What Can Dogs Not Eat? 73 Foods You Should Not Feed Your Dog

Here Youll learn about What can dogs not eat 73 Foods you should never feed your dog.

Hi Chris, I’ve spent the past couple of days researching what dogs cannot eat, and I’ve compiled a list of 73 foods so you don’t have too.

There are many foods on this list that are common in a household, and they can be fatal if you dog consumes them.

Milk

High in lactose, dogs lack the enzyme lactase, which is needed to break down the lactose in milk, causing diarrhea.

 Lactose is the sugar in milk that can cause intestinal upset in some people and animals. In dogs, dairy products that contain lactose can cause diarrhea or digestive problems, such as vomiting or constipation. 

Some dogs are more likely to suffer from a reaction to dairy products than others, depending on their unique diet, activity level, and other health factors.

 Some dogs are lactose intolerant, meaning they can’t digest milk sugars normally.

Onions and Garlic

Onions are a common seasoning in many food products, but too much can cause digestive irritation and damage to red blood cells in dogs.

Onions contain a chemical called allicin, which gives them the strong smell and flavor. When the body breaks allicin down, it produces a compound called alloxan, which causes the health problems in canines.

Onions can also cause alloxan levels to increase in dogs, which can damage their red blood cells and cause anemia.

Nuts

Macadamia nuts are high in fat, which can cause weakness, depression, vomiting, tremors and sometimes pancreatitis when the pancreas is inflamed.

 Signs normally appear within 12 hours of ingestion and can last up to 48 hours. 

If your dog has consumed macadamia nuts and you are concerned about their symptoms, contact your vet. They will start treatment while monitoring your dog’s vital signs.

Alcohol

Alcohol poisoning is a condition in which an animal ingests too much alcohol, causing symptoms similar to those of alcohol poisoning. 

These symptoms can include vomiting, diarrhea, abnormal blood acidity, and, in severe cases, failure of the central nervous system and difficulty breathing. 

If the poisoning is not treated, it can be fatal. Alcohol poisoning is much more common in dogs than in cats.

Chocolate

Vomiting, diarrhea, panting, and hyperactivity are just a few of the most common side effects of chocolate toxicity in animals. 

Methylxanthine, the primary compound in cacao seeds, is also known to cause vomiting, diarrhea, and hyperactivity in animals. 

The side effects of methylxanthines are mostly seen in dogs, but they have been known to occur in cats and other pets.

 If you suspect your dog has consumed chocolate, seek emergency veterinary care immediately.

Caffeine

Caffeine is a methylxanthine and toxic to dogs. When consumed in sufficient quantities, it causes abnormal heart rhythm and respiratory difficulties. 

Dogs don’t seem to have a natural tolerance for caffeine, so small amounts can cause a jittery, hyperactive state.

Grapes and raisins

Grape and raisin ingestion has been known to cause serious illness in humans and other animals. While the grapes and raisins themselves are not toxic, ethanol (the alcohol found in fermented food items) can lead to serious complications if a dog ingests it.

 In humans, ethanol exposure has been known to cause kidney failure, and in some extreme cases, it has even led to death. Because of this, it is best if your dog doesn’t eat the grapes and raisins, especially if they are a small breed.

Raw Eggs

Cooked eggs are a great source of protein for dogs. However, raw eggs often contain bacteria such as salmonella and e-coli that can be harmful to pets. 

Dogs are especially vulnerable to the bacteria because they groom themselves less than humans and other animals, which increases the risk of these harmful bacteria being transmitted to the dog through the egg’s yolk. 

Eggs can also carry other bacteria that can cause harmful infections in dogs, such as the tapeworm species Taenia saginata, which can infect dogs’ brains, and the roundworm species Toxocara canis, which can cause serious illness or 

Cheez-Its

Cheez-Its are one of the most popular snacks in the world, but they’re not exactly healthy for you or your dog. 

