Why Is My Bearded Dragon Beard Puffing? Top 8 Reasons

The most commonly observed reason why bearded dragons puff out is whenever they feel intimidated or stressed out. However, this is just one of the many reasons. Let us understand each of the reasons in detail. 

  1. Detecting Sense of Threat

In wild habitats, bearded dragons fend themselves off on their own. Their natural way of defending themselves is to puff out their beards. Bearded dragons also have good hearing abilities, not only that but the ability to detect vibrations.

The puffing out makes their spiny projections look prominent and can scare away the threat of other reptiles or animals. This instinctive behavior is imitated even when they are in a domestic environment. 

So whenever they feel threatened by the presence of some other pet or any other bearded dragon in the same terrarium your pet bearded dragon may puff out. While puffing up under threat their beards may also turn dark or blackish in color.  

  1. Experiencing Stress

Stress is another major reason why bearded dragons may puff up. 

If your bearded dragon is recently brought to your home, it will take some time to adjust to the new environment. The new bearded dragon may be under stress due to this. At such times you may often notice it is puffing out its chin. The darkening of the chin can also confirm that it is under stress.

Relocation and an unhealthy diet could also induce stress in your pet bearded dragon. When your pet bearded dragon is new, there is also a chance that it perceives you as a threat. This could add to the stress of your bearded dragon and make it puff up often. 

  1. Guarding Their Territory

Bearded dragons are territorial in nature. If two or more bearded dragons are housed in the same pet enclosure, territorial fights may erupt. In order to dominate the other or look more frightening and larger for the other, each bearded dragon may puff up. 

Puffing up in this case is an indication of aggression and a defense mechanism to protect their territories.

  1. Shedding

Shedding is a natural and regular process for bearded dragons. Your bearded dragon will know when their shedding is due.  

In order to make the process easy and faster, they will puff up their necks to loosen up the skin around their neck and bodies a little. This helps them with the shedding process. 

  1. Bathing 

Your bearded dragon may also puff up during its bath time. While giving a bath to your bearded dragon, if the bath dish is too deep and full of water, your pet may puff up. 

This is because it will perceive the deep water as an indication of drowning and will puff itself up to keep itself afloat. 

  1. Playtime

Surprisingly the puffing up of your bearded dragon could also mean that your pet is happy and in a playful mood. 

This behavior can be observed especially while your pet is having a good time with your other pets or simply because it is content and at peace. 

  1. Before Meals

During meals, your bearded dragon can puff itself up probably to make more space in its stomach. The puffing up is also observed if you offer your bearded dragon live insects. 

In a wild habitat, bearded dragons hunt down their food and in order to intimidate their prey they puff up. This behavior is instinctively followed by pet bearded dragons as they perceive live insects as a hunting mission. 

  1. Signaling to Mate

Bearded dragons can also puff up to look more attractive to the opposite gender and signal them for mating. 

Male bearded dragons commonly puff up more than female bearded dragons. The puffing up is usually followed by some light bobbing of their heads, and slight twitching of their tails. 

Should You Be Worried about the Puffing up of Your Bearded Dragon?

Puffing up is a normal behavior for bearded dragons. You can tell the reason behind the puffing-up by observing your pets’ environment and overall behavior.

How to Remove Any Factors That Can Cause Stress to Your Bearded Dragon?

Stress is the most common reason for domesticated bearded dragons to puff up. 

If the stress is caused by the pet enclosure environment, you may want to consider making some changes to it.

  • Other pets like cats and dogs can also increase stress as they may seem threatening to your bearded dragon. Cats especially tend to attack bearded dragons. If other pets seem to be the cause of stress for your bearded dragon, it is best to maintain a safe distance between other pets and your bearded dragon.
  • An illness or some infection, either bacterial or fungal, could also increase the overall stress of your bearded dragon. If your pet shows any physical symptoms of disease or illness along with frequent puffing-up, it is best to consult a veterinarian doctor.  
  • If your bearded dragon is newly brought and is stressed around you, giving it some time to adjust itself and get acquainted with you gradually will help ease the stress your pet is facing. 
  • Lastly, providing your bearded dragon with a good habitable big enclosure, along with a nutritious, healthy, gut-loaded diet, will avoid the occurrences of infections and diseases in your pet, thereby preventing any illness-induced stress.
