version of grapes. If grapes are harmful to dogs, so are raisins. One of the main reasons why dogs can’t take grapes is because they are citric fruit. They may go through kidney failure after eating a moderate amount of grapes and raisins. Whereas, a few amounts of grapes and raisins can cause vomiting, diarrhoea, and abdominal pain.

According to reports, a handful of grapes and raisins can kill dogs. Therefore, dogs should not only avoid grapes and raisins but also every item that includes these ingredients.


No vets will recommend feeding coffee, tea, or cocoa powder to dogs as they contain caffeine. Caffeine is a stimulant for the nervous system, which speeds up the heart rate. This particular ingredient can have hazardous side effects on our canine friends. Dogs can’t withstand even a small amount of caffeine.

After consuming caffeine, you may see your dog giving unwanted reactions after 2 to 4 hours. You may see him feeling excessively thirsty, restless, vomiting, having watery poop, and so on.

Sometimes caffeine can be the reason for a dog’s death. This is because it makes their heart rhythm abnormal, which usually occurs due to an overdose of caffeine.


There is a toxin called persin that is present in many food items. Unfortunately, avocado also contains this toxin, which makes it unsafe for dogs to consume. This can inflame a dog’s pancreas and cause him abdominal pain, among other fatal diseases.

Avocado is also an unsafe food for dogs because of its pit. It can cause talking hazards for our canine friends.

Not only the avocado’s flesh and pit but also every part of the avocado plant can harm a dog with its toxin called persin.


Xylitol is used as an artificial sweetener in candies, gums, and other baking items. We also call it birch sugar or sugar alcohol. This artificial sweetener can cause xylitol poisoning in dogs. When a dog eats any food with this artificial sweetener, his blood sugar level will drop. You may see this reaction after 30 minutes of xylitol consumption.

The initial symptoms could be weakness and vomiting. If the amount of xylitol is high, the dog can go through seizures, tremors, and even a coma.


As said before, caffeine and xylitol are harmful to dogs. Meanwhile, chocolate contains both of these ingredients. Besides, it has a chemical called theobromine, which is more harmful than caffeine and xylitol. Also, it has cocoa powder, which is another unsafe ingredient. It means almost all ingredients in chocolate are toxic to dogs.

Well, a moderate amount of chocolate can lead your dog to vomiting, dehydration, watery poop, etc. Again, a bar of whole chocolate can lead to serious issues, like seizures, tremors, heart diseases, and so on.

Yeast Dough

Uncooked yeast dough is another harmful food for dogs. When dogs eat it, it goes inside the stomach and expands. This can cause dogs to bloat, which can twist the stomach. That’s why eating large amounts of uncooked dough can kill dogs instantly.


Alcohol is not only bad for humans but also dogs and other mammals. Humans can take it in small amounts, but dogs should avoid it completely. Your dog will show adverse reactions within one hour of alcohol consumption. This can be depression, tiredness, vomiting, etc. Too much of its consumption can cause seizures, lung failure, and coma.

Along with alcohol, any beverage that includes alcohol is toxic to dogs. Some dogs even die from alcohol poisoning. So keep it away from your paw friend.


Whenever it comes to feeding vegetables, fruits, nuts, etc., to dogs, vets restrict the canned ones to feeding them. This is because canned foods found on the market contain salt and other ingredients. This means you can’t allow your dog to have salt. 2 to 3 grams of salt can be risky for them.

A moderate amount of salt can increase the blood pressure in dogs and result in dehydration. However, too much or regular consumption of salt can lead to tremors, cerebral oedema, and neurological disorders in dogs.

Macadamia Nuts

Sometimes, almonds, peanuts, and cashew nuts can be safe for dogs in small amounts when they are healthy enough. In contrast, macadamia nuts are not safe for dogs, even in small amounts. They may go through macadamia nut poisoning, which occurs within 12 hours of consumption. The symptoms can be vomiting, depression, weakness, hyperthermia, and so on.

Onions And Garlic

Both onions and garlic can damage the red blood cells in dogs. They usually enhance the flavour of foods. It means any ingredient used to increase the flavour of foods can be toxic to dogs. Such as onion powder, onion flakes, chilli flakes, etc. The common symptoms that dogs show after eating them are vomiting, diarrhoea, and anaemia.
