Thank you everyone for your prayers.

You guys are terrific.
I went to pick up Charlie today. They ran every test they could do and could not find anything.

Which depending on how you look at it, is good news
Dr. Bing thinks he may have picked up some kind of parasite that made him sick. He is on a certain kind of canned dog food (which Im not happy about it bc I dont like canned) but its suppose to help him gain weight. But he only gets 1/4 cup twice a day. WOW! Shock for him bc he is free fed. Poor thing.
It could just be that he is just getting older. I hate that tho. He is home now and went straight to his crate.
Thank you again for all your prayers. You guys are terrific!
