Why Is My Bearded Dragon Not Eating?
A bearded dragon that stops eating is one of the most common concerns for beardie keepers. In most cases there's a straightforward explanation. Work through the checklist below before assuming illness — the cause is usually husbandry-related.
Common Reasons Bearded Dragons Stop Eating
1. Incorrect Temperatures
This is the most common cause. Bearded dragons need high basking temperatures to digest food properly. A dragon that can't reach an adequate basking spot simply won't eat. Verify temperatures with an infrared thermometer:
- Basking spot surface: 100–110°F (juveniles toward the higher end)
- Cool side: 80–85°F
- Nighttime: No lower than 65°F
If temperatures are off, correct them first and give the dragon 5–7 days to resume feeding before investigating further.
2. Shedding Cycle
Bearded dragons commonly reduce or stop eating in the days before and during a shed. If your dragon's skin looks dull or patchy, wait until the shed is complete before worrying about appetite. See our guide on Bearded Dragon Stuck Shed if the shed doesn't complete cleanly.
3. Brumation
Brumation is a period of reduced activity and appetite that many bearded dragons go through in late fall and winter, similar to hibernation. A dragon entering brumation may eat very little or nothing for weeks to months. As long as the dragon was healthy before brumation and continues to maintain good body condition, this is normal.
4. Stress
New dragons often refuse food for 1–2 weeks while adjusting to a new environment. Other stress triggers include frequent handling, a new enclosure setup, seeing their own reflection, inadequate hides, and being able to see other animals. Give newly acquired dragons at least 2 weeks of minimal disturbance before expecting regular feeding.
5. Inadequate UVB
Bearded dragons require strong UVB lighting to synthesize vitamin D3 and metabolize calcium. A dragon with inadequate UVB may become lethargic and lose its appetite over time. Ensure your UVB bulb is appropriate for the enclosure size, positioned correctly, and replaced on schedule — UVB output degrades before the bulb visibly burns out.
6. Breeding Season
Adult males and females may reduce feeding during breeding season (typically spring). Males may become restless and distracted; females may go off food while developing follicles or eggs. This is normal seasonal behavior in otherwise healthy adults.
7. Illness or Parasites
If husbandry is correct and the dragon has been refusing food for more than 2–3 weeks outside of brumation, or if refusal is accompanied by weight loss, lethargy, abnormal droppings, or other symptoms, a veterinary examination is warranted. Internal parasites such as pinworms or coccidia can contribute to chronic appetite loss, particularly in newly acquired dragons or those with poor body condition.
Quick Checklist
- Verify basking spot surface temperature is 100–110°F.
- Check for signs of shed (dull or patchy skin).
- Consider whether brumation is likely given the time of year.
- Confirm UVB bulb is functioning, positioned correctly, and within its replacement interval.
- Confirm fresh greens are being offered daily.
- Minimize handling and disturbance for 1–2 weeks.
- Try a different feeder insect or fresh greens.
- If none of the above apply and refusal continues, consult a reptile vet.
How Long Can a Bearded Dragon Go Without Eating?
A healthy adult bearded dragon with good body condition can go several weeks without eating, particularly during brumation. However, a dragon that is losing visible weight, becoming lethargic outside of brumation, or showing other symptoms should be seen by a vet. Juveniles have less fat reserve and should not go more than a week without eating without investigation.
What Not to Do
- Don't force-feed — this causes significant stress and can injure the dragon.
- Don't offer live prey and leave it unattended — uneaten crickets can bite a resting dragon.
- Don't assume brumation without ruling out illness first, especially in young dragons.
FAQ
My bearded dragon hasn't eaten in a week — should I be worried?
One week is within normal range for many situations — shed cycles, brumation onset, stress, and breeding season are all common causes. Work through the checklist above. If the dragon is active, maintaining weight, and has no other symptoms, monitor for another week before seeking veterinary advice.
My bearded dragon only wants insects and won't eat greens — what do I do?
This is common in juveniles. Keep offering greens daily alongside insects — most dragons accept them more readily as they mature. Mixing greens with a small amount of squash or bell pepper can help. Avoid offering insects first, as a dragon that has just eaten insects may ignore greens entirely.
