Bearded dragons (Pogona vitticeps) are popular reptile pets known for their unique appearance and docile nature. As responsible pet owners, it is crucial to understand the dietary needs of these fascinating creatures to ensure their overall health and well-being. One question that often arises is whether bearded dragons can eat grass. In this comprehensive guide, we will explore the topic of bearded dragons and their diet, specifically focusing on the inclusion of grass in their meals.

The Natural Diet of Bearded Dragons

Bearded dragons are omnivorous reptiles, meaning they eat both plants and insects. In their natural habitat of arid regions in Australia, their diet consists primarily of insects, such as crickets, mealworms, and roaches, as well as a variety of leafy greens, fruits, and flowers. This varied diet provides them with the necessary nutrients, vitamins, and minerals for their overall health.

In the wild, bearded dragons spend a significant amount of time hunting for insects and foraging for vegetation. This active foraging behavior helps stimulate their natural instincts and promotes physical and mental exercise. Replicating this natural diet and foraging behavior in captivity is essential for their well-being.

The Importance of a Balanced Diet

A balanced diet is crucial for the well-being of bearded dragons. It ensures they receive all the necessary nutrients, vitamins, and minerals required for healthy growth, development, and proper functioning of their bodily systems. While insects form a significant part of their diet, plant matter is equally important to provide essential fiber and other nutrients.

A well-balanced diet for a bearded dragon should consist of approximately 70% plant matter and 30% insects. This ratio may vary depending on the age and specific needs of your dragon. It is essential to consult with a reptile veterinarian or herpetologist to determine the appropriate diet for your pet based on its age, size, and overall health.

The Role of Grass in the Diet

Grass is a common vegetation found in the natural environment of bearded dragons. However, when it comes to including grass in their diet, caution is advised. While bearded dragons may occasionally nibble on grass, it should not be a primary or substantial part of their diet. There are several factors to consider when it comes to feeding grass to bearded dragons.

Nutritional Value and Digestibility of Grass

Grass primarily consists of cellulose, which is a complex carbohydrate that bearded dragons lack the necessary enzymes to digest efficiently. This means that grass does not provide significant nutritional value to them. While they may nibble on grass as a form of exploration or play, it is unlikely to contribute significantly to their dietary needs.

Bearded dragons have a relatively short digestive tract, which is well adapted for digesting insects and easily digestible plant matter. Unlike herbivorous reptiles, such as tortoises, bearded dragons do not possess the specialized gut flora required to break down and extract nutrients from high-fiber vegetation like grass.

Safety Concerns

Another important consideration when it comes to feeding grass to bearded dragons is safety. Certain types of grass, particularly those treated with pesticides or herbicides, can be harmful if ingested by bearded dragons. These chemicals can be toxic and lead to adverse health effects, ranging from gastrointestinal upset to organ damage. Therefore, it is crucial to ensure the grass consumed by bearded dragons is free from any harmful substances.

If you choose to offer grass to your bearded dragon, make sure it is organic and free from any chemicals or contaminants. Avoid collecting grass from areas that may have been sprayed with pesticides, such as lawns or public parks. Instead, consider growing your own organic grass specifically for your dragon’s consumption.

Alternative Vegetation for Bearded Dragons

While grass may not be a suitable staple for bearded dragons, there are several other vegetation options that can be included in their diet:

Leafy Greens

Leafy greens such as collard greens, kale, mustard greens, and dandelion greens are excellent sources of vitamins A, C, and K, as well as calcium. These greens should be a regular part of their diet, comprising approximately 20-30% of their overall intake. They provide essential nutrients and fiber while helping to maintain hydration.

When selecting leafy greens, opt for organic varieties whenever possible. Rinse them thoroughly to remove any potential pesticides or contaminants before offering them to your bearded dragon. Rotate between different types of greens to provide dietary variety and prevent boredom.


Bearded dragons can also consume a variety of vegetables, including but not limited to squash, bell peppers, carrots, and peas. These vegetables offer additional nutrients and add variety to their diet. Chop or grate the vegetables into small, bite-sized pieces to make them easier for your dragon to consume and digest.

It is important to note that some vegetables, such as spinach and broccoli, contain high levels of oxalates and goitrogens, which can interfere with calcium absorption and thyroid function. These vegetables should be fed in moderation or avoided altogether. Consult with a reptile veterinarian to determine the safest and most suitable vegetables for your bearded dragon.


Bearded dragons can enjoy a small amount of fruit as an occasional treat. Suitable options include berries, apples, melons, and mangoes. Fruits should only make up a small portion of their diet, as they are high in sugar. Offer fruit as a special treat once or twice a week, and ensure it is cut into small, manageable pieces.

Edible Flowers

Certain flowers such as hibiscus, nasturtium, and dandelion flowers are safe and provide additional nutrients to bearded dragons. These flowers can be added to their diet in moderation. Make sure the flowers are organic, pesticide-free, and thoroughly rinsed before offering them to your dragon.


While bearded dragons may occasionally nibble on grass, it should not be a significant part of their diet. Grass lacks significant nutritional value for these reptiles, and certain types of grass may contain harmful chemicals. As responsible owners, it is crucial to provide a balanced diet consisting of insects, leafy greens, vegetables, and occasional fruits and flowers.

Always ensure that any vegetation offered to bearded dragons is safe and free from pesticides or herbicides. By providing a diverse and nutritious diet, you can ensure the health and happiness of your bearded dragon companion.
