How Long Can a Bearded Dragon Go Without Food: And Why Do They Sometimes Dream in Color?

How Long Can a Bearded Dragon Go Without Food: And Why Do They Sometimes Dream in Color?

Bearded dragons, scientifically known as Pogona, are fascinating reptiles that have become popular pets due to their docile nature and relatively low maintenance. One of the most common questions among bearded dragon owners is: How long can a bearded dragon go without food? This question is not only crucial for understanding their survival mechanisms but also for ensuring their well-being in captivity. However, the answer is not as straightforward as one might think. It depends on various factors such as age, health, environment, and even the dragon’s individual personality. Let’s dive deep into this topic, exploring the science, the myths, and the quirky behaviors of these remarkable creatures.


The Science Behind Bearded Dragons and Fasting

1. Metabolic Rate and Energy Storage

Bearded dragons are ectothermic, meaning they rely on external heat sources to regulate their body temperature. This characteristic significantly influences their metabolic rate. In warmer environments, their metabolism speeds up, requiring more frequent meals. Conversely, in cooler conditions, their metabolism slows down, allowing them to survive longer without food.

Adult bearded dragons can typically go 1-2 weeks without food, provided they have access to water. Juveniles, however, have higher metabolic demands due to their rapid growth and should not go without food for more than 2-3 days. Prolonged fasting in young dragons can lead to stunted growth and other health issues.

2. Brumation: The Reptilian Hibernation

Brumation is a period of dormancy similar to hibernation, commonly observed in bearded dragons during colder months. During brumation, their activity levels drop significantly, and they may refuse to eat for weeks or even months. This is a natural behavior and not a cause for concern, as long as the dragon is healthy and well-hydrated.

3. Fat Reserves and Survival

Bearded dragons store fat in their tails and bodies, which serves as an energy reserve during periods of food scarcity. A well-fed dragon with ample fat reserves can survive longer without food than one that is underweight. However, relying solely on fat reserves for extended periods can lead to malnutrition and organ damage.


Factors Influencing How Long a Bearded Dragon Can Go Without Food

1. Age and Life Stage

  • Hatchlings and Juveniles: These young dragons require daily feeding to support their rapid growth. Going without food for more than a few days can be detrimental.
  • Adults: Mature dragons can tolerate longer fasting periods, especially during brumation or when adjusting to a new environment.

2. Health Status

A sick or stressed bearded dragon may refuse to eat. Underlying health issues such as parasites, infections, or metabolic bone disease can significantly reduce their ability to survive without food. Regular veterinary check-ups are essential to ensure your dragon remains healthy.

3. Environmental Conditions

  • Temperature: Cooler temperatures slow down their metabolism, enabling them to go longer without food.
  • Lighting: Proper UVB lighting is crucial for their digestion and overall health. Inadequate lighting can lead to appetite loss.

4. Hydration

While bearded dragons can survive without food for extended periods, they cannot go without water for long. Dehydration can occur within 2-3 days, leading to severe health complications. Always ensure your dragon has access to fresh water.


Quirky Behaviors and Myths

1. Dreaming in Color

While it might sound whimsical, some reptile enthusiasts speculate that bearded dragons dream in color. This theory stems from their ability to perceive a wide range of colors, which plays a role in their hunting and social behaviors. Whether or not they dream in color remains a mystery, but it’s a delightful thought to ponder.

2. Food Preferences

Bearded dragons are omnivores, but their food preferences can vary widely. Some dragons are picky eaters, refusing certain vegetables or insects. Others may develop a fondness for unusual items, such as flowers or fruits. Understanding your dragon’s preferences can help ensure they receive a balanced diet.

3. Stress and Appetite Loss

Bearded dragons are sensitive creatures. Changes in their environment, such as a new enclosure or the presence of other pets, can cause stress and lead to appetite loss. Providing a stable and comfortable environment is key to maintaining their eating habits.


Practical Tips for Bearded Dragon Owners

  1. Monitor Their Weight: Regularly weigh your dragon to ensure they are maintaining a healthy weight. Sudden weight loss can indicate underlying health issues.
  2. Offer a Varied Diet: A balanced diet of insects, vegetables, and occasional fruits is essential for their well-being.
  3. Maintain Proper Habitat Conditions: Ensure their enclosure has the right temperature gradient, UVB lighting, and humidity levels.
  4. Hydration is Key: Mist their enclosure regularly and provide a shallow water dish for drinking and soaking.
  5. Consult a Veterinarian: If your dragon refuses to eat for an extended period, seek professional advice.

Frequently Asked Questions (FAQs)

1. Can a bearded dragon die from not eating?

Yes, prolonged fasting can lead to severe health complications and even death, especially in young or sick dragons. Always monitor their eating habits and seek veterinary care if necessary.

2. How can I encourage my bearded dragon to eat?

Try offering a variety of foods, ensuring their habitat conditions are optimal, and minimizing stress. If appetite loss persists, consult a veterinarian.

3. Is it normal for a bearded dragon to stop eating during brumation?

Yes, it is entirely normal for bearded dragons to stop eating during brumation. However, ensure they remain hydrated and monitor their weight.

4. What are the signs of dehydration in bearded dragons?

Signs of dehydration include sunken eyes, wrinkled skin, lethargy, and reduced urination. Provide fresh water and consider soaking your dragon in shallow water to rehydrate them.

5. Can bearded dragons eat human food?

While some human foods, such as leafy greens and certain fruits, are safe for bearded dragons, others can be harmful. Avoid feeding them processed foods, dairy, or anything high in sugar or salt.


In conclusion, understanding how long a bearded dragon can go without food requires a holistic approach, considering their biology, environment, and individual needs. By providing proper care and attention, you can ensure your scaly companion thrives and continues to enchant you with its unique behaviors—whether it’s dreaming in color or simply basking in the sun.
