A Dog Is a Man's Best Friend

S6 E5: An early morning jogger finds the body of a young woman on a countryside trail, a purebred dog standing guard over her. Renoir's unit discovers the victim had an unusual hobby: agility competitions, the equivalent of horse jumping for canines. The woman and her dog were a winning duo. Candice joins the victim's kennel club with her beloved doggie Fun, who can't manage to do a single trick.
