Chance's coat sure does look shiny, for him to be sick. The thought about him being constipated, could make him feel bad I suppose. Sure doesn't make humans feel too well does it?

I hope he gets to feeling well really quick, it is awful to be at home alone, with a sick baby. You do what you can to feel better yourself, if that means calling a vet at home or whatever and like I said before ask lots of questions.