Unfortunately, many people believe that Cheez-Its are a low-calorie alternative to real cheese, but they’re wrong. 

urn Cheez-Its contain as much fat and calories as many other snacks, such as chips, and they’re also full of white flour and dairy, which can lead to obesity, pancreatitis, and salt toxicity in the long run. 

urn To protect your health and your dog’s, keep Cheez-Its away from them.death.

Raw Meat and Bones

Raw meat, such as chicken or fish, contains bacteria such as salmonella and e-coli, which can be harmful to pets. 

The bones in these meats, such as a chicken bone or fishbone, can also cause choking and puncture your pet’s digestive tract. 

Ingestion of these bones can lodge in the digestive tract and require surgery to remove.

Tomatoes and Potatoes

Tomatoes and potatoes are healthy foods that can also pose risks if consumed in large quantities by dogs. 

Both foods contain oxalates, which can cause abnormalities in the digestive tract, kidneys and nervous system of your dog. 

Green tomatoes are especially harmful, as the large amounts of lycopene they contain can cause serious kidney problems in dogs. 

Don’t give your dog any type of tomato unless you are sure it is the untainted green variety.

Avocados

Avocado plants contain a substance called Pearson, which is in its leaves, fruit seed, and can cause vomiting and diarrhea in dogs. 

Pearson is a fatty acid that is also in human skin, and can cause the same reactions when ingested. Avocado plants are poisonous to dogs if they eat the leaves, fruit seed, or plant matter in the soil. 

However, if a dog eats a small amount of the leaves, the fruit seed, or plant matter in the soil, it can cause diarrhea and/or vomiting.

 So it’s not fatal for dogs, it can make them sick, sluggish, and just not feel good at all. So keep avocados away from your dog, and if you suspect your dog has got into an avocado again, call your vet. 

But if your dog eats, drinks and behaves well, he didn’t have enough avocado to cause a problem, and you should be fine.

Lemons and Lime Juice

The citric acid in lemons is a big problem for dogs. It can lead to gastrointestinal pain (vomiting, diarrhea), muscle tremors, excessive drooling, and inability to stand. 

However, these symptoms usually go away after your dog has stopped drinking the lemonade. 

This is a good sign that you can remove the fermented lemonade from his diet without worrying about any long-term side effects.

Broccoli

Although broccoli is safe for dogs in very small quantities, it is high in fiber, vitamin C, and fat, but also contains isothiocyanate, which can cause mild to potentially severe gastric irritation in dogs. 

Broccoli is a good source of calcium, iron, and vitamins B6 and C, but should be fed in moderation due to the risk of potential gastric upset. 

Dogs are extremely sensitive to the effects of alcohol, so even a small amount of fermented foods, sour dough, or even fermented drinks can cause alcohol poisoning. Talk to your veterinarian about which foods are safe for your dog.

Asparagus

Although it is unsafe for dogs to eat, it is too hard to chew when raw, and when boiled down it loses its nutritional content.

 However, it is safe for dogs to eat cooked asparagus. Like all starchy foods, it is best to avoid giving your dog raw or boiled asparagus. Asparagus is too hard for dogs to chew when raw and boiled, so it poses a choking hazard. Also, asparagus is high in both sugar and starches, which are unsafe for dogs to eat.

Artificial sweetener

Artificial sweeteners have been linked to a wide range of health problems in humans, and now a new study suggests that these chemicals may also pose a risk to dogs.

 Researchers from the University of Missouri discovered that dogs fed artificial sweeteners developed elevated liver enzymes, which is a sign of liver damage.

 In addition, the dogs experienced an increase in blood clotting, a sign of a blood disorder. The canine sweeteners under examination were Equal and Sweet’N Low.

Corn on the Cob

On the cob, corn is dangerous to dogs. It’s the cob that can cause a blockage in your dog’s intestines. So keep corn off the cob and make sure your pup doesn’t eat any. If your dog does eat corn on the cob, contact your vet immediately.

Cheese

Cheese can be a tasty addition to dog foods, but if your dog eats too much, he might experience some unpleasant side effects.

 diarrhea, bloating, gas, and constipation are some of the side effects that can occur when cheese is consumed in large amounts.

