Bearded dragons need to be bathed a couple of times per week. Bathwater should be no deeper than its knees, with water that's 85 to 92 degrees Fahrenheit. All you need to do is splash water on the dragon and let it enjoy itself in the water, no soaps are needed! After about 20 minutes, remove it from the bath and pat it dry. Get it back under its warm lights to make sure it stays toasty.
