Why Isn’t My Bearded Dragon Eating

First things first, you must observe the behavior of your pet and know the reason why your bearded dragon is refusing to eat food. There are a number of reasons why a bearded dragon goes long without food.

Off Temperatures

Reptiles are often sensitive to their surrounding temperatures. These cold-blooded lizards want the temperature hotter than a basking lamp. Due to their Australian origin, their body needs higher temperatures to carry out their physiological processes which include digestion. If the enclosure is not set to the optimum temperature and is cooler than usual, then it means your beardie either feels sick or can’t digest the food he has eaten prior.

Off Temperatures

An adult bearded dragon needs a temperature of about 105 degrees Fahrenheit and a baby bearded dragon needs 100-110 degrees Fahrenheit. Therefore, check the readings of the thermometer first, if your beardie is having trouble eating. An adjustment in the heater should fix your issue within days.

Changes In The Enclosure

Remember that you are petting a very sensitive creature. These smart lizards sense changes in their environment very quickly and then change their behavior accordingly. They tend to protect their land and resist any invader that comes near them or their habitat. Therefore, if you add new furniture to its enclosure or cage, or even make some slight changes, it will change its behavior and might refuse to eat the meals you try to feed it.

Changes In The Enclosure

In case you have changed its entire home or shifted your beardie to a new enclosure, your pet might be upset about it and refuse to eat for a few weeks. Dragons feel threatened or not safe in new places and so react differently. It is best not to make changes to the dragon’s home and the behavior usually wears off in a week or two. However, if your pet still goes weeks without eating, then you should take him for a checkup.


As mentioned before, beardies are sensitive creatures. They can be stressed out by the slightest of new changes. In such cases, a caretaker must do anything he can to comfort the pet and calm it down. A beardie can be stressed if it spots another bearded dragon or simply another creature. It can also be stressed if it has constipation or any uncomfortable object near it.


Figure out what is threatening your pet and get rid of it as soon as possible. A stressed dragon can go a week without food at most as stressing out takes a lot of energy and then it might want to eat some food.

Changed Diet

A common cause of not eating food is feeding a new or unfamiliar meal to your lizard. Bearded dragons can be very stubborn when it comes to the selection of food. These notorious reptiles are very picky about their meals and often refuse to eat new foods or foods that do not crave for. Also, read How Often Do Bearded Dragons Eat?

Brumation Period

Your exotic pet might be going into its brumation phase. Bearded dragons go into brumation once a year, and if a year has passed since its last brumation then this might be the very reason your pet hasn’t eaten for a long time.

Brumation Period

Brumation is hibernation for bearded dragons when they prepare themselves for a long sleep or shut down during the cold season. During the brumation period, bearded dragons minimize their movements to almost none at all and stop eating. You will see them surviving on very less water. This lasts about two months.


The last cause of not eating food is sickness. If all of the above reasons are not the case with your pet, then you must immediately head to an animal doctor.
