Well, depending on the size and age, most juvies take about a week or two to go through a complete shed. Their bodes start to dull and white out, then it slowly starts to become more transparent in appearance but darkens the overall look of the dragon. This is when you know it will only be a couple more days before it starts to pop and thats when it begins to get a white color again. Usually within a day, once the skin begins to lift, it will come off completely. Sometimes the tail starts first, then the arms and legs, then the head and body. Dragons can easily get dehydrated during a shed because their bodies use a lot of water to force the skin off, be sure to offer water a couple times a day and don't worry if he refuses to eat as much. Baths will help
hydrate him and sooth the itchy skin, so a daily soak may be helpful. Then make sure he has plenty of stuff to rub against, maybe some rocks or branches with tight spaces to squeeze through, they will seem all crazy the day the skin comes off rubbing against everything and slithering all over the place. When they are done, they seem like they are so proud of themselves and will climb to the highest perch and bask like crazy.
