Signs Of An Unhealthy Bearded Dragon

Below are signs of an unhealthy bearded dragon as well as some recommendations that you should know.


#1 Lethargic


An unhealthy bearded dragon may look quite sluggish or lethargic due to several common reasons such as a deficient diet, uncomfortable environment, or internal parasites.

Also, low environment temperatures can be considered as a common cause as this can result in loss of appetite. Regarding a young bearded dragon, a basking area temperature of between 95°F to 110°F with a cooler region of around 80°F to 90°F is recommended.

One circumstance you don’t need to worry about is that many bearded dragons may bromate or hibernate when the season changes from summer into fall and then into winter.

This will reduce the bearded dragon’s appetite as well as it’s activity levels. Therefore, you had better keep offering food and water as well as maintaining proper temperatures and light cycles.


To monitor temperatures within the terrarium, a high-quality thermometer like a Zoo Med Thermometer/Hygrometer Dual Gauge is highly recommended.

You had better use two measuring tools- one put in the basking area and the other located in the cooler area in order that you can check and control the complete temperature gradient in the habitat.

If you need to modify temperatures, you can have a larger or smaller wattage basking bulb added while a mercury vapor bulb is quite ideal as it can provide both radiant heat and UV radiation.

If there is nothing wrong with the temperature or your dragon is not in the period of brumation time, and he is still acting lethargic, it’s time for you to consult a reptile veterinarian.