 However, if your dog has a history of chewing on tires, hair, and other items, he might accidentally eat a significant amount of cheese without realizing what it is.

 In this case, a dog food that is high in protein may not be the best choice for your dog.

Bacon

The high-fat content of bacon can lead to a number of problems for dogs, including gastrointestinal issues and even the development of the canine pancreas.

 In the case of dogs, this is referred to as pancreatitis, which is an inflammation of the pancreas. 

This can be life-threatening if not treated, so it’s important to take note of the signs of pancreatitis in dogs and act quickly to get them the treatment they need. 

Bacon is a common cause of pancreatitis in dogs, and it is also a common cause of other types of digestive problems in dogs, such as diarrhea and vomiting.

THC

THC, the psychoactive ingredient in marijuana, is bad for your dog. While there are many benefits of marijuana for humans, it’s a different story for your furry friend. In fact, THC can be quite dangerous for dogs. It can cause symptoms similar to those in humans, such as anxiety, vomiting, and even seizures.

Chewing Gum

Some popular sugar-free candies and treats for dogs contain a sweetener called xylitol, which is extremely dangerous to dogs.

 Xylitol is a common sweetener found in many baked goods and candies, including those marketed as “healthy” for dogs.

Apples

Apple flesh is harmless to dogs, but apple seeds are poisonous. Amygdalin, a chemical in the seeds, breaks down into cyanide, a toxic chemical that kills cells. 

There have been cases in humans where ingesting apple seeds have caused cyanide poisoning. 

Not only do dogs eat apple seeds, but they pass them in their poo, which is how dogs get poisoned in the first place.

Bread Dough

When ingested the dough expands in the stomach, stretches and pulls the stomach wall slightly inward, which is probably not what you want. 

This is called a gastric dilation volvulus (G.D.V.) and can be quite fatal. The longer the dough is allowed to sit, the more toxins it will have consumed and the more likely it will be to twist the stomach in on itself. 

This is why unbaked dough is poisonous for dogs.

Ice cream

The most common cause of diarrhea in dogs is lactose intolerance. The lactose in dairy products, such as ice cream, is difficult for dogs to digest. 

In many cases, the diarrhea that results from lactose intolerance is the result of too much dairy in the pet’s diet. 

This occurs when dogs eat more dairy than their bodies are capable of handling.

Candies

Candy is delicious, but for your dog’s teeth, it can be a bad choice. Candy is high in sugar, which can lead to obesity, and sugar can damage your dog’s teeth.

 In addition, many candies are made with xylitol, which we have already talked about. Even worse, many candies are dyes and other fillers that can cause serious health problems.

Peaches, Plums, or Apricots

The pits of peaches, also known as peach pits, are the most dangerous part of the peach. 

They can cause intestinal obstruction in dogs and humans, and contain cyanide, which is poisonous to both. 

However, the edible parts of the peach are safe for dogs to eat. They contain pectin, which is a gelling agent that is beneficial to the body, and is used as a dietary supplement in humans to help with cholesterol, diabetes and other health issues.

Caraway seeds

Caraway seeds are high in the monoterpenes carvone and limonene. These compounds, along with essential oils, cause a mild intestinal upset and cause vomiting and diarrhea in dogs. 

Care needs to be taken in feeding caraway seeds to dogs, as it can trigger an immune response that can cause allergies. 

In people, eating large amounts of caraway can cause an upset stomach and diarrhea.

Marijuana Edibles

Marijuana edibles contain THC, the chemical that makes you feel “high”, but dogs do not react the same way humans do when they consume edibles. Without treatment, they can enter a coma and even die. 

edibles can be even more deadly if they contain other substances, such as chocolate, that dogs may not like. This is called “fear vomit”, and it can be very dangerous to your pet.

French Fries

French fries are usually very salty and contain many unhealthy added ingredients, making them dangerous for dogs. 

It is important to know that the worst type of French fries are the ones that are very high in saturated and trans fats and sodium. 

