Have Reptile Veterinary Questions? Ask a Reptile Expert.
Hi this is Dr. Hill. Bearded dragons can go through a period of brumation (hibernation in reptiles). This is not always necessary unless she is a breeding female. I need to ask a few questions.
What is the temperature range in her cage?
Please describe the set up for heating and light sources.
What is her diet?
Do you have any other reptiles?
How long has she been exhibiting this behavior?
So her cage should range from 80-95 degrees degrees during the day and not go below 70 at night. She should have a Basking site that goes up to 100. You need to measure the temps with a thermometer on the basking site and not just the air temperature in the cage. Based on the temperatures you gave, she is likely too cold. This may play a factor in her lethargy. What is your light source? Do you have a heated basking spot? What is your weather like right now. She would benefit from 30-60 minutes of unfiltered sunlight, if it is not too cold outside where you are located. I suspect there are some husbandry issues that can be corrected and she will likely perk up. You need to weigh her every few days to keep and eye on her weight. If she is not improving after adjusting her environmental temperatures, then she needs to be seen by an exotics veterinarian.
