Why is my bearded dragon not eating?
A bearded dragon that goes off its food is almost always reacting to its environment, most often a basking spot that's drifted too cool, seasonal brumation, or an upcoming shed. A single missed meal rarely means anything; a run of them, especially with weight loss, does.
Check the basking temperature first
Most appetite loss comes down to heat. A bearded dragon needs a basking surface of 38–42°C (100–108°F) to digest, if it's drifted a few degrees cool for several days, digestion and appetite quietly shut down. Measure at basking height with a digital probe (not a stick-on dial), and check the bulb hasn't aged or the thermostat slipped before anything else.
Is it brumation season?
In autumn and winter, adult dragons naturally slow down and can stop eating for weeks, a hibernation-like state called brumation. It's normal if the dragon is otherwise healthy and its weight holds. Reduced daylight and a cooling room often trigger it, even indoors.
Shedding, stress or a new home
A dragon in shed often refuses food until it's finished. A newly-bought or newly-moved dragon commonly won't eat for days to a couple of weeks while it settles, give it space, keep the setup stable, and don't handle it much. Persistent stress (an over-bright room, a reflection it reads as a rival, an enclosure that's too small) can also suppress appetite.
How long can a bearded dragon go without eating?
A healthy adult can go weeks without harm, which is why brumation is safe. A growing juvenile is different, it should eat daily, so more than a day or two of refusal in a young dragon warrants a closer look at temperature and weight. In all cases it's the weight trend, not any single meal, that tells you whether there's a real problem.
When to see a vet
See an exotics vet if a juvenile refuses food for more than a couple of days, if weight is dropping, or if refusal comes with lethargy, sunken eyes, weight loss, or abnormal stool, and for any refusal that drags on outside brumation season.
One reading rarely tells the story. What matters is whether it's an isolated blip or part of a trend, so look at recent weight, feeding intervals, shedding, temperature and behaviour together.
baskr keeps those records in one place and watches the pattern for you, so you can see whether something has genuinely changed with your bearded dragon, before it becomes a problem.

Why did my bearded dragon suddenly stop eating?+
A sudden change most often means the basking temperature has dropped (a failing bulb or thermostat), a shed is coming, or brumation is starting. Rule out temperature first, then look at the season and shed cycle.
Should I feed my bearded dragon while it's shedding?+
Offer food as normal, but don't worry if it eats less or skips meals during a shed, appetite usually returns once the shed finishes.
Is it normal for a bearded dragon not to eat in winter?+
Yes. Many adults brumate over the cooler months and can go weeks without eating. It's normal as long as weight is stable and the dragon is otherwise healthy, if weight drops, see a vet.
How long can a bearded dragon go without food?+
A healthy adult can safely go several weeks, but juveniles should eat daily. Track the weight trend rather than counting missed meals, steady weight loss is the real warning sign.