This is because these types of fries often have the highest amount of unhealthy added ingredients, making them the most difficult for your dog to digest. 

The best French fries are the ones that are made from unprocessed potatoes, which contain only healthy unsaturated fats and a small amount of salt.

Mushrooms

Some mushrooms are poisonous to dogs, while others are safe to eat. 

There are, however, a few mushrooms that are poisonous to dogs even though they may not seem dangerous; these are called hallucinogenic mushrooms. 

Even though these mushrooms may not look like they are going to be bad for your dog to eat, the risk of your dog eating these mushrooms and being poisoned is always there. 

The symptoms of a dog eating a poisonous mushroom may not be evident for a day or more, which is another danger of these mushrooms.

Human Medicine

The medicine your vet prescribes is made to help your pet feel better. 

But there are some pretty common ingredients in prescription pet medicine that can be dangerous for your dog if you give them the wrong dosage.

 Acetaminophen, ibuprofen, and is often found in painkillers and can be fatal if given to your dog.

 Here are some of the more common ingredients to look out for: Ibuprofen, acetaminophen, aspirin, and caffeine.

Spices

Pennyroyal oil is a common spice used in many human recipes.

 It has a strong, pungent odor that is similar to that of black pepper. However, pennyroyal oil is much stronger, and can cause extreme irritation to the skin. 

If your dog comes into contact with pennyroyal oil, it can cause severe irritation, burning, and swelling.

Jello

The sweetness in jello isn’t natural, which is what makes it so bad for dogs.

the added sugars to artificial sweeteners, such as xylitol, which is extremely toxic to dogs

Cake

The excess sugar content can lead to weight gain and obesity, because the cake is full of sugar, which is not healthy for your dog.

Weight gain and obesity lead to other serious health complications, such as arthritis, heart disease and diabetes.

Pickles

Pickles contain saltwater brine, vinegar and other spices, which is where the high sodium content comes from and can contain ingredients toxic to your dog.

Hummus

Hummus contains garlic, which we’ve already covered as poison to dogs. It also contains lemon juice, which is an acidic citrus fruit, and includes psoralens that can cause poisoning.

The list of side effects is indigestion, discomfort, abdominal pain, vomiting, and diarrhea.

Grapefruit

Grapefruit has a high concentration of essential oils, and a compound called psoralen found in grapefruit, it is toxic to dogs.

The side effects are vomiting, diarrhea, and behavioral changes, such as depression, or photosensitivity.

Donuts and Bagels

Donuts are coated in white powdered sugars, and your dog’s blood sugar level will suddenly spike. If you feed him regularly, he may be at risk of weight gain and canine obesity.

Fat and Meat Trimmings

A large amount of fat can cause an overload of the digestive system and cause an inflammation of the pancreas

Beef Jerky

When your dog eats beef jerky, he may be at risk of sodium ion poisoning. Garlic poisoning. Onion poisoning. Xylitol poisoning can lead to choking, stomach upset, cavities, obesity and hormonal changes

Chicken Nuggets

Chicken nuggets are loaded with fat, which leads to rapid weight gain. Obesity weakens the heart

Mold

Mold can cause lung and respiratory problems, damage to the gastrointestinal tract, serious digestive problems, allergic reactions, and neurological problems such as tremors and seizures.

Oreos

Oreos have chocolate that we have covered and know is toxic to dogs. Oreos also contain loads of fat and sugar

Pop Tarts

Pop-tarts can give your dog an upset stomach, which can lead to vomiting and diarrhea.

Some Pop-Tarts contain artificial sweetener xylitol, which can be fatal

Pretzels

Some pretzels contain raisins, which are toxic to dogs, and also contain Xylitol, which is also toxic to dogs.

Wasabi

Wasabi is very hot and spicy, which can cause a burning sensation in the nose and mouth due to the hot fumes of wasabi.

some other side effects of wasabi

Stomach pain

Abdominal discomfort

Diarrhea

Gas

Excessive thirst

Vomiting

Tortillas

Tortillas are high in carbohydrates, which can lead to diabetes or blood sugar spikes in your dog.

