What fruit And Vegetables is Bad For Dogs? – 25 Dangerous Vegetables For Dogs To Eat

Fruits and vegetables can rev up essential nutrients in both humans as well as our pet dogs, however, the dog’s digestive system is not designed to process plant-based dietary foods.

Just a little too much of veggies or fruits ingestion by your pet dog could mean stomach upsets, diarrhea and to the extreme death of your pet from poisoning.

There are a lot of vegetables that we eat with our dogs that are safe for them to eat. While we would like to share with our dogs every plant food humans eat, some vegetables are not so safe for dog consumption.

Before conclusively ruling out all of the vegetables as not safe for our dogs to eat, its vital to understand where the“dangers” of vegetables and fruits ingestion by your pet come from.

Despite all fruits and vegetables being edible and palatable to the human body, the same vegetables may also contain harmful natural chemical compounds in their seeds, chlorophyll, fruit skins, thorns, prickles, and generally anything that has a detrimental effect on the health and wellbeing of the dog. 

That is why we have listed the 25 of the human staple food that can quickly turn out to be dangerous vegetables and are not recommended for your dogs to ingest in large quantities.   


can dogs eat beetroots

Sunday roast meals in our household can not go without including Beetroot as a part of our veggie salads. And we love beetroots as they are a good source of vital vitamins and minerals like fiber, folate, vitamin C, manganese, and potassium. 

The trouble for our family makeup is that it includes our beloved pet dog called Tess! 

While there is all evidence backed publications supporting that beetroot ingestion can rev up vitamins and minerals for your dog’s digestive and immune system. There is also a great deal of concern for plant-based food when ingested in a larger amount for your dog.

So, Is it OK for dogs to eat beetroot?

Yes! Dogs can eat beetroots as long as the amount of the portion is moderated. 

Beets are said to contain essential minerals that promote healthy skin and coat for your dog. While others would want to make, it look as if it’s rare for dogs to become allergic to beetroot ingestion; the truth is the digestive system of the dog is not designed for plant-based food.

1. Mushrooms

Can dogs eat mushrooms

Mushrooms are a huge part of our day to day food we eat, whether its breakfast grilled mushrooms or pan-fried mushrooms, as humans we seem not to have enough of it! 

While mushrooms are safe for humans to eat, they are not so safe for dogs to indulge themselves as they seem to want to join in on the breakfast table.

 Dogs eating mushrooms does not go down well because some mushrooms do contain toxins that are known to cause serious kidney damage or failure to the dogs. Beyond that, mushroom toxicity also causes liver problems in dogs. 

Though this sounds alarming, for the record, dogs and humans both suffer from mushroom poisoning as there are different kinds of mushrooms, and within the huge list of these fungus plants, some are harmful for people as well as dogs. 

Except that dogs are more susceptible to suffer mushroom toxicity to most human edible types of mushrooms than the poisonous mushrooms in the wild. 

The good news for humans is that the mushrooms that make it to the store are checked so do not worry about food poisoning. Sadly dogs are not on the list. 

So, Can dogs eat store-bought mushrooms? Yes! Dogs can eat store-bought mushrooms. However, moderation of the amount of mushroom consumption each time your dog eats is vital here!

 Too much of anything is not suitable for the dog’s digestive system and mushroom ingestion is no different.

But, if your dog has accidentally eaten yard mushrooms, you need to take him to the nearest veterinary in your local area.

2. Green Potatoes

The same nutritious cooked potatoes we all love are incredibly harmful to dogs when eaten fresh. 

And dogs left alone while we are away at work can often find their way into our dry food pantry where they can mischievously munch on green potatoes, which sadly contain substances called Oxalates. 

Oxalates can have a heavy impact in the alimentary canal as they can affect digestion. Your dog may excrete stools have been partially digested or not digested are all. 

On top of that, Oxalates can cause kidney problems as well as the nervous system.

As green potatoes are not safe for dogs, the same applies to potato peelings.

3. Green Tomatoes And Leaves

Tomato leaves are widely eaten as a vegetable, and for humans, they come packed with phytonutrients the body needs. However, this is where the good story of tomato leaf veggie ends as this plant’s leafy juices contain a substance known as solanine which is very harmful to dogs.

With tomato plants, even the stem contains this harmful compound too. The same can also be said for green unripened tomato which is also toxic but only when it has the green skins. And when they are ripe, your dog can enjoy them with you.

Some symptoms after ingestion include; vomiting, tremors and urine in blood. 

 Note: Do not serve tomatoes to your dog if you have mixed them with onions. This brings me to my next point;

4. Onions

 When it comes to onions, no matter how they are prepared, they are generally harmful to dogs. This is because they contain disulfides and thiosulphate. 

These substances, when ingested by your dog, can cause severe red blood cells damage which leads to anemia. And for this reason, make sure to always keep onions away from your dog’s diet.

5. Peppers

Green peppers are a popular condiment and veggie on our tables! The trouble is numerous dogs enjoy eating human food where peppers were added. 

And its no secret that a lot of pet owners like their cooking to include peppers, to the point that they add it to every meal. 

Now the question here is, if your dog is eating human food or scraps, are peppers safe for dogs to eat? 

Yes! Dogs can eat green peppers in smaller quantities. However, if you snooze and let your dog eat too much raw bell peppers, expect stomach upset and stinking farts, which can eventually escalate into diarrhea and, in some cases, severe vomiting also.

And the only type of peppers considered to be safe for dog’s ingestion is bell peppers. 

The rest of any other peppers should not be fed to your dogs, although green peppers have low calories and vitamins C and beta carotene, which help in reducing toxins in the body.

6. Garlic

7. Corn on a cob

Corn can be a good source of Iron and Potassium. It also contains fiber which helps the digestive system for the dog.

14. Cassava

These roots are safe for both dogs and humans to eat and they can be prepared in various ways- cooked, dried, powdered or even eaten raw. 

Cassava is mostly classified based on its sweetness or bitterness in which case, the sweeter the cassava, the healthier it is.

23. Arnicas
