Also offer bearded dragons finely chopped veggies (such as romaine lettuce, zucchini, carrots, etc.), greens (collard, mustard, dandelion, etc.) and fruit (kiwi, banana, mango, etc.). Use healthy, vitamin-rich items; sprinkle the appropriate amount of powdered supplements on these foods, too. Avoid iceberg lettuce because it is not nutritious.
Bearded dragons are omnivorous, meaning they eat both animal and plant matter. They are not usually picky and eat with gusto. Insects, such as crickets and mealworms, should be dusted with a vitamin/mineral supplement and calcium. Dusting can be achieved by placing the insects in a plastic bag with some of the powder, and shaking the bag to lightly coat the insects prior to offering them to your lizards.
Bearded dragons will also eat pinky mice, and a wide variety of nutritionally balanced manufactured diets are available at pet stores, too. Again, if you keep your dragons on sand, offer food on a shallow dish rather than placing it directly on the substrate.
If you keep your bearded dragons on sand, reduce the risk of impaction by offering food on a shallow dish rather than placing it directly on the substrate.
