How do I take care of a bearded dragon?

At a glance

What you're signing up for

Start with the honest lifespan. Hobbyist sites like to say 15 years. Veterinary sources do not: VCA Animal Hospitals says 7-12 years with proper care, UC Davis says 7-10, PetMD says 8-10. Plan for 7-12 years, most commonly 8-10 — most of a decade of daily care for an animal that grows to 18-22 inches from nose to tail tip.

The daily reality is kitchen work plus equipment checks. You will chop fresh greens, feed and gut-load live insects, spot-clean, and check temperatures every day. No vet source publishes a per-minute figure; our own estimate from those task lists is roughly 20-40 minutes a day, more on deep-clean days. Treat that as an estimate.

The thing buyers most often don't realize until it's too late: the lighting is not decoration. Without proper UV-B light, bearded dragons cannot absorb calcium, and their bones soften and break. Washington State University's veterinary hospital calls the resulting disease — metabolic bone disease — one of the most common and preventable diseases in pet bearded dragons. Nearly everything that goes wrong with these lizards is husbandry, which means nearly everything is on you.

Housing

The 40-gallon "starter kit" on the pet-store shelf is below every current welfare standard. PetMD still prints "40 gallons or larger" for adults, and that is the size most kits sell. UC Davis says at least 48 inches long, 24 wide, and 18 high — roughly 75-120 gallons. Modern welfare standards go further: ReptiFiles sets 6' x 2' x 2' as its minimum, calling 4' x 2' x 2' acceptable only for small adults around 18 inches; the Federation of British Herpetologists (2022) says about 6' x 3' x 3'; the German Society for Herpetology about 5' x 4' x 3'. Our advice: treat 4' x 2' x 2' as your floor and go bigger if you can.

One dragon per enclosure. ReptiFiles recommends against cohabitation under any circumstances.

Heat is a gradient, and the two main sources measure it differently. UC Davis (air temperatures): basking spot 88-95°F, daytime ambient 80-85°F, nights 70-75°F. ReptiFiles (surface temperatures, current hobbyist standard): basking surface 108-113°F, cool-side surface 77-85°F, nights can drop to 55-75°F. Either way you need thermometers at both ends and a way to measure the basking spot itself.

UV-B is the life-or-death item, so here is the detail. UC Davis: a bulb of no less than 5% UVB, within 12 inches of the basking site, on a timer at about 14 hours light and 10 dark. ReptiFiles, using the modern measure, targets a UV Index of 4.0-4.5 in the basking zone from a T5 HO fluorescent tube — for example an Arcadia 12% or 14% at 11-18 inches depending on mesh — plus bright daylight lighting around 6500K. The trap: UVB output fades while the visible light keeps shining, so a bulb can look fine and be useless, and UVB does not pass through glass. Replacement schedules differ by bulb type: UC Davis says every 3-6 months (older bulb types); ReptiFiles says quality T5 HO tubes last 12 months. Budget 1-4 bulbs a year.

Substrate: skip loose sand for juveniles. It is a classic cause of impaction — a fatal gut blockage. Solid substrates are the safe default while you learn.

Feeding

Bearded dragons are omnivores — VCA's word — and the ratio flips as they grow. This is the single most-missed fact by new owners. Per PetMD: juveniles eat about 70% insects and 30% plants; adults invert to 20-30% insects and 70-80% vegetables and leafy greens. Feed a juvenile like an adult and it can develop metabolic bone disease; feed an adult like a juvenile and you get a fat, short-lived lizard.

Insect size matters more than it sounds. UC Davis warns that inappropriately sized insects can cause partial paralysis, seizures, gut impaction, and even death. The widely taught rule: no insect bigger than the space between the dragon's eyes.

Supplements are not optional. PetMD's schedule: dust insects with calcium, alternating with-D3 and without-D3 daily, plus a weekly multivitamin. UC Davis puts calcium at three times a week for juveniles and weekly for adults. Pick a schedule from a vet source and keep it — a lapsed dusting schedule is one of the standard roads to metabolic bone disease.

Gut-load the insects — feed them well before they become dinner. Your dragon eats what the cricket ate.

Never feed: insects wider than the space between the eyes; insects caught in your yard (pesticide and parasite risk); loose sand mistaken for something digestible; adult-ratio insect loads to a growing juvenile, or juvenile-ratio loads to an adult.

