Foods You Should Never Feed Your Dog

Yeast Dough

9. Yeast Dough

Your dog loves the smell of bread and pastries just as much as you do. Sadly, they are not able to enjoy these delicious treats, because their stomach is simply not equipped well enough to digest the yeast that is used in breads and pastries.

Yeast is composed of microorganism, and like all microorganisms, it is basically alive. Give it a little sugar and some warm water, and you can watch yeast come to life! The problem is that it continues to grow slightly, even after baking, until it reaches a point when it is fully digested by your body.

Unfortunately, your dog does not have enzymes that are strong enough to destroy yeast, which results in serious digestive problems, such as bloating, and even tangled intestines.

There are many other treats that your dog can enjoy, so don't risk causing your pet any discomfort!

Common symptoms:

  • Bloating
  • Gas
  • Painful yelping
  • Vomiting

Raw Meat, Eggs and Bones

10. Raw Meat, Eggs and Bones

You may like to think of your dog as a domesticated wolf, but you would be far from the facts of evolution to think this way. Although dogs biologically belong to the same family that wolves do, dogs are domesticated animals, and have been so for about 3,000 years. In the process of domestication, the dog's entire body has changed to better adapt to its human counterpart.

There are two main reasons why raw meat is not good for your dog:

  1. Your dog does not have the same strength in its digestive acids that a wolf has, meaning that your dog cannot break down the entire piece of raw meat that it is given. This results in the meat continuing through the digestive system in its raw state, possibly rotting in the process before it finally exits the body.
  2. It is very difficult to determine the state of raw meat, because a lot of it contains salmonella, bacteria, and other pathogens which are dangerous for your dog.

Stick to foods that are specially prepared for your dog, or make sure to thoroughly cook any meat that you plan to give your pet.

Common symptoms:

  • Vomiting
  • Nausea
  • Digestive problems
  • Weakness

Avocado

11. Avocado

There is a bit of a debate going on when it comes to feeding your dog avocados. We should mention right away that vets do not generally recommend that you feed your dog avocados, regardless of the fact that some people continue to do so anyway. Here is why:

Avocados have a toxic chemical within them called persin. This chemical is found in the leaves, the skin of the fruit, and especially in the large seed of the avocado. As the avocado fruit grows, persin is released from all these areas, and may easily enter into the flesh of the fruit.

If your dog were to eat this toxin, it would almost immediately suffer from poisoning. Depending on the breed of the dog and its previous health condition, this single intake of persin could be lethal. Please protect your pet by not feeding it avocados!

Common symptoms:

  • Diarrhea
  • Vomiting
  • Painful squeling
  • Weakness
  • Pale gums

Chocolate

12. Chocolate

Chocolate is one of the most serious causes of death in dogs. There is nothing cute about giving your dog chocolate, regardless of how healthy your dog may be or what breed it is.

Not only does chocolate contain caffeine, which we already mentioned as being very bad for dogs, but it also contains large amounts of the alkaloid theobromine.

Humans are able to digest theobromine, but dogs cannot metabolize it. Not only that, this alkaloid will remain in your dog's body for the next 72 hours, causing anything from great discomfort to full body poisoning. Sadly, your dog doesn't know that chocolate is lethal for them, which is why the best way to prevent anything bad from happening is to keep chocolate hidden as far away from the dog as possible.

Your dog may experience seizures, the breakdown of its nervous system, kidney failure, and even death.

Common symptoms:

  • Shaking
  • Nausea
  • Seizures
  • Kidney failure
  • Respiratory failure
  • Death

Persimmons

13. Persimmons

There are a few different components as to why your dog should not eat persimmons.

Firstly, the sugar in persimmons is too high for your dog's health. It will cause a sudden increase in the dog's insulin levels, which often results in shaking, nausea, and weakness. But the sugar isn't the only problem.

The seeds of persimmons contain cyanide. This chemical compound is lethal for both humans and dogs, depending on the amount of it that is digested. Humans have a much higher tolerance for cyanide, but only in the sense that we are not likely to suffer after eating fruits such as persimmons or apricots. However, dogs have an extremely low tolerance of cyanide, and even the smallest intake can mean big trouble.

A dog that has eaten cyanide will suffer from almost instant poisoning, the severity of which depends on the amount eaten and the dog's current health.

