Many people view reptiles as cold and distant animals that do not really communicate. However, that is far from the truth. You may have heard, or noticed, that:
- Bearded dragons wave their arms;
- They can change color;
- Bearded dragons are hardy and not prone to diseases.
- Beardie gestures are not random; they all have their meanings.
- Beardie’s color change can tell you something about their health, mood, and environment;
- Although bearded dragons are generally hardy, they can fall victim to several common diseases which you should pay attention to.

Bearded Dragon Behavior & Body LanguageJust because bearded dragons are not vocal, that doesn’t mean that they do not communicate. Beardies use body language to interact with members with their own species, as well as other creatures they encounter. Humans do not understand these signals intuitively. We have learned about them through study and observation. It is important for every bearded dragon owner to learn to interpret the gestures of their pets. Common behaviors of bearded dragons include
- Head bobs
- Changing color
- Mouth gaping
- Beard puffing up
- Tail pointing upwards
- Wobbly walking
- Lack of movement
- Moving the front legs only
- Twitching or jerking movements
- Looking upwards for no reason (“stargazing”)
- Soaking too much
Waving: Why Do Bearded Dragons Wave?When you appear in front of your beardie, sometimes he will raise his front foot and literally wave at you. This is a hilarious situation because it looks like he just said “Hi!” to you. Well, that is because he is saying “Hi!”. Sort of. This “greeting” essentially says two things: “I am here,” and “I come in peace, don’t hurt me.” It’s both a signal of presence and submission. That is the reason why insecure young beardies will perform the wave more often than mature adults. Beardies will use waving among the members of their own species, as well as with humans and other animals they encounter.
Head Bobbing: Why Do Bearded Dragons Bob Their Heads Up And Down?Head bobbing is a sign of domination. It occurs when bearded dragons want to establish a social hierarchy among themselves. Faster bobs are meant to serve as a warning and a threat. Slower bobs signal submission. Also, male beardies will do jerky bobs when they are courting a female. Some beardies will bob obsessively when going out of brumation, especially if they can feel the scent of a female. If a male bearded dragon is bobbing his head at you and it is springtime – it’s just his hormones running wild in the face of a breeding season. Sometimes beardies will do short slower bobs that look like nodding to acknowledge each other – or their humans.
Changing Color: Why is my bearded dragon turning dark or white?Why do bearded dragons sometimes turn black? The main reason is temperature regulation. Black surfaces soak in more warmth. That is why you will often see bearded dragons turn black and flatten out in the morning when you turn on the light, or if you take them out for a walk and basking in the natural sunlight. Some beardies will also turn black when they get aggressive. However, in combination with other disease symptoms, the blackened skin can be one of the signs of stress or disease.
Why is my dragon’s beard turning black?The bearded dragon’s trademark beard will become enlarged and dark if he is excited, scared, aggressive and ready to attack an intruder, or ready to mate. In these cases, the black beard is a passing occurrence. However, if the black beard is persistent, it is a sign that your beardie is suffering. He could be in pain, or there might be something wrong with his habitat. Some older bearded dragons will show a constantly black beard before the end of their lives.
Why is my bearded dragon suddenly pale?If your bearded dragon turns pale, that is a sign of an upcoming shedding. You can read more about shedding below. Also, some beardies will get lighter when sleeping!
BaskingBasking under a heat lamp or in full sunshine is a behavior that beardies exhibit daily. That way they collect heat, and UVB radiation which helps create vitamin D3 to metabolize calcium. As said above, many bearded dragons will flatten their bodies and turn darker to soak in as much as warmth and ultraviolet light as possible.
Mouth Open: Why Do Bearded Dragons Open Their Mouth?The most common reason for a beardie to keep his mouth open is controlling his body temperature. Bearded dragons will often open their mouths while basking to prevent overheating. Holding the mouth open is completely normal as long as it happens in short sessions. However, if it goes on for a long while, it could mean that the terrarium is too hot, or that there are some underlying health issues. If coupled with heavy breathing, gaping mouth can signal a respiratory infection.
