Is my bearded dragon brumating?

Brumation is a natural, hibernation-like slow-down that many bearded dragons go through in autumn and winter, sleeping more, hiding, eating little and sometimes digging in. It's normal in a healthy adult that holds its weight; the way to separate it from illness is a steady weight trend and the absence of other symptoms.

What brumation looks like

As the days shorten and the room cools, an adult dragon may become sluggish, sleep far more, retreat to a hide or a cool corner, dig or try to burrow, and eat little or nothing for weeks. It can last from a few weeks to a couple of months. Reduced daylight and a cooling room trigger it even indoors, and the behaviour can come on gradually or fairly suddenly.

When brumation is normal

Brumation is healthy in an otherwise-well adult that is holding its weight and shows no other symptoms. The dragon should still look well when it does rouse, clear eyes, normal colour, no laboured breathing. Keep the setup running as normal rather than switching everything off; let the dragon choose to warm up if it wants to, and offer water. Don't try to force it awake or force-feed it through a genuine brumation.

Telling brumation from illness

This is where the weight trend earns its keep. A brumating dragon sleeps and fasts but holds its weight roughly steady week to week; a dragon that's slowing down and losing weight is not simply brumating and needs looking at. Weigh weekly on the same scale, and treat symptoms like sunken eyes, weight loss, laboured breathing, discoloured or runny stool, or a persistently black beard as signs of something beyond a seasonal slow-down.

Juveniles usually shouldn't brumate

Growing juveniles are putting energy into development and typically shouldn't brumate, a young dragon that goes off food and turns lethargic is more likely to have a husbandry or health problem than to be brumating. Check the basking temperature and UVB first, and watch the weight closely. Any young dragon that stops eating and loses weight, or shows other symptoms, warrants a vet rather than being written off as a seasonal slow-down.

When to see a vet

See an exotics vet if a supposedly brumating dragon is losing weight, or if the slow-down comes with sunken eyes, laboured breathing, abnormal stool, a persistently black beard or weakness, and be especially cautious with juveniles, who usually shouldn't brumate at all.

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.

Related questions

How do I know if my bearded dragon is brumating or sick?+

Weight is the tell. A brumating dragon sleeps, hides and fasts but holds its weight week to week and looks well when roused; a sick one loses weight or shows sunken eyes, laboured breathing or abnormal stool. Weigh weekly on the same scale and watch the trend.

At what age or time of year do bearded dragons brumate?+

Brumation is a seasonal response to shorter days and cooler rooms, so it typically starts in autumn or winter in adults. Growing juveniles usually shouldn't brumate, so a young dragon slowing right down is more likely a husbandry or health issue worth checking.

Should I feed my bearded dragon while it's brumating?+

Don't force-feed a dragon that's genuinely brumating, undigested food sitting in a cool gut can cause problems. Keep water available and let it choose to warm up and eat if it wants to, and confirm it's brumation rather than illness by watching the weight.

How long does bearded dragon brumation last?+

Anywhere from a few weeks to a couple of months, varying by individual. As long as the dragon holds its weight and shows no other symptoms it can safely ride it out, steady weight loss, though, means it's not simply brumation and warrants a vet.