Common symptoms:

  • Vomiting
  • Shaking
  • Weakness
  • Seizures
  • Drop in temperature

Peaches, Plums and Apricots

14. Peaches, Plums and Apricots

Peaches, plums and apricots belong to the same family of fruits as persimmons, meaning that they will have the same negative effect on your dog's health. This refers especially to the pits that are found in the center of these fruits, which contain the chemical compound cyanide.

Even if you remove the pit and decide to feed your dog only the flesh of the fruit, your pet would still experience great discomfort. Even the smallest amount of cyanide will cause serious stomach problems, diarrhea, and vomiting.

None of these fruits are a natural part of your dog's diet, so there is not reason to feed them to your dog in the first place. Vomiting is most likely to occur as a result, because the dog's body is trying to get rid of as much of the toxins as possible. Please do not put your pet through this and never feed your dog these fruits.

Common symptoms:

  • Vomiting
  • Diarrhea
  • Weakness
  • Drop in body temperature

Gum

15. Gum

There is no natural component of a chewing gum that would ever make a dog owner want to feed this to their pet. However, dogs are curious creatures and if they find a chewing gum lying around, they would probably want to taste it.

However, gum is very dangerous for your dog for two main reasons:

  1. We already mentioned the dangers of Xylitol, which is the plant-derived sweetener that is extremely toxic for dogs. Much of it is found in chewing gum, where its purpose is to reduce the acidic properties that are found in traditional sugar. However, when eaten by dogs, it is immediately toxic and often causes liver failure!
  2. Dogs would not know how to properly eat chewing gum anyway, because even humans do not swallow this product. If a dog were to swallow a gum, it would suffer from additional problems affecting the bowels and its digestive system.

Keep gum away from your pet!

Common symptoms:

  • Vomiting
  • Shaking
  • Pale gums
  • Bloated stomach
  • Painful squeling

Sugar

16. Sugar

Dogs love sugar just as much as we do, and can even develop an addiction to it! Their taste buds are curious and love delicious foods, but sadly, a dog is not aware that sugar is dangerous for their health.

Sugar has the same negative effect on dogs as it does on humans, except in much larger doses. Sugar can make your pet gain weight, causing joint problems and blood problems. Sugar also disrupts the natural insulin levels that your pet's body is used to, causing your dog to feel unwell. Like humans, dogs can also develop diabetes, which can be lethal if left untreated.

Your dog does not need any unnatural sugars in its system. It will receive everything it needs from generic dog food and granules, so please do not feed any sugar foods to your dog!

Common symptoms:

  • Weight gain
  • Nausea
  • Diabetes
  • Vomiting
  • Fatigue

Salt

17. Salt

Small amounts of salt are crucial for the body to function. However, the body will retain all the salt it needs from healthy, savory foods. The process is the same in both humans and dogs, and as long as salt levels are kept to a minimum there will not be any visible problems.

However, if the body takes more salt than it needs, it will begin undergoing the process of dehydration. Dehydration is dangerous for the dog's entire system, because it thickens the blood, causing it to run poorly, which in turns means that not enough oxygen is reaching the crucial parts of the body. One of the first organs to be affected by this will be the brain, which is dangerous because it could cause lasting nerve damage.

If your dog eats too much salt, it will experience shaking, vomiting, and fainting. If this happens, you must take him to a vet as soon as possible!

Common symptoms:

  • Vomiting
  • Weakness
  • Shaking
  • Fainting
  • Reduced cognitive function

Moldy Food

18. Moldy Food

The reason why mold is mentioned here is because many people, sadly, think that they can simply give their dog leftover food in order to save money on actual dog food. This is a horrible thing to do, and will cause your dog to become extremely ill.

Mold is made up of microorganism, which multiply at a rapid pace. They are a normal part of our world, but they are absolutely not meant to be ingested. If eaten, your dog can experience great stomach discomfort, vomiting, the development of dangerous bacteria, and lasting intestinal damage.

Mold is also found in dog food that has passed its expiration date, as well as the garbage can that your dog is frequently curious about. Keep your environment clean, so that your pet doesn't have to suffer!

Common symptoms:

  • Nausea
  • Vomiting
  • Shaking
  • Painful squealing

Corn on the Cob

19. Corn on the Cob

Although some vegetables are good for your dog, corn is not one of them. It has very little nutritional value, and in agriculture is mostly used to quickly increase the weight of poultry and farm animals.