Licking: Why Do Bearded Dragons Lick?The tongue is one of the bearded dragon’s main tools for exploring the world around him. Like other reptiles, beardies have a Jacobson’s organ, which lies at the roof of their mouth. When they lick something and then retract the tongue, its forked tips pass the smell to the Jacobson organ. That way they use licking for both tasting and smelling.
Yawning: Do Bearded Dragon Yawn?All lizards can yawn from time to time. A bearded dragon’s yawn consists of puffing out the beard a few times (this may look like hiccups) and then opening and closing the mouth. Yawning usually happens in the morning, or upon waking from a nap. And why do bearded dragons yawn? As strange as it sounds, no one is really sure what is the true function of yawning, not just in reptiles, but in any species.
Tail Curl: Why Is My Bearded Dragon Tail Curling?The tail curling gesture in bearded dragons signals alertness. Bearded dragons will curl their tails up when excited, chasing prey or running around for other reasons. They will also exhibit the tail curl as a reaction to warmth – when put in hot surroundings or in warm water.
Brumation: Do Bearded Dragons Hibernate?Brumation is a reptile version of hibernation. It occurs within the same time period – fall and winter, but it is different from hibernation in the sense that reptiles do not shut down their metabolism completely – they just slow it down. Also, they do not really “sleep.” Each bearded dragon will brumate differently and maintain different levels of activity. However, all reptiles need to stay hydrated during brumation. While brumating, your beardie will fall into a slumber that will last for months, during which he might not eat or drink a lot – or not at all. If you get worried, always remember that brumation is a natural process which should not be stopped.
What are the Signs of Bearded Dragon Brumation?The first sign of brumation is a radical change in behavior. That includes:
- Frequent hiding;
- More naps and “sleepy look;”
- Sluggish movement;
- Poor appetite.
Shedding: How Often Do Bearded Dragons Shed?Shedding is a normal process in all other lizards and snakes. Reptiles lose their old skin in one piece, or in chunks – like bearded dragons. One of the reasons for lizard shedding is that they literally outgrow their old skin. That is why juvenile and young bearded dragons that grow fast will shed much more often. Shedding may last three to ten days. During this time, beardie’s look and behavior will change.
Signs of shedding in bearded dragonsSometime before the shedding, you will notice that your beardie’s color will change and become dull. At this time, he will get itchy and uncomfortable, which will cause him to avoid food and possibly sleep a lot. Some beardies do not eat through the entire shedding process, and that is perfectly normal.
How to Help a Bearded Dragon with Shedding?There are ways to help your beardie with his shed:
- Warm soaks and gentle scrubbing with a soft toothbrush;
- Misting your beardie’s body;
- Not bothering him too much in general.
Bearded Dragon Unusual BehaviorUnusual behaviors in bearded dragons are usually signs of distress or sickness. Some of these behaviors are essentially normal – it is normal bearded dragons to dig or defend themselves for instance – but they can signal the need for your intervention and help. Other behaviors – such as constantly gaping mouth – are undoubtedly signs of sickness.
Angry Bearded Dragon: Why Are Beardies Hissing and Biting?Bearded dragons are feisty and energetic lizards which can get “angry” for many reasons. Hissing is a first warning sign. When a bearded dragon feels threatened, hissing is a way to warn the aggressor that he will defend himself. At the time of hissing, his beard will get puffed up and black as well. Hissing will sometimes progress to biting, which is a pretty straightforward presentation of aggression.
Bearded Dragon Aggressive Towards HumansIf you got your dragon as an adult and he hasn’t been properly used to being handled or was mistreated by a human hand, he will see it as a threat and will defend himself the only way he can. Do not risk getting bitten by trying to handle an aggressive dragon without protection. Wear thick gloves and try short daily sessions of handling, along with hand-feeding them some treats in their terrarium during meal time. When your dragon learns that your hand is not a source of discomfort, he will stop with the aggressive behavior.
