Bearded Dragon Care Guide: Complete Beginner's Manual

Bearded dragons are often called the "dogs of the reptile world" for good reason. They're friendly, interactive, and relatively easy to care for. But like any pet, they have specific needs that must be met for a healthy, happy life.

Here's your complete guide to bearded dragon care.

Why Bearded Dragons Make Great Pets

Temperament

Gentle and curious: Bearded dragons are known for their calm, friendly disposition. They tolerate (and often seem to enjoy) handling.

Interactive: Unlike many reptiles, beardies recognize their owners and may come to the front of their enclosure when you approach.

Diurnal: They're active during the day (unlike many reptiles), so you can actually watch and interact with them.

Varied behaviors: Head bobbing, arm waving, "glass surfing" - they're entertaining to observe.

Enclosure Setup

Size Requirements

Minimum adult enclosure: 4ft x 2ft x 2ft (120 gallons)

Babies: Can start in 40-gallon tanks but will outgrow quickly

Bigger is always better: Bearded dragons are active and benefit from space

Enclosure Types

• Glass terrariums: Most common, good visibility, can struggle with heat retention
• PVC enclosures: Better heat retention, lighter, often preferred
• Wood enclosures: Excellent heat retention but requires sealing

Lighting (Critical!)

Bearded dragons require BOTH:

1. UVB lighting

• Essential for calcium metabolism and preventing Metabolic Bone Disease
• Use a linear fluorescent tube (T5 or T8)
• 10-12% UVB output
• Replace every 6-12 months (even if still glowing)
• Position 10-12 inches from basking spot

2. Heat/basking light

• Provides a hot basking zone
• Use a basking bulb or halogen flood light
• No colored bulbs (they can damage eyes)

Temperature Gradient

Bearded dragons need a temperature gradient to thermoregulate:

Thermometer placement: Get digital thermometers for both warm and cool sides, plus a temp gun for the basking spot.

Substrate

Safe options:

• Tile (easy to clean, natural nail filing)
• Paper towels (cheapest, easy cleaning)
• Reptile carpet (wash regularly)
• Topsoil/play sand mix (50/50, for adults only)

Avoid:

• Loose sand alone (impaction risk, especially for babies)
• Calcium sand (causes impaction)
• Walnut shells (dangerous if ingested)
• Wood chips/bark

Decor and Enrichment

• Basking platform: Flat rock or branch under heat lamp
• Hiding spots: At least one on the cool side
• Climbing branches: Beardies love to climb
• Hammock: Many beardies enjoy lounging in hammocks

Diet

Age-Based Feeding

Protein Sources

Staple feeders:

• Dubia roaches (best option - nutritious, easy to keep)
• Black soldier fly larvae (excellent calcium ratio)
• Crickets (common but noisy, can bite)

Occasional treats:

• Hornworms (high moisture, good for hydration)
• Silkworms
• Phoenix worms

Avoid:

• Fireflies (toxic - can kill your dragon)
• Wild-caught insects (pesticides)
• Mealworms (hard to digest, occasional treat only for adults)

Vegetables (Offer Daily)

Staples:

• Collard greens
• Mustard greens
• Turnip greens
• Butternut squash
• Bell pepper
• Acorn squash

Occasional:

• Kale (high oxalates - limit)
• Carrots (high vitamin A - limit)
• Zucchini

Avoid:

• Iceberg lettuce (no nutritional value)
• Spinach (blocks calcium absorption)
• Avocado (toxic)
• Citrus fruits

Supplements

Calcium without D3: Dust feeder insects at every feeding (for babies) or every other feeding (adults)

Calcium with D3: Once or twice weekly

Multivitamin: Once or twice weekly (on days you don't give D3)

Hydration

• Beardies get most water from food
• Mist vegetables or offer water in shallow dish
• Some beardies drink from moving water (drippers)
• Occasional baths (warm, shallow water) help with hydration and shedding

Handling

When to Start

Wait 1-2 weeks after bringing your dragon home before handling. Let them acclimate first.

How to Handle

1. Approach slowly from the side (not above - predators come from above)
2. Slide fingers under the belly from the front
3. Support the whole body and tail
4. Keep handling sessions short at first (5-10 minutes)
5. Gradually increase duration as trust builds

Signs of Stress

• Black beard
• Gaping mouth (if not basking)
• Puffed up body
• Flattening against the ground
• Running or scratching to escape

If you see these signs, return your dragon to their enclosure.

