# Bearded Dragon Care in the UK

UK bearded dragons need a **thermogradient vivarium**, a basking spot of **38–42°C**, a quality **UVB tube replaced on schedule**, and low-to-moderate humidity (~30–40%). Incorrect lighting and temperature are the leading causes of illness — register with an exotic vet before problems arise.

## Vivarium setup

According to the RSPCA and PDSA, bearded dragons (*Pogona vitticeps*) are active diurnal lizards needing generous space:

- **Minimum size** — adults need at least 120 cm long vivarium; larger is better for thermoregulation and enrichment
- **Substrate** — reptile carpet, tiles or paper for beginners; loose substrates risk impaction in juveniles
- **Hides** — one on the warm side, one on the cool side
- **Branches and rocks** — sturdy basking platform under the heat and UVB zone

Never use **heat rocks** — they cause severe burns. All heat must come from overhead ceramic or basking bulbs on thermostats.

## Basking and cool zones

Bearded dragons must move between warm and cool areas to regulate body temperature:

| Zone | Target temperature |
|------|-------------------|
| Basking surface | 38–42°C |
| Warm end ambient | 32–35°C |
| Cool end | 22–26°C |
| Night drop | Can fall to 18–21°C — turn off basking; some keep low background heat in winter rooms |

Measure with **digital thermometers** at basking surface and cool end — dial gauges on glass are unreliable.

Use a **dimming thermostat** on the basking bulb to prevent overheating. Ceramic emitters provide night warmth without light if room temperature drops too low.

## UVB lighting

According to RSPCA reptile guidance, bearded dragons are **UVB-dependent** — without it they develop metabolic bone disease (MBD):

- **Tube UVB** — use a reptile-specific T5 or T8 tube spanning much of the vivarium length
- **Distance** — follow manufacturer chart (typically 25–40 cm from basking spot)
- **Replacement** — every **6–12 months** even if still glowing; UV output fades silently
- **No obstruction** — mesh blocks UV; glass filters it completely

Combine UVB with **calcium and vitamin D3 supplementation** on insects per vet advice — UVB alone does not replace dietary calcium.

## Humidity and shedding

Bearded dragons come from arid Australian habitats. UK homes vary — aim for **30–40% ambient humidity**:

- Provide a shallow **water dish** — many dragons ignore it but some drink
- **Misting** lightly once or twice weekly can aid shedding; avoid soaking the whole tank
- **Shedding problems** — retained toes or tail tips suggest low humidity, dehydration or illness

A separate **bath in lukewarm water** 10–15 minutes during difficult sheds is acceptable if supervised — never leave unattended.

High humidity with poor ventilation causes **respiratory infection** — ensure adequate airflow without draughts on the basking dragon.

## Diet by age

According to the PDSA:

### Juveniles (0–12 months)

- **80% live insects** — locusts, crickets, dubia roaches sized appropriately
- **20% leafy greens** — spring greens, dandelion, squash
- Feed **2–3 times daily**; dust insects with calcium most feeds and multivitamin weekly

### Adults (12+ months)

- **80% vegetables and greens** — kale, pepper, squash, occasional fruit
- **20% insects** — 2–3 insect feeds per week
- **Daily salad**; avoid spinach and iceberg lettuce as staples

Never feed **avocado, rhubarb, fireflies or glowing insects** — toxic. Avoid mealworms as a staple for juveniles (hard chitin, impaction risk).

## Handling and behaviour

Bearded dragons often tolerate handling when warmed and supported fully. Limit sessions to 15–20 minutes. Support the body and tail; never grab by the tail.

**Brumation** — reduced activity and appetite in winter is normal in adults. Confirm with your vet that weight and health are adequate before assuming brumation.

## Health warning signs

Contact an **exotic vet** promptly if you notice:

- Swollen limbs or soft jaw (MBD)
- Not eating for more than 3–5 days (outside brumation)
- Diarrhoea, weight loss or sunken eyes
- Open-mouth breathing, wheezing or nasal discharge
- Paralysis or seizures

Most UK bearded dragon illness traces to **incorrect UVB, temperatures or diet** — review husbandry while booking the vet appointment.

## FAQs

### What basking temperature does a bearded dragon need?

The basking spot should reach 38–42°C, measured with a digital thermometer at the basking surface — not the tank wall. The cool end should be around 22–26°C so your dragon can thermoregulate.

### How often should I replace UVB bulbs?

Replace UVB tubes every 6–12 months depending on manufacturer guidance — output declines before the tube stops glowing. Position within the recommended distance with no mesh blocking UV if possible.

### What humidity is correct for bearded dragons?

Adults thrive at roughly 30–40% ambient humidity. Too damp causes respiratory and skin problems; too dry affects shedding. A shallow water dish and occasional misting help hydration without soaking the vivarium.

### What do bearded dragons eat in the UK?

Juveniles need mostly live insects (locusts, crickets, roaches) dusted with calcium; adults shift to mostly leafy greens with insects several times weekly. Never feed fireflies, avocado or wild-caught insects.