Bearded Dragon Aggressive to Other Bearded DragonsIf you house several bearded dragons together and they become aggressive towards each other, the only solution might be to separate them. Male beardies are territorial and will certainly fight; two males should never be kept together. Females will often live together peacefully, however, always remember that every beardie is different. If you are planning to keep two or more beardies together, make sure to have a spare tank just in case things turn sour.
Glass Surfing: Why my Bearded Dragon Won’t Stop Scratching at the Glass?Glass surfing usually indicates that your beardie is stressed by something in his environment. New decorations, new tankmates, and an enclosure that is too hot or that has become too small are all reasons that can lead to glass surfing. Trying to climb glass is the beardie’s attempt to escape into a safer environment. On the other hand, beardie who is often taken outside and enjoys it may also climb glass if he wishes to get out of his tank for a walk.
Digging: Why Is My Bearded Dragon Digging the Substrate?Digging is a natural behavior of all bearded dragons which has several purposes. Some beardies will attempt to dig when they are in search of a cooler and a more humid environment. If an adult female is doing a lot of digging during the daytime, it is likely that she is ready to lay eggs. Eggs can form even without the presence of a male. As lacking a proper substrate for laying eggs will cause the female a lot of stress, you should put her in a separate tank with about a foot of sandy substrate in it.
Illnesses and Diseases: the Signs of a Sick Bearded DragonLike any other creature, bearded dragons can get sick. There are several diseases that bearded dragons are especially prone to. Fortunately, most of them are preventable. So, what kind of diseases do bearded dragons carry? Here is the list of the most common ones:
- Viral respiratory infections or pneumonia
- Metabolic bone disease (MBD)
- Mouth rot
- Parasitic infections
Bearded Dragon Respiratory Infection: Symptoms and Treatment
Respiratory Infection CauseRespiratory infections in bearded dragons occur if their environment is too cold, too humid or badly ventilated. Also, stress, bad diet, and overcrowding can also lead to respiratory disease.
Respiratory Infection SymptomsMost signs of respiratory illnesses are related to breathing. They include:
- Difficult and raspy breaths;
- Coughing-like exhalation;
- Mucus around the nose and the mouth;
- Gaping mouth;
- Loss of appetite.
Respiratory Infection TreatmentYou need to deal with the potential cause of a respiratory infection immediately. Check and correct the temperature and humidity. Most respiratory infections demand vet care. Your beardie will probably be prescribed injections or oral doses of antibiotics. Other than sorting out your beardie’s living conditions, do not experiment with home remedies for respiratory infections by yourself.
MBD: Bearded Dragon Metabolic Bone DiseaseMetabolic bone disease is the most common metabolic sickness in captive bearded dragons and other diurnal lizards. It is a debilitating condition that leads to slow and painful death if not caught in time.
Metabolic Bone Disease CauseMBD occurs due to calcium and vitamin D3 imbalance. Bones start to weaken, which then leads to deformities, paralysis, and death. It happens because of improper nutrition and supplementation, or improper UVB lighting.
Metabolic Bone Disease SymptomsThe symptoms of MBD get more drastic as the disease progresses:
- Tremors and twitches of fingers, feet, and legs;
- Hard knots along the spine
- Paralysis of the hind legs
- Stunted growth in young beardies
- Receding lower jaw
- Bone fractures.
Metabolic Bone Disease TreatmentMetabolic Bone Disease can be treated efficiently if you catch it early. Quality nutrition with sufficient calcium, UVB lighting, and proper terrarium temperature have to be ensured both as prevention and treatment.
Bearded Dragon Poop: Healthy Poop, Diarrhea, White Poop, Green Poop
How Does Normal Bearded Dragon Poop Look Like?Normal poop of a bearded dragon will look similar to bird droppings, though it should have a more distinct shape. There are two different parts of lizard’s poop – one is dark, and the other is white or light pink. The white parts are actually urates, not feces – because of the need for water conservation, bearded dragon’s bodies have evolved so they can pass the urine in dry form. If the urates are yellow, that means that your pet might be getting too much protein from insect foods. Insect meals will cause stool that is firmer, darker and dry. Vegetable poop will be more watery, greener and may contain undigested fiber. Sometimes there will be more water around the main part of the poo, and that is perfectly normal as long as the water is clear.
