It’s a dog-eat-dog world. Literally, in fact, at New Ground Theatre’s production of playwright Micah Schraft's A Dog’s House, when Jock – the dog of Michael (Kyle Taylor) and Eden (Tabitha Oles) – kills the dog new neighbors Robert (Jordan L. Smith) and Nicole (Ashley Hoskins). As Michael and Eden struggle with the moral implications of what to do next, they find out a lot about themselves and their relationship, and Friday's opening-night performance of director Jacque Cohoon’s production was an intimate, emotional experience I wasn’t expecting.