Health and Common Issues

Signs of a Healthy Beardie

• Clear, alert eyes
• Active and curious when awake
• Good appetite
• Regular bowel movements
• Clean vent area
• Full, plump tail (sign of good fat stores)

Common Health Problems

Metabolic Bone Disease (MBD)

• Cause: Inadequate UVB and/or calcium
• Signs: Weak, rubbery limbs, swollen jaw, tremors
• Prevention: Proper UVB lighting, calcium supplementation

Impaction

• Cause: Ingesting substrate, dehydration, improper temperatures
• Signs: Not pooping, lethargy, bloated belly
• Prevention: Safe substrate, proper heat, hydration

Respiratory Infections

• Cause: Low temperatures, high humidity, stress
• Signs: Gaping, mucus around nose/mouth, wheezing
• Treatment: Requires veterinary care

Parasites

• Common in new dragons
• Annual fecal tests recommended
• Treatment: Prescription medication

Atadenovirus (ADV)

• Contagious viral disease
• No cure, but many live normal lives with management
• Test before introducing to other dragons

When to See a Vet

• Not eating for 2+ weeks
• Significant weight loss
• Difficulty walking or moving
• Visible injuries
• Respiratory symptoms
• Prolapse
• Severe lethargy

Find an exotic vet (reptile specialist) BEFORE you need one. The Association of Reptilian and Amphibian Veterinarians (ARAV) can help you locate a qualified reptile vet in your area.

Daily, Weekly, and Monthly Care

Daily

• Check temperatures
• Offer fresh vegetables
• Feed insects (frequency varies by age)
• Spot clean waste
• Ensure water is available
• Observe behavior and health

Weekly

• Thorough enclosure cleaning
• Replace substrate (if using paper towels)
• Offer a bath
• Deep clean water dish

Monthly

• Clean all decor thoroughly
• Check all equipment (bulbs, thermostats)
• Weigh your dragon (track in a log)

Every 6-12 Months

• Replace UVB bulb (even if still lit)
• Vet checkup recommended

Brumation

Brumation is the reptile equivalent of hibernation. Many bearded dragons brumate in winter.

Signs of Brumation

• Sleeping more
• Eating less or refusing food
• Hiding more
• Sluggish behavior

What to Do

• Don't force-feed
• Keep UVB on normal schedule
• Reduce basking temp slightly
• Offer water weekly
• Let them sleep

Important: If your dragon is under 1 year old, sick, or hasn't had a recent fecal test, consult a vet before assuming brumation.

Common Mistakes to Avoid

1. Cohabitation: Never house two bearded dragons together (they fight, even if they "seem fine")
2. Wrong UVB: Coil UVB bulbs are inadequate - use linear tubes
3. Red/colored lights: These can damage eyes and disrupt sleep
4. Loose substrate for babies: High impaction risk
5. Inadequate basking temps: Too cool = poor digestion
6. Feeding wrong insects: Mealworms as staple, fireflies (toxic!), or wild insects
7. No vet checkups: Even "healthy" dragons benefit from annual exams

The Bottom Line

Bearded dragons are wonderful pets when their needs are met:

1. Proper enclosure (4ft+ for adults)
2. Correct lighting (UVB + basking heat)
3. Temperature gradient (100-110°F basking, cooler side available)
4. Balanced diet (insects + vegetables, with supplements)
5. Regular handling (builds trust and enrichment)
6. Veterinary care (exotic vet for checkups and problems)

With proper care, bearded dragons live 10-15 years. They're friendly, interactive, and make excellent reptile companions.

Frequently Asked Questions

Do bearded dragons need a UVB light, and what happens without one?

UVB lighting is absolutely essential for bearded dragons and is non-negotiable. Without UVB exposure, they cannot synthesize vitamin D3, which is required for calcium absorption. This leads to Metabolic Bone Disease (MBD)—a painful, crippling condition that causes soft bones, deformities, tremors, and eventually death. Replace UVB bulbs every 6 months even if they still produce visible light.

What should I feed my bearded dragon?

Juveniles need a diet of approximately 70% insects (dubia roaches, crickets, black soldier fly larvae) and 30% vegetables. Adults flip to roughly 70% vegetables and 30% insects. Always dust insects with calcium powder and offer a variety of dark leafy greens like collard greens, mustard greens, and butternut squash. Avoid iceberg lettuce, spinach in large amounts, and citrus fruits.

How do I know if my bearded dragon is healthy?

A healthy bearded dragon has bright, alert eyes, a plump tail base (where they store fat), smooth skin without stuck shed, and an active appetite. They should be alert and responsive during the day. Warning signs include lethargy, sunken eyes, black beard that persists (stress), gaping without basking, mucus around the nose or mouth, and irregular or absent bowel movements.
