Can you wash a bearded dragon with soap?

Yes you can but only if you must. I prefer a dragon be soaked in just warm water but sometimes if you "Rescue" Like me they come extremely dirty. I use either a bit of dove baby soap, or blue dawn and I dont put it directly on the dragon, just his/hers bath water and run it to make bubble bath and scrub them in that with a tooth brush. but I only had to do this for one rescue who came to me covered in his own feces. I did it to get him clean and examine a missing limb on the animal
