Bearded dragons are one of the most popular pet reptiles, and with good reason: they are curious, social, and relatively hardy. But many of the health problems we see in reptiles trace back to one thing: the habitat.
A Proper Heat Gradient
Reptiles rely on their environment to regulate body temperature. Your dragon needs a warm basking area on one end of the enclosure and a cooler side on the other, so they can move between them. Use reliable thermometers on both ends rather than guessing.
Why UVB Matters
UVB lighting allows reptiles to make vitamin D3 and absorb calcium. Without it, dragons can develop metabolic bone disease, which causes weak bones, tremors, and deformities. UVB bulbs lose strength over time even when they still look bright, so replace them on the schedule the manufacturer recommends.
Signs Something Is Off
Watch for lethargy, poor appetite, swollen limbs or jaw, twitching, or trouble climbing. These can be early signs of husbandry-related illness.
