Sorry Power Outage.
I need to correct some of the husbandry for you and will tell you how to treat the Dragon.
The sand can cause some major issues with a Dragon. This will give you an idea about Sand as a substrate: http://www.beardeddragon.org/articles/impaction/?page=3
I suggest using a solid substrate like tile, cage carpet, slate or paper. Sand can also cause skin problems and corneal ulcers in the eyes. The basking area should have 105*-110*F, the warm side 90's and the cool side of the tank in the 85* range. This is important for digestion and passing of stool. If the temps are not correct, this can also cause a problem.You should be feeding Collard greens, mustard greens, dandelion greens, escarole and curly endives. Butternut squash and various berries are great for a treat. The Veggies should be put in fresh daily, and done about an hour after lights on. Lettuce is worthless as it holds no nutritional value. They need 20% veggies daily and 80% live prey under a year of age and over a year the percentages reverse. The live prey should include crickets, silk worms, roaches, goliath worms and phoenix worms. Meal worms and super worm high in chitin which is the outer shells and can cause a blockage.
Super worms and wax worms are like giving the Dragon candy. All veggies and prey should be dusted with calcium daily 5 days a week and vitamins 2 days a week. This is a link to the Veggies and is color coated. Please follow the green foods:
Now to help the Dragon, we need to feed a little Baby food prunes and wait about 45 mins and place the Dragon in a Soak and massage the abdomen. This should promote a stool. If it does not can be repeated daily for two days. If it does not work, the a Herp Vet will be needed to check for a blockage and possibly an enema or other measures to promote a bowel movement.
