Bearded Dragon Not Eating: Causes and What to Do
When a bearded dragon skips pellets or insects for several days, it's understandably worrying. Fortunately, most cases of appetite loss are caused by environmental or seasonal factors rather than disease. Still, a few warning signs do mean a vet visit is needed, so it's important to tell them apart.
Common causes
- Insufficient temperature: a low basking spot temperature impairs digestion and reduces appetite. The basking spot should generally sit around 38-42°C.
- Brumation (a hibernation-like slowdown): in adult bearded dragons, reduced activity and appetite in fall/winter is a natural occurrence.
- Pre-shed appetite loss: it's also common for appetite to temporarily drop right before a shed.
- Stress from environmental change: rearranging the enclosure, a new tankmate, or loud noise can also be a cause.
What to check at home
- Measure the basking spot temperature directly with a thermometer (guessing by hand is inaccurate).
- Check UVB light exposure time (10-12 hours a day) and the bulb replacement schedule (usually every 6 months to 1 year).
- Look for accompanying changes in stool, eyes, or body weight.
When to see a vet
If body weight has visibly dropped, your dragon is lethargic and limp, or stool abnormalities (diarrhea, blood) appear alongside the loss of appetite, this may not be simple seasonal appetite loss. If they go a full 2 weeks or more without eating at all, or you can see them getting thin, it's safer to have an exotic vet check for parasites or a metabolic condition.
