Signs Of An Unhealthy Bearded Dragon

Although being a very vigorous creature, bearded dragons also suffer from health issues. An unhealthy bearded dragon, instead of telling us what is the matter, may show signs or symptoms of an unsound condition.

Therefore, as their caregiver, you had better pay great attention to any signs of an unhealthy bearded dragon as these signs could give clues or evidence about any possible illness or a disease that an unhealthy bearded dragon is going through so that you can find a good solution for these issues such changing its habitat or diet, visiting a reptile veterinarian and so on.

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


#1 Lethargic


An unhealthy beardie 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 beardie, 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 beardies 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.

#2 Damaged Snout/Bloody

The common reason for a bloody damaged-looking snout is snout rubbing as a beardie is kept in a too-small enclosure for its size.

Also, they can try to find a way out of the enclosure, which can hurt their snout and make it bloody and raw. You can remedy this by giving the beardie an adequate enclosure, a well-balanced, and varied diet.

You can interact with the beardie by taking him out of the habitat occasionally for entertaining activities. In specific, you can take him for a walk with a special lizard leash or allow the beardie to sit in your lap to explore a safe room for 30 minutes to an hour a couple of times per week.

Snout rubbing may be an indication of stress so you should give him an appropriate hide box, and monitor terrarium temperatures.

#3 Malnourished Appearance/Bony

There are many reasons for a bony, malnourished appearance of an unhealthy bearded dragon. The first reason is that the bearded dragon is not eating correctly due to stress, improper temperatures, a lack of adequate UV lighting, or a sign of a more serious health condition.


You should monitor terrarium temperatures by using a quality reptile thermometer. In addition, you can encourage or stimulate your beardie to eat well by varying its diet as much as possible as well as providing enough food items with calcium powder.

In order for your beardie to get exposed to adequate UV radiation, you can use a Repti Glo 10.0 fluorescent bulb or equivalent products that are suitable for desert-dwelling reptiles.

An unhealthy bearded dragon suffering from stress will have a darkened or black stomach. Regarding beardie that has been brought to a new home or experienced environment changes.

Also, it is the feeder insect left in the habitat overnight or the incorrect temperature that causes your beardie stressed.


When being in a new home, a beardie is more likely to feel unsafe, strange, and scared. Therefore, you had better give it time to get accustomed to the new surroundings by providing it a good hiding place in an attempt to reduce stress as much as possible.

Also, you should avoid annoying your beardie except for regular feedings and cleaning, and gradually increase contact at a slow pace to avoid stressing the beardie.

Monitoring temperatures regularly to make sure that they are not too low or too high. Otherwise, temperatures can cause undue stress for the reptile.

Regarding feeder insects, you do not want your beardie to be crawled on and bitten by them, which makes your pet stressful. Therefore, you had better remove uneaten feeders after 15 – 20 minutes after feeding.

A drop or other impacts can lead to tail, or limb disfigurement among beardies while weak or brittle bones can indicate a sign of Metabolic Bone Disease.

In case the end of the tail becomes black and dead-looking, it must be a bacterial infection called tail rot.


In case of a broken bone, you had better seek a veterinarian immediately for x-rays and diagnosis as a blood test will be performed to check calcium levels.

Before visiting the veterinarian, you should use ice and gently massage the area of the suspected broken bone to help reduce swelling.

Tail rot is extremely dangerous as it causes the section of the tail to turn black and fall off, and it even gradually moves up the tail and enters the body, which leads to death. The only way is to seek a veterinarian for antibiotic treatment as soon as possible.

You can minimize the opportunities of possible tail rot by taking these steps. Firstly, keep husbandry conditions sanitary by having the terrarium cleaned regularly with an anti-microbial cleaner safe for pets such as Healthy Habitat.

Secondly,  leaving feeder insects in the terrarium for long periods of time or at night should be avoided as crickets will chew on the bearded dragon’s tail. Last but not least, provide the BD with a warm bath at least once per week to keep the skin clean and supple.

Preparing a proper diet and avoiding feeding lettuce is recommended as lettuce contains a lot of water instead of nutritional value, which can cause diarrhea and dehydration.

Regarding internal parasites, feeder insects raised in contaminated conditions are the main culprits. Therefore, you had better choose fresh and strong feeders that are nurtured properly and don’t hesitate to search for a trustworthy feeder supplier.

Cleaning and sanitizing your beardie’s habitat regularly plays an important role.
