Why Do Bearded Dragons Keep Their Mouths Open?

If you own a bearded dragon, you may notice that they will open their mouth from time to time. This can be due to several reasons, and while it may seem strange, it is a natural behavior for bearded dragons.

1. Thermoregulation

One reason why a bearded dragon will open its mouth is to regulate its body temperature. Bearded dragons are cold-blooded animals, which means they can’t control their body temperature like warm-blooded animals can. To regulate their temperature, they need to bask under a heat source. When bearded dragons bask, they may open their mouths to help cool themselves down. By opening their mouths, they allow cooler air to circulate into their mouth and over their tongue, which helps to lower their body temperature.

2. Stress

Another reason for mouth gaping in bearded dragons is stress. Stress can be caused by several things, including being in a new environment, loud noises, or the presence of other animals. When a bearded dragon is stressed, it may open its mouth, and its body will become tense. If you notice that your bearded dragon keeps opening its mouth and seems stressed, try to identify the cause of the stress and remove it if possible.

3. Respiratory Infection

A bearded dragon that keeps opening its mouth may have a respiratory infection. Respiratory infections are common in bearded dragons and can be caused by a bacterial or viral infection. Symptoms of a respiratory infection include discharge from the nose or mouth, trouble breathing, and lethargy. If you suspect that your bearded dragon has a respiratory infection, take them to a reptile veterinarian as soon as possible.

4. Dehydration

If your bearded dragon is dehydrated, it may open its mouth to pant, which can help reduce their body temperature. Dehydration can occur for several reasons, including not having access to clean water, living in a dry environment, or suffering from a digestive issue. If you notice that your bearded dragon is dehydrated, make sure they have access to clean water and consider misting their habitat to increase the humidity level.

5. Mouth Rot

Mouth rot, also known as infectious stomatitis, is a severe infection that can occur in bearded dragons. The infection is caused by bacteria that enter through cuts or wounds in the mouth. Symptoms of mouth rot include swelling, redness, and sores in the mouth. If left untreated, mouth rot can cause serious health issues and even death. If you suspect that your bearded dragon has mouth rot, take them to a veterinarian immediately.

Conclusion

Bearded dragons are fascinating pets, but they do require some care and attention. If you notice that your bearded dragon keeps opening its mouth, it could be due to several reasons. It’s essential to identify the cause of the behavior and take the necessary steps to address it. Whether it’s providing access to clean water, adjusting the temperature in their habitat, or taking them to a veterinarian, it’s crucial to keep your bearded dragon healthy and happy.