Additionally, corn also has a number of allergens, which are dangerous for the dog and can cause it to have rashes, seizures, and serious intestinal problems.

People sometimes give their pets corn on the cob because they think that it will make a good chew toy. Not only is the actual corn a problem, but also, if your dog eats the cob it will find it very difficult to digest. The corn cob has no nutritional value, and will only cause your dog to experience vomiting and diarrhea.

Common symptoms:

  • Vomiting
  • Nausea
  • Digestion problems
  • Diarrhea

Blue Cheese

20. Blue Cheese

Other than the fact that it is a dairy product, which means that your dog should not be eating it by default, there are a few other reasons why blue cheese is an absolute no-no when it comes to choosing treats for your pet.

Blue cheese has incredibly complex enzymes within it, because the enzymes were added additionally to the milk that was used to make the cheese. These enzymes, combined with roquefortine c, which gives blue cheese those recognizable spots, is a substance that dogs are very sensitive to.

If your dog eats blue cheese, its metabolism will not be able to break it down, which means that your dog will experience serious vomiting. If your dog is elderly or already has health problems, then the after effects of blue cheese could be even more severe.

Common symptoms:

  • Vomiting
  • Diarrhea
  • Shaking
  • Bloating
  • Seizures

Apple Cores

21. Apple Cores

Small amounts of cleaned, raw apples will not cause a serious problem for your pet. However, if your pet were to get a hold of the apple seed, they would experience a very bad day of stomach problems.

Like many fruits which need a way to defend themselves from other animals eating them, apple seeds also contain cyanide, the toxic chemical compound that can be lethal for both humans and animals.

Dogs are likely to eat apple seeds if the owner has not taken care when de-seeding the apples, or if the dog sniffs through the garbage can for apple remains.

In either case, your pup will have serious stomach pains, bloating, and vomiting as a result. Please do not feed your dog apple cores, and make sure to get rid of the seeds properly so that your dog won't find them.

Common symptoms:

  • Vomiting
  • Shaking
  • Diarrhea
  • A drop in temperature

Pizza

22. Pizza

Pizza is a combination of things that dogs should absolutely not be eating. Everything from the dough to the toppings is dangerous for your dog, and yet many people do not realize how serious the situation could become.

The pizza dough is made from flour, yeast, a lot of salt, and oils. None of these things are healthy for your dog, and none of them are easily digested. The toppings often include sausages, fermented olives, and a number of different vegetables, including onions, which we already mentioned are bad for your dog.

Dogs that eat pizza will suffer from a combination of problems, which will include bloating, vomiting, a painful abdomen, or even seizures.

Please stick to dog food when feeding your dog!

Common symptoms:

  • Vomiting
  • Diarrhea
  • Bloating
  • Nausea
  • Decreased cognitive function
  • Seizures

Banana

23. Banana

Bananas in small amounts can actually be healthy for your dog. As is the case for humans, bananas are good for lining your dog's stomach and intestines with a protective layer, which then helps to digest other foods.

Small amounts of bananas which have been properly peeled should not cause any harm to your dog.

However, you must remember that bananas are still full of sugar. It doesn't matter that it is healthy fruit sugar, too much of it will still make your dog's insulin levels jump, causing nausea and a higher risk of diabetes.

Please only feed your dog the amounts that are recommended by the vet, so that your dog does not experience the negative effects of too much sugar.

Common symptoms:

  • Vomiting
  • Shaking
  • A drop in temperature
  • Onset of diabetes

Chamomile

24. Chamomile

Bizarrely, the same herb that humans have used for hundreds of years to soothe stomach ailments is also toxic for your dog!

Scientists have not yet uncovered which part of the chamomile flower is the one that is so toxic for dogs, but the bottom line is that if your dog ingests chamomile, it will inevitably suffer from vomiting and a very painful abdomen.

Some have speculated that chamomile has a number of allergens that dogs are not able to handle, while others simply feel that tea in general is not something that dogs should be drinking. There have also been small differences when it comes to dog breeds, sizes, and their age.

The best decision that you can make is to not give your dog any chamomile. If your pup has any stomach problems, there are many safe medicines that your vet will recommend to help.

Common symptoms:

  • Bloating
  • Vomiting
  • Nausea
  • Shaking
  • Allergic reaction

Rhubarb

25. Rhubarb

Rhubarbs are a serious cause of concern if eaten by your dog. The part of the plant that is used for cooking is highly acidic for dogs, and will instantly cause stomach problems.

