The days are getting shorter, the furnace is kicking on, and your usually curious bearded dragon has suddenly gone quiet. Less basking, more hiding, and barely a glance at the salad bowl. Is this bearded dragon brumation, or is something wrong?
It could be either. Vets do not fully agree on whether brumation is normal for pet bearded dragons, and illness can look almost exactly the same, so the safest first step is a checkup with a reptile vet.
This guide covers what brumation is, how to tell it apart from illness, how to care for your dragon before, during and after, and when to call the vet.
What Is Bearded Dragon Brumation?
Brumation is a reptile’s version of a winter slowdown. VCA Animal Hospitals describes it as a period when reptiles turn sluggish and inactive, or slip into torpor, during winter or long cold spells.
It is not true hibernation. VCA notes that reptiles stay somewhat active while brumating and may even wake up for a drink.
In the wild, bearded dragons live in inland Australia and brumate during the Australian winter, from May to August, when cooler temperatures and scarce food make them less active. A healthy dragon uses this rest to conserve fat reserves and prepare for the spring breeding season.
Why Do Pet Bearded Dragons Brumate in Fall and Winter?
Your dragon’s body still follows its seasonal instincts. When your home cools down in late fall and winter, some pet dragons slow down too.
VCA explains that if your indoor temperature stays below 60°F (16°C) for several days, or if your dragon lives outdoors, your pet may slip into brumation. Shorter winter days may add to the slowdown, though VCA’s guidance focuses on temperature.
Not every pet dragon will brumate, and that is fine. To double-check your setup, see our guides on the proper bearded dragon habitat and choosing a UVB bulb for bearded dragons.
What Are the Signs of Brumation?
A brumating dragon is basically in low-power mode. According to VCA and Chewy’s vet-reviewed guide (reviewed by Ivan Alfonso, DVM), common signs include:
- Less activity: Slower, sluggish movements and more time sleeping.
- Less basking: More time in the hide and less time under the heat lamp, a pattern also described by Denise Cieri in that Chewy guide.
- Little or no appetite: Your dragon may refuse food entirely.
- Fewer bathroom trips: A dragon that is not eating will usually not poop.
- Darker coloring: VCA notes that lizards may show darker scales and skin.
Is It Brumation or Is My Bearded Dragon Sick?
This is the big one. Many illnesses cause the same lethargy and appetite loss, and reptiles often keep signs of illness hidden.
Vets do not all agree on how normal brumation is for pets. A University of Liverpool Veterinary Practice care sheet says brumation should not happen in captive bearded dragons and always points to some illness. VCA takes a softer view and says a pet kept below 60°F (16°C) for several days may brumate. Either way, a vet check comes first.
VCA warns that if your home stays at a normal 60°F to 70°F (16°C to 21°C), your dragon may not be brumating at all. It may be sick. Its advice is clear: “Rather than assume your bearded dragon is undergoing brumation, have your pet seen by a veterinarian knowledgeable in reptile medicine and surgery to advise you on the best care for your bearded dragon’s condition.”
Use this quick comparison as a guide, not a diagnosis:
| What you see | More like normal brumation | Call your reptile vet |
|---|---|---|
| Activity | Sleepy and slow but still breathing normally | Weak, cannot lift its head, or toes do not grip well |
| Appetite | Eats less or stops eating | Not eating while still awake and basking |
| Body condition | No large drop in weight | Excessive weight loss or a thin, bony look |
| Hydration | May wake up to drink | Sunken eyes or other signs of dehydration |
| Color | Slightly darker scales | A dramatic change to very pale or very dark |
| Breathing and stool | Normal breathing, little or no stool | Trouble breathing, abnormal stool or constipation |
| Age and timing | Healthy adult in late fall or winter | Dragon under 10 months, or slowing down in summer |
If anything in that last column sounds familiar, do not wait it out. Our guide to signs your reptile is sick and needs a vet explains more red flags.