Health

Metabolic bone disease (MBD). The big one. Washington State University's veterinary teaching hospital calls it one of the most common and preventable diseases in pet bearded dragons. Causes: too little calcium or D3, insufficient UV-B, or a bad calcium-to-phosphorus ratio — without proper UV-B lighting, dragons cannot absorb calcium effectively. Signs: a soft "rubber jaw," tremors, limb deformities, fractures, seizures. Juveniles are most vulnerable. Treatment is calcium and D3 from a vet plus corrected lighting; severe cases are hospitalized. Every case traces back to the enclosure.

Parasites. VCA notes that many bearded dragons, even captive-bred ones, carry pinworms — hence its advice: vet exam within 48 hours of purchase, with a fecal parasite check. Most beginners skip this visit. Don't.

Impaction. Gut blockage from loose substrate or oversized prey. Watch for straining with no stool.

Mouth rot (stomatitis). VCA describes cottage-cheese-like material in the mouth and reddened gums.

Salmonella — a people problem. A 2024 CDC outbreak traced to pet bearded dragons: 15 cases across 9 states, 4 hospitalized, 60% of patients children under 5. Dragons can carry Salmonella in their droppings even when they look healthy and clean. CDC rules: children under 5 should not touch reptiles at all; everyone washes hands after handling; keep the enclosure out of infant play areas; never bathe the dragon or wash its dishes in the kitchen sink.

Go to a vet today if: the jaw feels rubbery, or there are tremors or an inability to walk; any seizure; straining with no stool; discharge or cheese-like material in the mouth; a lethargic dragon that won't eat while its enclosure temperatures are correct — at proper temperatures that pattern means sick, not brumating.

A note on brumation, because it panics new owners every winter. Brumation is a normal, hibernation-like dormancy, triggered in the wild by the Australian winter. VCA's picture of normal brumation: lethargy, refusing food, not defecating, darker color — though unlike true hibernators they may still drink. VCA's key test: if your household is at a normal 60-70°F, your pet may not be brumating — it may be sick. Lethargy and appetite loss in a correctly heated enclosure is a vet visit, not a nap. VCA advises only experienced keepers deliberately induce brumation, and only after a health and parasite check.

What it really costs

The dragon is the cheapest part: $30-$100 at a pet store (Reptile Direct says $30-$100, The Vet Desk $60-$100), with color morphs around $500 and rare animals up to $1,000.

Setup is where the real money goes. Reptile Direct puts a proper upfront setup at $300-$700 — a basic tank at $75-$150, a quality vivarium at $300 or more, a screen lid around $30, plus lighting. The Vet Desk quotes $50-$500, but the low end assumes secondhand gear. This is the classic $60 animal, several-hundred-dollar setup problem, and skimping on the lighting half is how dragons get MBD.

Ongoing: food alone runs $40-$120 a month per Reptile Direct if you buy live insects retail; The Vet Desk notes bulk crickets or dubia roaches can cost as little as about $1-$2.40 per feeding unit per month, so bulk-buying changes the math a lot. UVB bulbs run around $20 each, premium ones upwards of $50, at 1-4 bulbs a year. Exotic vet care: an initial visit at $75-$150, routine annual costs of $60-$100 for a healthy lizard, a checkup with fecal test running $80-$200 in the wider exotic-vet market — and The Vet Desk's honest range for annual vet spending is $0-$1,000 depending on illness. All told, expect $400-$1,500+ a year in ongoing costs.

Find an exotics vet before you need one; most dog-and-cat clinics don't see reptiles.

Daily and weekly routine

Daily - Check basking and cool-end temperatures - Fresh water; chop and offer fresh greens - Feed insects per age ratio, dusted per your schedule - Spot-clean droppings - Confirm lights are on their 14-hour-on / 10-hour-off timer cycle

Weekly - Feed the multivitamin dusting (per PetMD's schedule) - Wash food and water dishes — never in the kitchen sink - Check body condition, skin, eyes, and vent - Restock and gut-load feeder insects

Monthly - Deep-clean the enclosure and decor - Check the UVB bulb's age against its replacement schedule (3-6 months or 12 months by type) and log it - Weigh the dragon or photograph body condition to catch slow changes

