Can Dog Eat Cauliflower (and Other Harmful Veggies)? A Brief Guide!


Sometimes there is a debate between dog owners about which vegetables are suitable for dogs and are not recommended. And, it must be said, opinions on this matter are quite contradictory. Foods such as cauliflower, cucumber, tomatoes, bell peppers and many others are often overlooked.

In reality, it's much simpler when it comes to the selection of vegetables for the canine family.

If a vegetable (or any other food) is unsuitable for the dog, the body will quickly react with allergies and hair problems.

You can do this by gradually adding them to your dog's diet and seeing how his body responds so that you can assess whether or not the food is digestible.

Don't blindly believe everything written in many publications on the subject of "what's good and what's bad". It's all individual. If your dog tolerates a so-called "harmful" food, there's no need to deprive him of the opportunity to get extra vitamins. But, of course, there has to be a measure for everything.

If your dog doesn't itch and is in good spirits, then you're doing the right thing, and the vegetables you're feeding him are suitable for him!

Let's take a closer look at can a dog eat cauliflower and other vegetables, how often and in what form.


Are vegetables really necessary in a dog's diet?

In general, dogs are carnivores by nature, and therefore the central part of their diet, around 70-80%, should consist of foods containing protein, such as meat, fish, eggs and dairy products. The remaining percentage is made up of vegetables and a small quantity of cereals.

It is not unusual for every dog owner to find bits of undigested vegetable in his stool. It is because dogs do not have the enzymes needed to break down the vegetable fibre. For this reason, vegetables and leafy greens are poorly digested by your pet's body.

You might ask, "So why do dogs need vegetables if their stomachs can't digest them?

Vegetables are a source of non-digestible fibre and are needed by the animal's body as slow carbohydrates, a source of coarse dietary fibre that creates the right prebiotic environment and helps better digest meat.

Although the body does not digest fibre, it is excellent for regulating the intestines and flushing out excess cholesterol. Vegetables are also rich in vitamins and micronutrients that every living organism needs.


Which vegetables are safe to give your pet?


Many pet owners are afraid to give cauliflower to their dogs. Cauliflower is more digestible than any other cabbage. It has less roughage than, for example, white cabbage, so it is easy to digest and doesn't irritate the mucous membrane of the stomach. It is perfect for gastrointestinal diseases. In liver and gallbladder disease, only those vegetables are recommended, which increase bile secretion and promote regular emptying of the intestines. These include cauliflower.


Pumpkin improves digestion, reduces gastric acidity, regulates stool and treats constipation. Pumpkin is an excellent antioxidant and helps prevent helminths.

Courgette is a good source of potassium, calcium, beta-carotene and folic acid. It is usually given raw but can also be baked.


Cucumbers are perfectly safe for dogs. They are rich in complex organic substances, which play an essential role in metabolism. Potassium in cucumbers improves heart and kidney function.

Bell peppers

Bell peppers contain beta-carotene and several useful B vitamins. They are also rich in potassium and calcium, iron and iodine, magnesium, phosphorus, fluorine, copper, zinc and sodium.


Carrots are rich in vitamin A and beta-carotene, which help to improve eyesight, reduce the risk of tumours. Raw carrots are also suitable for cleaning plaque on teeth, reducing the number of pathogenic bacteria in the mouth and foul odour and exercising the jaw muscles. But be careful; some dogs may be allergic to carrots.

Vegetables that are controversial about their benefits or harms

Some vegetables are not strictly forbidden. However, some are not healthy enough, and others are not suitable for all dogs and can cause serious harm to your pet's health.


Beetroot is rich in potassium, antioxidants and folic acid. However, it is a fairly allergic vegetable. If your dog is not allergic to beetroot, a small amount will do the job. Large quantities can cause diarrhoea.


Tomatoes are usually included in the list of foods not recommended for dogs. If fed in large quantities, they can cause upset stomach, heart muscle malfunction, heart palpitations, muscle weakness and tremors. However, in small amounts, it is quite a healthy vegetable. Tomatoes serve as an excellent plaque preventative. They are a potent antioxidant and useful against inflammation.

Therefore, if the dog is not allergic to tomatoes, they should be included in the diet in reasonable quantities. Fresh, ripe tomatoes are safest.


Some dog owners have undeservedly put this vegetable on the list of not recommended. It contains isocyanate, a substance that is toxic to dogs and can cause death. But for it to do any harm, it must be given in large quantities every day.

Broccoli is rich in vitamins C and K, and it surpasses all other cabbage plants in vitamin A content. It is in frozen cabbage that all the valuable vitamins last much longer.


White cabbage is an excellent source of sulphur, calcium, potassium, phosphorus, beta-carotene and vitamins A, B and C. And, it must be said, many pets love it because you can crunch on it and nibble on the hard bits of leaf.

But it's not recommended for dogs to eat large amounts of fresh kale because it causes gas, upset stomach and intestinal pain. On the other hand, you can spoil your dog once in a while with boiled or braised cabbage.

In what form should you give your dog vegetables?

This is where dog breeders differ. Supporters of the Barf system, for example, say that as the animal's body is unable to digest fibre, vegetables should be pureed in a blender.

You can generally alternate between chopping in a blender, grating, dicing or slicing. Larger diced vegetables are chewed up and thereby also shredded. Also, chewing fresh raw vegetables additionally helps to prevent plaque formation.

However, this is not suitable for small puppies or dogs being switched from dry food to organic food. Little puppies simply can't chew properly and will want to choose something tastier (meat, of course), leaving the vegetable platter in his bowl.

Not all vegetables are recommended to be heat-processed. Some are better given raw. This preserves their valuable vitamins and minerals.