How Should You Prepare Your Bearded Dragon for Brumation?
Preparation means making sure your dragon is healthy enough to rest safely.
- Book a vet check: VCA says dragons fed a poor diet or carrying intestinal parasites can become critically ill when they come out of brumation. Ask your vet about a fecal test for parasites.
- Weigh your dragon: Record a starting weight so you can track changes later. Use a scale kept just for your dragon, away from the kitchen.
- Ask your vet before tapering meals: In Chewy’s vet-reviewed guide, Denise Cieri, founder of HerpHaven Reptile Rescue and Sanctuary, suggests cutting back feedings gradually over the three to four weeks before brumation, then stopping food one to two weeks ahead so the gut can empty. Food left undigested can rot inside a brumating dragon. Check the plan with your vet first.
- Offer a cozy hide: A normal hide with enough room to curl up is fine.
One important caution: do not try to force brumation. The Merck Veterinary Manual says pet reptiles generally should not be put into hibernation, its word for this seasonal rest, unless they are being bred, and that a sick reptile should never be hibernated.
How Do You Care for a Brumating Bearded Dragon?
Once your vet gives the all-clear, let your dragon rest and keep a quiet eye on things.
- Keep fresh water available: Brumating dragons may get up for a drink.
- Skip the food bowl: Other than water, there should be no food sitting in the enclosure.
- Check in daily: Make sure your dragon is breathing and looks otherwise healthy.
- Weigh regularly: Weigh before, during and after brumation. A lot of weight loss means a vet visit.
- Handle as little as possible: It is best to leave a brumating dragon alone most of the time.
- Ask about heat and lights: Keepers differ here, so ask your vet what fits your home.
How Long Does Bearded Dragon Brumation Last?
It varies from dragon to dragon. Chewy’s guide notes that most pet bearded dragons brumate for anywhere from four weeks to four months.
If the slowdown runs longer than that, or your dragon keeps losing weight, check in with your vet.
What Should You Do When Your Bearded Dragon Wakes Up?
Waking up is gradual, so let your dragon set the pace.
- Offer water first: A shallow, lukewarm bath can help your dragon rehydrate after a long rest. Stay nearby while it soaks.
- Wait on food: Keep fresh water out, but hold off on meals for a few days.
- Bring the lights back slowly: If you lowered heat or light, increase it again gradually.
- Watch for weakness: Call your vet if your dragon still seems weak or never fully wakes up.
When your dragon is back to basking and eating, return to its regular menu. Our guide to the bearded dragon diet covers what to feed.
Bearded Dragon Brumation: The Bottom Line
Veterinary sources do not agree on whether brumation is a normal event for pet bearded dragons. VCA describes it as a natural seasonal slowdown a healthy dragon may undergo. The University of Liverpool Veterinary Practice says captive bearded dragons should not brumate at all and that brumation in a pet always signals some illness.
So start with a reptile vet visit, keep fresh water out, weigh your dragon regularly, and never try to force brumation, especially in a sick or young dragon. For a slow winter day, our fun bearded dragon facts are a great read.
And whenever you are unsure, check with your vet.
Frequently Asked Questions About Bearded Dragon Brumation
Not exactly. They brumate, which is a slowdown similar to hibernation, but brumating dragons keep some activity and may wake up to drink.
Wild dragons in Australia brumate during their winter, roughly May to August. Pet dragons in North America tend to slow down in late fall and winter, but they can brumate at other times too.
No. Do not leave food in the enclosure, but keep fresh water available. Talk to your vet if your dragon is losing weight.
Young dragons under 10 months old should not brumate. If a baby or juvenile shows signs of brumation, call your vet.
No. Pet dragons do not need to be pushed into brumation, and it should never be attempted with a sick reptile. Many healthy dragons stay active all year.
Yes. A vet check, including a fecal test for parasites, helps make sure your dragon is healthy enough to rest safely.
