Thanks guys.
That makes me feel better. I was getting a little stressed. He's 9 months and 4 pounds so I think the dehydration would come pretty easily with his sickness. He did much better last night! Didn't get sick one time. I was trying to get him to sleep in his pen next to my bed, but he wanted out and up on the bed with me. I think I'm just going to let the little guy sleep with me.
They did keep him in a crate 23 hours a day.
He's a little mangy because he's never been groomed before (but he will be as soon as his stress levels decrease!_
