Here's the Valentine Sweethearts line-up:  apricots (girl, boy, girl), tricolor silver merles (officially called blue merles; both girls), dark red merles (boy, girl, boy), and tricolor blacks (both boys).  They each have white on their chests.  My photography does not do them justice at all!  Each is absolutely stunning.  Names to follow soon... our grandkids have the honor of naming our pups.  :))
