This is my first bearded dragon, I don't know what to look for.

She's shedding, but she also seems very dehydrated. She came with a 50-gal, branches, a hide, and UVB and day and nighttime lamps. She's a year old and seems on the side, maybe about 7 or 8 inches. She acts very lethargic, with short bursts of activity.

I feel like an awful new owner, because I can't even settle her in properly yet-- in the hubhub of the transfer, the screen lid for her tank didn't make it into my car, and without a lid to keep the cats out and the lamps on, I felt helpless-- helpless enough to bring her to work with me. She's cuddled into a shoebox right now, with the lid open if I'm able to keep half an eye on her and closed if a customer approaches. She's got some greens and Zilla fortified bearded dragon kibble in with her, although she doesn't appear to have much of an appetite. I'm freaking out just a little. There's an hour and a half left in my shift and I'm not sure if her former owner will bring the screen lid over in time for me to have her settled in by evening.

A few photos:



Shoebox is a standard size,for reference.




During a lethargic period.

The fellow described her as "docile", but she seems almost too docile for my gut instinct to feel good about her condition...

Please help!