How Often Should a Bearded Dragon Poop?How often you can expect your beardie to poop depends on his metabolism, diet and the temperature. Anything between 1 and 7 times a week is considered normal.
Is Watery or Runny Poop a Cause For Concern?As with other animals, a bearded dragon’s poop is a good indicator of their health. Watery or runny poo can signal a health crisis – usually a parasitic infection. If your beardie’s stool looks unusual, smells particularly foul, or your beardie has to go several times a day, do not hesitate to call a vet and do tests to determine what the underlying cause of the runny poop is.
Bearded Dragon Impaction: Symptoms and Treatment
Causes of impaction in bearded dragonsBowel Impaction happens when an animal swallows indigestible matter that blocks the intestines. Most commonly, the cause is a hard substrate such as sand, or chitin shells of insects that are too hard to digest, such as beetles or mealworms.
Symptoms of Impaction in Bearded dragons
- Lack of bowel movement;
- Inability to pass excrement;
- Swollen, bulging or hard stomach;
- Lack of appetite;
- Other signs related to pain and discomfort (black beard, sluggishness, etc.)
Treatment of Impaction in Bearded DragonsMilder cases of impaction can be solved if you give your beardie a few drops of olive oil, or olive oil mixed with some applesauce, followed by a 20 to 30-minute bath in lukewarm water and a really gentle belly massage. Although this is a home treatment, it is best to do it after consultation with a vet. Serious cases of impaction may have to go through a surgery.
Bearded Dragon Mouth Rot: Symptoms and TreatmentMouth rot is an infection of the mouth, and it can prevent your bearded dragon from eating completely. There are several signs of mouth rot watch out for:
- Puss-like yellowish or white substance in the corners and on the edges of beardie’s, mouth;
- Swelling or abscess-like structure in the mouth;
- Losing teeth;
- Lack of appetite;
Eye Infection, Eye Bulging, Swollen Eyes: The Bearded Dragon Eye ProblemsThere are several forms of eye issues that occur in bearded dragons. Swollen eyes can be a sign of eye infection or injury, a vitamin A overdose, or (rarely) a parasitic infection. An upcoming shedding can also make your beardie’s eyes a bit puffy, so it is important to watch out for other signs to make a proper assessment of what’s going on. Droopy Eyes – when eyelids look loose, like those of a basset hound – can be a sign of kidney issues; it is an indication to see a vet as soon as possible. Closed eyes – if your bearded dragon keeps his eyes closed too much and you are not monitoring the level of UV radiation in your tank, it could be a sign of photo-kerato-conjunctivitis.
Atadenovirus: What is atadenovirus?
The CauseAtadenovirus is a highly contagious viral infection which can be deadly to bearded dragons, especially the young ones.
The Atadenovirus SymptomsOther names for the disease – wasting disease and star-gazing disease give a clue about its presentation. Juveniles affected by atadentovirus are smaller and thinner than the rest of their clutch. As the disease progresses, the neurological symptoms will start to show – the dragon will start looking upwards for no reason, often flipping over in the process. As the disease affects movement more and more, the sick beardie will stop feeding, have difficulty breathing and in the end, die.
Atadenovirus TreatmentThere are no drugs that eliminate atadenovirus. All that can be done is the management of the disease and the prevention of spreading. Affected beardies should be kept by themselves and away from other reptiles. Also, never cycle uneaten food, substrate, and equipment between tanks. When buying a juvenile bearded dragon, always go for the larger, plump individuals. Juveniles under 90 days old usually die within those first three months. Some survivors can live a relatively normal life, but have to be well-cared for – stay warm, always have UVB light and be checked for parasites occasionally.
