Although Bearded dragons are naturally dry desert animals, there are a few cases where it might be beneficial to actually dip them in a shallow tub of water. Three of the most common scenarios include to aid in the Bearded dragon shedding process, constipation and for rehydration.
The Bearded dragon shedding process are most of the time incomplete (meaning that they shed piece by piece), and problems rarely occurs. In the case of a so-called hard shed one can give daily lukewarm baths until all the skin is removed. The water will penetrate the dead skin layer and help to soften and remove skin in difficult places.
A daily swim in lukewarm water will also help to stimulate muscle contraction and the expulsion of stubborn faeces. This process will also rehydrate a Bearded dragon up to a point where the stool gets softer and easy to be expelled.
Daily baths can also be used solely as a rehydration method for example in a recently sick or anorexic Bearded dragon.
When bathing a Bearded dragon, always make sure that the water level is just deep enough for the dragon to stand in when the legs are stretched out. Lukewarm water works the best. When you feel the water temperature you must actually feel no cold or heat sensation. Daily baths should not take longer than thirty minutes and should always be under full observation to prevent drowning.
