Bearded Dragon Signs of Aggression
Bearded dragons are generally not aggressive by nature (which is what makes them such good pets). Generally the worst thing you will see is they will show signs of aggressive behavior, and if you provoke them enough they may try and bite you.
Below are some of the most common signs of aggression in both male and female bearded dragons:
Fluffing Their Beard / Bearding – This where the bearded dragon got its name. A bearded dragon will fluff its beard as a threat sign. Obviously it makes the dragon seem bigger and more threatening so it can be seen as a sign of aggression. Sometimes a bearded dragon’s beard may turn to a darker or even black color when they are bearding.
Hissing – Bearded dragons may also hiss if they feel threatened. Again this is another sign of being uncomfortable or a sign of aggression.
Biting - It is fairly obvious that biting is a sign of aggression. If your bearded dragon tries to bite you when you handle it, you should simply put on a pair of gardening gloves because not handling your bearded dragon will not lower their aggressiveness…it will only prevent you from developing a closer bond with your beardie.
Head Bobbing - Bearded dragons will bob their head up and down as a sign of territorial aggression towards one another. Occasionally, they will bob their heads at each other as a sign of communication. For example, one bearded dragon may bob his/her head four or five times fairly quickly, and another bearded dragon may bob his/her head twice more slowly in response as acknowledgement.
