My bearded dragon's left eye seems to be sunken into its head and the eyelid is half closed. I suspect its dehydration, but I just wanted to make sure. His skin is elastic and his urates ore normal in color. He has been lethargic recently and hiding a bit more. His appetite has also seemed to go down this morning. His poops are a bit watery, but they look relatively normal. His beard is grayish-black near the bottom(not fully black), but its always been like that since I have gotten him. Thank you in advance
