How long do bearded dragons live? As pets, usually about 7 to 15 years. VCA Animal Hospitals says captive dragons can live about 7 to 12 years with proper care, and the RSPCA says their lifespan is usually 10 to 15 years or more. Where a dragon lands in that range depends mostly on its setup, diet and how early problems are noticed. Below: what tends to shorten a dragon’s life, how they change with age, and the signs that mean a vet visit rather than waiting.

Bearded dragon lifespan at a glance

SourceWhat it says
VCA Animal HospitalsCaptive bearded dragons can live about 7 to 12 years with proper care.
RSPCALifespan is usually 10 to 15 years or more, so they are “quite a commitment”.

The two ranges overlap rather than disagree: a well-kept dragon commonly reaches its teens, and a dragon kept without proper UVB, heat or diet often does not. Treat any single number as a rough expectation, not a promise.

Life stages: what changes as a dragon ages

StageRough ageWhat you usually notice
Hatchling / baby0–3 monthsRapid growth, frequent sheds, eats insects several times a day.
Juvenile3–12 monthsStill growing fast; diet gradually shifts toward more greens. This is when metabolic bone disease is most often seen.
Adult1–2 years and upGrowth slows and weight becomes more stable; dragons reach sexual maturity at 1 to 2 years. Many brumate seasonally.
Older adultLater yearsGradually less active, may eat less and lose some muscle. Changes should be slow, not sudden.

For size and weight by age, see our bearded dragon growth chart or the free growth check.

What shortens a bearded dragon’s life

Most of the common problems vets describe come back to the enclosure and the diet. VCA notes that bearded dragons are “reasonably hardy animals” if they are well looked after. The usual culprits:

  1. Missing or weak UVB lighting. Without UVB, a dragon can’t make vitamin D3 and can’t absorb calcium, leading to metabolic bone disease (MBD). VCA lists MBD as one of the more common diseases in pet dragons, most often in juveniles under two years. Signs include a swollen or soft lower jaw, swollen hind legs, trembling legs and lying flat instead of standing up.
  2. A diet out of balance. Too much phosphorus and too little calcium or vitamin D3 feeds into MBD. Our feeding chart by age covers portions and calcium dusting.
  3. Temperatures that are too low. The RSPCA warns that a cold enclosure slows digestion and makes impaction (a gut blockage) more likely, especially with loose substrates like bark, wood chips, walnut shell or corn cob.
  4. Cold, dirty or stressful housing. VCA links respiratory infections, including pneumonia, to dragons kept stressed, poorly fed, or in cold or dirty conditions. The RSPCA stresses good ventilation.
  5. Parasites and infections. Intestinal parasites are common and often mild, but heavy loads cause diarrhea and weight loss. Yellow fungus disease (CANV) and atadenovirus can be serious or fatal, which is why new dragons are worth a vet check.
  6. Egg problems in females. Females can produce eggs without a male. Without a digging box she may become egg-bound, which the RSPCA calls a serious condition.

Our bearded dragon care guide walks through a setup that avoids most of these.

Signs your bearded dragon may be seriously ill

People often search “is my bearded dragon dying” after a few quiet days. Dragons hide illness well, so the honest answer is: you can’t tell at home, but you can tell when it’s time to call a reptile vet. VCA’s guidance is that any change from normal is cause for concern and should be evaluated by a veterinarian. Go promptly if you see:

If your dragon is weak, struggling to breathe or unresponsive, treat it as an emergency.

Old age, brumation or illness?

Usually brumationPossibly illness
TimingCooler months, comes on graduallyAny time, can be sudden
WeightStays roughly stableDrops across weigh-ins
When awakeAlert, normal postureWeak, lying flat, eyes sunken
Other signsNoneBreathing changes, swelling, abnormal droppings

The RSPCA says a brumating dragon shouldn’t lose weight or stop eating entirely. If you’re unsure, our free brumating or sick check and the brumation guide help you sort out what to watch, but they don’t replace a vet exam.

How to help your dragon live longer

  1. Replace UVB bulbs on the maker’s schedule, and keep a proper basking spot with a cooler end.
  2. Feed for the dragon’s age and dust insects with calcium as directed.
  3. Use a safe substrate and keep the enclosure clean and well ventilated.
  4. Weigh in grams on a regular schedule and keep the numbers. A slow drift is easy to miss without a record.
  5. Find a reptile vet before you need one, and bring a fresh dropping for a parasite test after you get a new dragon.

Keep a record you can show a vet

Most of the warning signs above are changes over time, so a dated record of weight, photos and appetite is the most useful thing you can bring to an appointment. A notebook works. We make Beardie Days for keepers who want weight, length, photos and care notes in one timeline per dragon; it’s free for two dragons with five records each, with Premium for unlimited records.

Frequently asked questions

How long do bearded dragons live as pets?

Veterinary and welfare sources put a pet bearded dragon’s lifespan at roughly 7 to 15 years: VCA Animal Hospitals says about 7 to 12 years with proper care, and the RSPCA says usually 10 to 15 years or more. Husbandry, diet, UVB lighting and early veterinary care make most of the difference.

How can I tell if my bearded dragon is dying?

There is no single sign. Lethargy, not eating, weight loss, sunken eyes, weakness or being unable to hold the body up, trouble breathing, or a swollen jaw or limbs all need a reptile vet promptly. VCA advises that any change from normal should be evaluated by a veterinarian.

How do I know if my bearded dragon is old?

Dragons are usually considered adult from around one to two years. Older dragons often eat less, move and bask more slowly, and may lose some muscle. Those changes should be gradual; sudden weight loss or weakness is not simply old age and should be checked by a vet.

Is my bearded dragon brumating or sick?

Brumation is a seasonal slowdown: more sleep and less food, usually in cooler months. The RSPCA notes that a brumating dragon should not lose weight or stop eating entirely. Weigh your dragon regularly, and see a vet if weight drops or if the dragon seems weak rather than just sleepy.
