For a definitive answer, you should read the following article:

Bearded dragons are popular exotic pets that love to eat just about anything. They have a high percentage of their diet going towards veggies, which is why they love eating veggies.

Some examples of green vegetables are arugula, bok choy, broccoli, and kale.

Since they eat so many green vegetables, they must love green onions too. Green onions have loads of vitamin K, which is good for blood clotting and making your bones strong.

Arugula is a great source of vitamin C, which can sometimes act as an antioxidant-paying cells from damage.

It’s hard to say whether or not onions are good for bearded dragons. But in order to answer that question and others, please read on below.

Can Bearded Dragons Eat Green Onions? 

Green onions are the same thing as regular chopped onions, but they don’t have as much of a bite to them. Onions should be avoided at all costs in feeding a bearded dragon. 

We can never feed a bearded dragon an onion – because it’s too acidic and would cause complications to its delicate digestive system.

The nutritional facts about onions that matter to people with beards are typically the acidic, calcium to phosphorus ratio, sugar, protein, fat and water. But the fiber is also important!

After some research, you learn that onions have several acidic nutrients. That’s the main reason they’re too acidic.

While humans are in no danger of suffering health problems from an overly acidic diet, the delicate digestive system of bearded dragons can be severely burdened by it. This ultimately leads to major health issues for our favorite lizard.

Baby Bearded Dragons:

No matter what, Bearded dragons cannot eat onions. That includes green onions, spring onions, and any other type of onion. They just can’t eat them.

It is not just the babies who cannot handle onions. Even the adults will be at risk if they consume onions.

It’s pointless if the younger ones eat them too, so we should take extra precautions when handling baby bearded dragons.

The severity of onion toxicity varies depending on the species, including whether or not it’s raw or mature.

The bad news is that onions are potentially toxic to both bearded dragons and lizards. The good news is that your lizard won’t eat them even if you try to feed it!

Can Bearded Dragons Eat Green Onions? Can Bearded Dragons Eat Spring Onion?

In short, bearded dragons cannot eat onions because they belong to the same family. They might have different names, but they have the same properties.

For this reason, it is best to make sure that bearded dragons are never fed any type of onions for their safety. 

One of the ways onions can be harmful to them is that they release slippery fluids that also sit on vegetables like greens.

When beardies eat these vegetables, the juices will make them sick and uncomfortable.

All members of the lizards family have to be careful about what they eat. And one thing that’s off-limits for bearded dragons is green onion leaves.

As it turns out, getting your beard licked may actually be harmful for bearded dragons. Before you allow them to lick your beard, you should consider this.

Are Green Onions Good Or Bad For Bearded Dragons?

Green onions are toxic to bearded dragons and should thus be avoided at all costs.

Bearded dragons should not eat green onions because they are the same as regular vegetables, including regular onions or spring onions.

They are very acidic and have low nutritional value for most beardies. In addition, the sensitive skin of many beardies is unable to handle the high levels of acid present in onion and other vegetables in this category.

Feeding onions to beardies will only bring about medical issues. If you’re caring for a bearded dragon, you may have heard that cooked onions are safe. 

After all, they seem less harmful than raw onions. But that is not the case as far as their properties are concerned. Onions should be called the “forbidden vegetable” for beardies.

5 Reasons Why Bearded Dragons Should Not Eat Green Onions

You’ve probably heard that bearded dragons should never eat onions, such as green onions and any other onion for that matter. Here are some reasons why.

High Acidity:

The acidity in this vegetable is so potent that it will burn the mouth of anyone eating it and of the beardie, who eats leaves with it.

This can also irritate your throat, which will make the beardies stop eating.

Low Nutritional Value:

The onion is safe for humans but toxic to pets.


The high acidity of certain vegetables will cause serious health problems. Serious issues such as heartburn. This will be exacerbated by the beardie’s natural irritability.

Disrupting Digestion:

After the onions are digested, the digestive enzymes won’t have any idea what to do and won’t be active at all.

If the bearded dragon were to drag its ventral scales (underneath its feet) across the ground, they would become quite dirty.

Disproportionate CaP:

The onions have a very unequal amount of calcium and phosphorus.

When we’re balancing calcium and phosphorus for our beardies, the ratio should be 2:1 respectively. However, this doesn’t apply to onions.

Onions introduce too much phosphorus into the body, and that causes a problem with the body’s ability to absorb calcium for the beardies.

What Should I Do If My Breaded Dragons Eat Green Onions?

Even though our bearded friends know to avoid the onion. There are times when they will mistakenly eat them, which might put you in a panic mode. However, we have made a list below.

If it sounds like a situation you’ve encountered, find out how to deal with it.


Some people may not think that a small piece of onion is as harmful as the whole thing.

Therefore, instead of panicking in such situations we can rather pay attention to them and try to notice if there is any change in their behavior.

The below are some of the benefits of a reptile veterinarian:

  1. Convenience 
  2. Safety 
  3. The experience of the vet 
  4. Quality care

If you see that your bearded dragon isn’t active or eating, it’s time to take them to the vet.

Activated Charcoal:

If the reptile has ingested a dangerous toxin, you can use activated charcoal to save its life.

Crush the charcoal and mix it with water before administering it to the reptile as quickly as possible.

To make a paste, mix an equal part of charcoal with one part water.

Then proceed to give that to the beardie via a plastic syringe. The dosage should be based on weight. For 300-450g offer .07ml, for 451-600g offer .09ml, and finally if the weight is above 600-750g offer .13ml.

What Green Vegetables Can Bearded Dragons Eat?

The last few years, we’ve learned that while veggies are good for humans and other mammals, they aren’t great for reptiles. 

That’s why we wanted to share with you some vegetables that we should avoid feeding to our reptile friends! Here are a few of them:

Bok choy:

Our beardies love these greenies. They’re sweet, crunchy and tasty.

Bok choy are a fruit which are full of fiber and contain many vitamins, minerals, and other nutrients. They were even found to be linked with lower rates of heart disease.


Celery is known for having anti-inflammatory properties, which are great because a lot of other vegetables have the opposite effect. This means you’re less likely to get heart diseases and arthritis.

Pets are a huge part of families all over the world, and it’s important to take good care of them.

That includes feeding them nutritious food that helps with fighting off bacteria in their bodies.


Cabbage may seem harmless, but it has a surprising number of calories. The same is true for bearded dragons.

Celery leaves:

These might be a good choice for weight-loss diets. However, they are just a treat for your bearded dragon.

These can make your lizard healthy and provide essential vitamins and minerals, along with fiber.


Kale is a vegetable that’s great not only for us, but also for animals like our dog and little bearded dragons. Kale is full of vitamins A, K, B6, and C. It’s really quite the superstar.

Final Thoughts

Bearded dragons should not be fed onions under any circumstances. The vegetables have a high concentration of acid and thus they will render the digesting enzymes of bearded dragons useless. 

This is because they have a very delicate digestive system and onion is harmful to them.