Even worse, however, is the fact that the leaves of the rhubarb plant are extremely toxic for your dog. People often buy rhubarbs and carelessly leave them in the kitchen, but if your dog gets a hold of it, there will be serious problems to deal with.

Additionally, some people enjoy growing rhubarbs in their garden. If you own a dog, do not grow this plant, because your dog may end up chewing the leaves and seriously poisoning itself.

Common symptoms:

  • Nausea
  • Vomiting
  • Diarrhea
  • Drop in temperature

Tomatoes

26. Tomatoes

Tomatoes are an acidic vegetable, which is already a problem when it comes to the health of your dog. Dogs do not handle acid very well, and will likely have instant health problems if they eat such foods.

However, another problem with tomatoes is that they have solanine, a glykoalkaloid poison, which in some cases can even cause stomach upsets in humans. If a dog were to eat a tomato, it would suffer from poisoning and the inflammation of its stomach lining, which is of course very painful.

The dog will need to be taken to a vet immediately, because it would quickly suffer from vomiting, and possibly even seizures.

Make sure to keep tomatoes away from your dog so as not to accidentally cause them any harm.

Common symptoms:

  • Vomiting
  • Seizure
  • Diarrhea
  • Weakness

Potatoes

27. Potatoes

Another surprising cause of concern in a dog's diet are potatoes. Although they seem harmless on the outside, potatoes actually have the same glykoalkaloid poison, solanine, that is found in tomatoes.

In fact, every part of a potato is dangerous for your dog, and this includes both the potato skin and its leaves. Dogs are not able to handle these chemicals, and will instantly feel bad after eating them. A boiled potato will not have as high of a solanine content, but because people often leave potato peels in the garbage, the dog can easily find them if it feels curious.

Please keep your dog safe by getting rid of all traces of raw potatoes from your home as soon as possible, so that your dog doesn't suffer from vomiting and nerve problems.

Common symptoms:

  • Vomiting
  • Lack of cognitive function
  • Diarrhea
  • Shaking
  • Weakness

Citrus Fruits

28. Citrus Fruits

Sadly, all citrus fruits are bad for your dog. This is true for every part of the citrus fruit and also includes citrus juices, regardless of whether they are store-bought or homemade.

Lemons, oranges, and grapefruits have a number of toxins that can be lethal for dogs, especially if they are eaten in high quantities. They contain psoralen compounds and aromatic oils, which your dog has no way of digesting. Although the smell of the citrus fruit may be tempting for your dog, eating it would result in acid poisoning, vomiting, and rapid weakness.

People can often be seen giving citrus fruits to their dogs as a joke to make them react to the taste, but even these small amounts can be dangerous. Love your pet, don't make fun of it.

Common symptoms:

  • Vomiting
  • Seizures
  • Shaking
  • Weakness

Licorice

29. Licorice

Licorice may seem like a fun treat for humans, but it is an incredibly toxic food for dogs.

Licorice is made of a number of different processed ingredients, none of which are good for your dog. However, one of the biggest issues is the compound glycyrrhizin, which is toxic for dogs. They have no way of digesting this compound, which results in sudden abdominal inflammation and incredible pain.

Dogs will try to sniff out anything they can find in the house, especially when they are left alone, so it is crucial that here are no sweets lying around for them to eat. Unfortunately, the dog is not aware of the fact that if it does eat licorice it will quickly begin to vomit and even lose control of its muscles.

Common symptoms:

  • Muscle weakness
  • Vomiting
  • Diarrhea
  • Shaking
  • Seizures

Fast Food

30. Fast Food

Fast food may seem like a quick treat for your dog, especially when he is staring at you passionately to give him some! However, you will need to resist those puppy dog eyes if your dog's health is to take priority.

Fast food has no nutritional value for anyone, especially not your dog. It is made from processed meats, fried in deep oil, covered in sauces which are also made from processed ingredients, and has an incredible amount of salt. Your dog is better than that, and does not deserve such a poor treat for being your best friend!

If you find yourself in a situation where your dog is begging for food, you will be a much better owner if you swap the unhealthy food for a delicious, healthy dog treat. It will stop your dog from developing health problems such as weight gain, diabetes, and problems with digestion.

Common symptoms:

  • Weakness
  • Nausea
  • Vomiting
  • Diarrhea
  • Diabetes
  • Heart problems
