Like the title says, he's (I think) a campbell/indian runner mix who is walking around more horizontal than usual with a bloated lower belly. He looked fine yesterday. He almost looks like he's constipated, that's how he's walking around. He is a part of a pair, and usually he leads his lady around, but today he is kind of lagging behind, following behind her. Should I be concerned? Is this normal or could something be seriously wrong with him? Does anyone have any idea what this sounds like?