Common mistakes

1. Buying the 40-gallon kit as forever housing. It is below UC Davis's minimum and every welfare standard. Start at 4' x 2' x 2'.
2. Trusting an old or badly placed UVB bulb. Output fades while the light still shines, and UVB doesn't pass through glass. Replace on schedule; mount at the right distance.
3. Feeding the wrong ratio for the age. Juveniles roughly 70/30 insects to plants; adults flip to 20-30% insects. Get the flip wrong and you get MBD or obesity.
4. No calcium schedule. Pick UC Davis's or PetMD's schedule and follow it like medication.
5. Loose sand plus oversized insects for a juvenile. That combination is the classic impaction case.
6. Misreading brumation. Don't panic at normal winter dormancy — and don't assume a sick lizard in a correctly heated tank is "just brumating." Temperature is the tell.
7. Skipping the new-pet vet visit. VCA says exam plus fecal within 48 hours of purchase. Many dragons come with pinworms.
8. Letting toddlers handle the dragon, or washing it in the kitchen sink. CDC Salmonella rules exist because of real outbreaks.

Is this pet right for you?

A good fit if... - You want a calm, handleable reptile that is active in daylight - You can spend several hundred dollars on the enclosure before the animal - You will maintain lighting and supplement schedules for 7-12 years - You are fine keeping and feeding live insects - Everyone in the house who touches the lizard is over 5 and will wash their hands

Think twice if... - The budget only covers the 40-gallon kit - You have children under 5 or crawling infants at home - You want a pet that doesn't need equipment checked daily - Nobody wants a bin of live crickets or roaches in the house - You can't get to an exotics vet

Worth knowing

They have a third eye. A light-sensing parietal eye sits on top of the skull and detects shadows passing overhead — useful when your predators attack from the sky.

Heat can flip their sex. At high incubation temperatures, chromosomally male embryos develop as functional females. This sex reversal has been documented in wild Australian dragons.

They may dream. A 2016 study in Science found bearded dragons show REM-like and slow-wave sleep cycles — patterns once thought limited to mammals and birds.

They are, very mildly, venomous. A 2005 Nature study found primitive venom glands in bearded dragons — harmless to humans, but a clue to where snake venom came from.

A real Salmonella outbreak was traced to them. The CDC's 2024 outbreak linked to pet bearded dragons hospitalized 4 people; 60% of patients were under 5. The handwashing rules are not fussiness.

The UVB rulebook changed. Modern targets are measured in UV Index — 4.0-4.5 at the basking spot per ReptiFiles — not just "buy a 5% bulb."

Arm-waving is believed to be communication. The slow circular wave is commonly described as an appeasement or submission signal between dragons.

UK welfare standards now start at six feet. The Federation of British Herpetologists set a roughly 6' x 3' x 3' standard in 2022. The 40-gallon kit looks small because it is.

Legal note: bearded dragons are non-native and legal to keep in all 50 states, including Georgia, whose native-wildlife pet ban does not cover them. They are Australian, and Australia banned export decades ago, so US pets are captive-bred.

What you'll need

• 4' x 2' x 2' (approx. 120-gallon) reptile enclosure — adult welfare minimum; bigger preferred
• secure screen lid or vented top — ventilation and escape prevention
• T5 HO UVB fluorescent tube and fixture — without UVB the dragon cannot absorb calcium
• spare UVB tube — output fades before the visible light does; replace on schedule
• basking heat lamp and fixture — creates the 88-113°F basking zone (air vs surface targets)
• bright 6500K daylight lamp — daytime light quality alongside UVB
• light timer — holds the 14-hour-on / 10-hour-off cycle
• two thermometers plus a way to read basking-spot temperature — a gradient needs measuring at both ends
• basking platform and climbing branches — basking access and enrichment
• hides (warm and cool side) — security reduces stress
• solid substrate for juveniles — loose sand is an impaction risk
• shallow food and water dishes — daily greens and water
• calcium powder with D3 and without D3 — alternated dusting per vet schedule
• reptile multivitamin powder — weekly dusting
• feeding tongs — safe insect offering
• live feeder insects (crickets or dubia roaches) — buy from a specialist feeder-insect supplier or local breeder — fresher, cheaper in bulk (buy this where you already shop — we don't sell it, on purpose)
• gut-load food for feeder insects — grocery vegetables and grain do the job (buy this where you already shop — we don't sell it, on purpose)
• fresh leafy greens and vegetables — buy at the supermarket, not a pet store (buy this where you already shop — we don't sell it, on purpose)
