Can Bearded Dragons Eat Leeks?

Leeks are typically considered safe for Bearded Dragons to eat, despite the fact that several vegetables from this family can harm them. Leeks are a member of the Allium genus, usually referred to as the onion family. This indicates that they share traits with onions and garlic, which Bearded Dragons cannot have because they are harmful to them. However, the green part of the leek is safe for them. When introducing leeks to your pet’s diet, it’s important to remember that moderation is vital.

Benefits of Leeks for Your Bearded Dragon

Your Bearded Dragon should only eat the green part of the leeks since it’s the most nutritious. Leeks contain vitamin C, which can help boost your Bearded Dragon’s immune system and repair injured tissues. They also have Vitamin A, which supports the Bearded Dragon’s eyesight, bones, and teeth, and vitamin K which supports bone development and is essential to aid blood clotting. The calcium in leeks is vital for growth and bone development, and other essential nutrients include manganese, iron, and copper.

Leeks are also a good fiber source that can improve digestion and prevent constipation in Bearded Dragons. They have a high-moisture content which helps keep your Bearded Dragon hydrated. While leeks can be a healthy addition to your Bearded Dragon’s diet, they should only be served occasionally.

Risks of Feeding Your Bearded Dragon Leeks

Feeding your Bearded Dragon’s leeks can also have some drawbacks that owners should be aware of, especially if your pet enjoys eating leeks. If you feed your Bearded Dragon the white part of the leek, they can get sick. Leeks contain moderate to high levels of a substance called oxalates. The oxalate compounds combine with calcium which can affect its absorption.

Oxalate-rich foods should be consumed in moderation since excessive consumption may cause calcium oxalate crystals or kidney stones. Furthermore, some Bearded Dragons may be more sensitive, causing gas or gastrointestinal distress with new foods in their diet.

You can feed your Bearded Dragon raw or cooked leeks, but again, only feed them the green part. The important thing is that you cut them up into small pieces equivalent to the size of the gap between their eyes.

  • It is best to serve fresh leeks, which are preferably organic and free from chemicals. Before preparing the leeks, rinse them thoroughly to remove any dirt or chemicals. You should then remove the tougher layers on the outside and cut off the end with the roots.
  • You can then chop the leeks into small pieces that are small enough for your Bearded Dragons to consume. As we mentioned before, a general guide is to cut them to the same size as the gap between your Beardie’s eyes. They should also be thin so that they are easier to chew and swallow.
  • Once you have your chopped pieces of leek ready, place a few in the feeding bowl or enclosure. Monitor your pet while they eat, and watch for any signs of digestive problems, including bloating, diarrhea, or changes in appetite. If any problems occur, stop feeding the leeks and contact your veterinarian.
  • You can feed leeks to your Bearded Dragon once or twice a month as a treat. Most of your Bearded Dragon’s food should consist of suitable insects, leafy greens, and other vegetables to ensure they eat a balanced diet.

The Ideal Bearded Dragon Diet

To ensure a balanced diet, feed various fruits, vegetables, and insects. Only 10%–20% of the plant material should be fruits, and 80–90% should be leafy green vegetables. It’s best to select only leafy greens that are high in calcium. While calcium is necessary for your Bearded Dragons to build their bones, too much can be harmful, so moderation is key.

Your Bearded Dragon can enjoy leafy greens like kale, spinach, broccoli, and Swiss chard. Avoid light green veggies that are high in fiber and deficient in vitamins, such as iceberg lettuce and celery. Insects, including Dubia roaches and worms, are also nourishing and will maintain the health of your Bearded Dragons.

Generally, an adult Bearded Dragon’s diet should consist of roughly 80% plant-based material and 20% insects, however depending on their age this is reversed in young beardies 80% to 20% insect to plant based. It is always best to talk to your exotics veterinarian about your Bearded Dragon’s diet.

Bearded dragons can eat leeks occasionally but should only be fed the green section. Leeks can benefit your Beardie’s diet with various vitamins and plenty of moisture, but they can also be risky due to the oxalates that can cause calcium problems. If you choose to feed your pet leeks, they should be cut up into small pieces, and you should monitor your lizard for any reactions. Before adding leeks or anything new to your Bearded Dragon’s diet, talk to your veterinarian.
