How to care for your Rankins Dragons (Pogona henrylawsoni)
The Rankins Dragon (also known as the dumpy dragon, Lawson’s dragon, black soil dragon, or dwarf bearded dragon) is native to Queensland in northeast Australia. They are considerably smaller than the closely related bearded dragon, only reaching an average size of 20 to 30 cm including tail.
Care is broadly similar, although they have a reputation for being far more tolerant of cohabitation.
They have an average lifespan in captivity of 7 to 9 years, and are easily bred – although it can be very hard to obtain truly unrelated specimens, as the gene pool is very small.
Rankins dragons are active lizards so should be given a vivarium large enough to meet their needs, which means a minimum size of 900 x 450 x 450mm (36 x 18 x 18″).
A wooden vivarium is recommended as they are better insulated than glass or plastic vivariums, making it much easier to get the heating set up correctly. A wooden vivarium will offer more privacy for the dragon, as they only have a glass front.
Temperature is very important in reptile care as they cannot produce their own body heat and need to be kept within a suitable range to help the body function correctly.
Rankins Dragons require a temperature range of up to 45°C (113°F) in the basking area, down to approximately 30°C (86°F) in the cooler area. This will provide the dragons with a temperature gradient across the vivarium, allowing them to choose the most suitable temperature at all times. At night the temperature should drop to 26°C (78°F) at the warmest part of the vivarium.
These temperatures can be achieved by using basking lights during the day and a ceramic heater at night. A thermostat should always control the ceramic heater. Ideally basking lights, in particular ones with a higher wattage, should be controlled by a separate thermostat.
It is very important to know what the temperature is, so check regularly with an accurate thermometer. Ideally use two maximum/minimum thermometers per vivarium (one at each end of the vivarium), or you can use an in/out, max/min thermometer and place 1 sensor at each end. Do not guess or take temperature by hand (if it feels warm or cold), this is not accurate enough.
Rankins dragons require a good quality UV light to help use calcium from their diet and prevent Metabolic Bone Disease. We recommend using a 10-12% T5 UVb .UV lights should be mounted directly above the dragons, at a maximum of 12 inches above the main area. It is recommended to replace UV lights every 6-12 months (depending on brand of lamp) due to a decline in UV output.
Basking lights in white are vital to both provide the vivarium’s hot spot, but also stimulate the dragon to behave normally.
A simple 12 hour light cycle is ideal for a Rankins dragon.
It is important to provide your dragon with fresh water every day, in a shallow bowl to help the dragon and crickets climb out of the water. Although Rankins dragons are from arid regions of Australia they are prone to dehydration. To prevent this, it is important to spray your dragon with water as this is how they would normally drink in the wild. You can also give a warm water bath once or twice weekly/as required. Don’t spray your dragon more than once a day as this will raise the humidity and can cause respiratory problems.