Bearded Dragon Parasites and MitesAll lizards, including bearded dragons, can fall prey to parasites. There are internal (intestinal) parasites – endoparasites, and external – ectoparasites, found on the skin of reptiles.
Intestinal parasites in Bearded DragonsSome of the most common endoparasites in bearded dragons:
- Weight loss
- Lack of appetite
- Vomiting or regurgitation
- Strange stool or diarrhea (with or without visible parasites).
- Bloody diarrhea
- Pneumonia and respiratory issues.
Ectoparasites in Bearded Dragons – MitesMites are the most common external parasites of reptiles. These little tick cousins suck blood by piercing the skin. They are difficult to kill because the chemicals and the heat that would kill a mite would also kill your pet. Mites like to aggregate in the folds and crevices of lizard’s bodies. That is why armpits, joints, areas around eyes demand special attention when doing inspections or treatment. Signs of Mite Infestation
- Excessive soaking in the water bowl.
- Scratching on the rough surfaces in the tank.
- Tiny, red or black dot-like creatures on the beardie’s body.
- Drowned mites in the water bowl
- Damaged skin and incomplete shedding
Treating Mites in Bearded DragonsSince mites are pretty hardy, there are no absolutely effective treatments that are also totally safe for your beardie. Even those insecticides that are certified to be used topically on pets such as Frontline still carry risks. Consult a reptile vet and do a careful study of all the options available before proceeding. When you decide on the treatment, follow instructions carefully to ensure the safety of the reptile and yourself. If you are a child, never try to apply insecticide treatments yourself – ask adults for help! A treatment that is 100% safe (though not as efficient as insecticides) is a warm bath with a small addition of Betadine (Povidone-iodine). Betadine is a topical antiseptic safe to use on snakes and lizards. However, you should never submerge lizard’s head in the solution as it may poison him.
Disinfecting the TankYou will also have to disinfect the enclosure because mites lay eggs and hide in the corners and other inaccessible pockets of the tank. All disinfection methods should be done without your beardie present inside. Options for sterilizing are many. One of the chemical-free methods of disinfecting glass tanks is to seal the tank and leave it in the full sun when outside temperatures are high – 29-32º C (mid-80s-90s F). The temperature in the tank should exceed 55º C (131º F) and remain like that for several hours to destroy all mites. If it’s not that hot where you live at the moment, you can use some of the many chemical methods. No-pest strips and flea collars are perhaps the simplest to use. Make sure your beardie is in a spare tank while you treat the primary one. Some sources claim that lizards can remain in the tank if they are not in direct contact with the strip, but I would avoid the unnecessary risk of poisoning whenever possible. All substrate should be removed and disposed of. If you are using rock slate, you can bake it to kill the mites.
Parasite preventionMaintaining excellent hygiene in your tank is the first step in parasite prevention. Also, it is useful to take your beardie to vet check-ups and de-worming treatments regularly. If you just got a new dragon, never introduce him to other dragons until you are 100% sure he is healthy and parasite-free. Quarantine for reptiles can last for several months. Also, never cycle food, tools, and decorations between tanks.
Seizure: Bearded Dragon TwitchingSeizures in reptiles are the signal that something is wrong with their nervous system. Seizures can occur for several reasons:
- Infections that affect the nervous system;
- Injury to the head or the spine;
- In-born defects.
Dehydration: How Do You Know If a Bearded Dragon Is Dehydrated?Bearded dragons seldom drink water from a bowl. They get most of their fluids from their food and baths. Dehydration can be both a symptom of an illness and a stand-alone health issue. The signs of dehydration in bearded dragons are:
- Wrinkled skin
- Skin that does not retract when gently pinched, but holds shape.
- Sunken eyes
- Lack of appetite
Old Age and Death: Bearded Dragon Dying SignsWhen bearded dragons approach the age of 10, they may start showing signs of old age and declining health. Some of the signs that your beardie’s life is coming close to an end are:
- Lack of appetite or a failure to eat on their own
- Partial or complete loss of motor ability, lack of movement
