  • Allow heavy breathing for cooling by providing a heat gradient in the enclosure.
  • Seek veterinary care if heavy breathing persists or worsens over time.


Bearded dragons are one of the most popular lizard pets. Their gentle nature, manageable size, and longevity make them ideal for reptile enthusiasts. As pet owners, we want to make sure our bearded dragons stay healthy and thriving for years to come.

One common concern that crops up is increased breathing rate or heavy breathing in a bearded dragon. This noticeable change in respiratory pattern is often the first indicator of an underlying issue. Identifying the root cause early allows us to take appropriate action to resolve it.

This comprehensive guide will analyze the key reasons why a bearded dragon may start breathing heavily. By understanding the triggers, we can modify their environment or seek veterinary care to address any health conditions. With proactive management, our beloved pet lizard can go back to feeling comfortable and content.

Why Is My Bearded Dragon Breathing Heavily?

There are a few main reasons why a bearded dragon may breathe heavily or rapidly. Let's evaluate each one in detail:

Is Heavy Breathing in Bearded Dragons Normal?

Mild to moderate heavy breathing can be normal in bearded dragons in certain situations. When they are stressed or regulating their body temperature, increased respiratory rate helps supply more oxygen to muscles and tissues.

However, if heavy breathing seems excessive, continues for extended periods, or is accompanied by other symptoms, it may signify an underlying health issue.


One of the most common reasons for heavy breathing in bearded dragons is stress. As prey animals, bearded dragons have a strong fight or flight instinct. Stress activates their adrenal glands and triggers the release of hormones like adrenaline.

Rapid breathing sends more oxygen to the muscles to help the body prepare for intense physical activity. It enables the bearded dragon to fight back or escape a perceived threat.

Some ways to identify stress breathing include:

  • Onset of heavy breathing is sudden and acute in response to a trigger.
  • No other symptoms like mouth gaping or nasal discharge.
  • Breathing returns to normal when removing the stressor.

To manage stress-related heavy breathing, identify and eliminate the source of stress. Maintain a familiar environment and handle the bearded dragon gently. Avoid overhandling when they seem agitated.

Temperature Regulation

Bearded dragons are cold-blooded reptiles native to Australia's desert climates. They rely on external heat sources and behaviors to maintain their optimal body temperature between 95-110°F.

When bearded dragons get too hot, they will breathe heavily with an open mouth. This allows increased air flow over the moist tissue in the throat and mouth to provide an evaporative cooling effect.

Temperature-related heavy breathing may occur if:

  • The enclosure is too hot due to faulty heating.
  • Hot basking spot lacks a cooler retreat area.
  • Ambient temperatures exceed the optimal range.

To help manage heating-related heavy breathing, ensure the enclosure has a temperature gradient. The basking area should be 95-110°F while the cool end remains around 70-80°F. Proper temperatures allow bearded dragons to thermoregulate by moving between zones.

Respiratory Infection

Heavy or rapid breathing accompanied by other symptoms can signal a respiratory infection. Respiratory infections are commonly caused by bacteria, fungi or parasites. Stressed immune systems and improper humidity are contributing factors.

Symptoms that point to a respiratory infection include:

  • Labored breathing with mouth open or gaping
  • Wheezing or clicking sounds
  • Bubbling around the mouth and nose
  • Discharge from the mouth or nose
  • Loss of appetite
  • Lethargy
  • Darkening of color

A University of Florida study found that symptoms typically progress from mild to severe over 2-3 weeks if left untreated. Respiratory infections require veterinary treatment with antibiotics, antifungals and supportive care.

FAQs about Heavy Breathing in Bearded Dragons

What does heavy breathing in bearded dragons look like?

Heavy breathing is visible as rapid movements of the throat and chest as a bearded dragon takes quick shallow breaths with an open mouth. Breaths may seem exaggerated or labored.

Is it normal for bearded dragons to breathe fast?

It's normal for bearded dragons to breathe slightly faster when active or adjusting their temperature. But consistent fast breathing or heavy panting is usually linked to stress, overheating or illness.

How many breaths per minute are normal for a bearded dragon?

On average, a healthy resting bearded dragon takes 12-18 breaths per minute. Breathing rates above 50 breaths per minute are considered abnormally rapid.

Can bearded dragons breathe fast when sleeping?

No, it is not normal for bearded dragons to breathe rapidly when asleep. Heavy breathing while inactive likely indicates high stress levels or health issues like respiratory infection.

When should I be concerned about heavy breathing in my bearded dragon?

Contact a reptile veterinarian if heavy breathing is persistent over several hours or worsens over 24-48 hours. Also seek medical care if breathing heavily is accompanied by discharge, appetite changes or lethargy.

What causes respiratory infections in bearded dragons?

Bacteria, fungi and parasites can all cause respiratory infections in bearded dragons. Contributing factors include poor husbandry, inadequate heating, high humidity and a weakened immune system due to stress or poor nutrition.

How is a respiratory infection treated in bearded dragons?

A veterinarian will prescribe antibiotics, antifungal or antiparasitic medication tailored to the cause of infection. Supportive care like hydration therapy, nutritional support and proper heating is also important.

How can I prevent respiratory infections in my bearded dragon?

Prevent respiratory infections through proper husbandry. Ensure appropriate heat gradients, free airflow, low humidity, clean environment, healthy diet, and minimal stress. Annual exams catch issues early.

When should I take my bearded dragon to the vet for heavy breathing?

Contact your reptile vet promptly if heavy breathing persists over several hours or is accompanied by lethargy, appetite changes, discharge or mouth gaping. Do not delay medical care.


Heavy or rapid breathing in our bearded dragon can certainly be alarming for pet owners. However, understanding the common underlying causes can help us respond appropriately. Mild temporary breathing changes are often linked to stress and temperature regulation. But persistent heavy breathing or breathing issues combined with other symptoms require veterinary diagnosis and care.

With attentive observation of our bearded dragon's health and behavior, we can identify problems early and take action. Ensure proper husbandry and avoid undue stress in their environment. Seek veterinary advice whenever concerned about respiratory health. Addressing problems quickly allows us to get our pet bearded dragons back to perfect health