Plain tortillas are unlikely to seriously harm your dog if fed in small quantities on a rare occasion.

If your dogs are allergic to gluten or wheat, they should not have tortillas

Waffles

Waffles are bad for dogs. They’re high in fat and calories, which can lead to weight gain and health problems. 

Most dogs don’t have the necessary enzymes to break down the fat in waffles, which can cause pancreatitis, a serious and sometimes fatal disease of the pancreas. 

Bread is better for your dog, and can be a good training tool when used correctly.

Animal Crackers

All animal crackers, whether plain or with ingredients such as cheese, should be avoided by dogs. Many animal crackers are made with xylitol, an artificial sweetener that’s extremely toxic to dogs. Choosing plain animal crackers is safest for your dog. Still, many commercial animal crackers contain xylitol and chocolate, two ingredients that are dangerous for dogs and should be avoided.

Bay Leaves

Bay leaves, also known as bay laurel, are leaves from the bay tree that are used as a spice and flavoring. 

They contain eugenol, which is an organic compound that is responsible for the characteristic smell and flavor of bay leaves.

 In small amounts, eugenol is considered to be safe for humans. However, eugenol can cause serious problems in dogs.

Chamomile

Chamomile flowers contain bisabolol, chamazulene, anthemic acid, and tannic acid. 

While these molecules are fewer in dry chamomile, it is still not suggested to give to dogs. It can cause mild intestinal upset and cause vomiting and diarrhea in dogs. 

Care needs to be taken in feeding caraway seeds to dogs, as it can trigger an immune response that can cause allergies.

Takis 

Takis are filled with preservatives and harmful ingredients that can hurt dogs. To begin with, spicy foods are generally not recommended since they irritate the dog’s digestive system. 

But, even though takis are filled with preservatives and harmful ingredients, they are still a major source of calcium and protein for dogs. They are also a good source of dietary fiber and iron.

Dairy

Feeding your dog dairy is not a matter of life and death, and can actually be a nutritious treat if fed in small amounts. 

However, dogs cannot digest dairy products, as well as most humans, can. As a result, dairy can cause digestive issues in dogs, including diarrhea and constipation. 

For this reason, it is important to feed dairy to your dog in moderation.

Sorbitol 

Xylitol is a sweetener found in many processed foods and is even added to some chewing gums. 

Xylitol is used as a sugar substitute because it has little effect on blood sugar. However, like other sugars, xylitol is not a nutritional necessity and can cause problems in large quantities.

 In dogs, xylitol is readily absorbed, and may cause gastrointestinal irritation.

Rhubarb 

Rhubarb is a vegetable commonly used in baked goods. But did you know that rhubarb can also cause stones in your dog’s kidneys? 

Rhubarb is high in oxalates, which can form calcium oxalate kidney stones. These can block your dog’s urine flow, causing intense pain and damage to your dog’s kidneys.

Oregano, Marjoram and Mint

A large percentage of dogs that are given oregano or marjoram oil tablets will experience gastrointestinal problems.

 This is because of the essential oils found in the products. These essential oils cause irritation and damage to the intestines.

Pepperoni

Pepperoni, like many spicy foods, is bad for dogs. The high salt and fat content can contribute to heart disease, obesity, and even pancreatitis. Furthermore, many pepperoni contain garlic or onion powder, both of which can be detrimental to a canine’s health.

Persimmon 

Persimmon is a tree that is poisonous to dogs. If you put persimmon in a bowl of water, it will poison you as surely as poison itself. Persimmon contains a poison known as saponins. The poison causes the droplets of the saponin to be too numerous and carry about the others.

Poppy Seeds

Poisonous poppy seeds are toxic to dogs. A small amount of poppy seeds can kill a dog within 2 hours.

Salami 

Dogs are eating salami. But because of the way it’s made, it’s bad for them. It contains too much fat. Too much salt.Then, garlic is toxic.
