The Smooth Collie is a breed of dog developed originally for herding. It is a short-coated version of the Rough Collie of Lassie fame. The features of the head, particularly the 'sweet' expression, are considered very important in the show ring. The Smooth Collie is generally a sociable, easily trained family dog. Progressive retinal atrophy: Gradual degeneration of the retinas of the eyes, eventually leading to blindness. This disease is less common than CEA in Collies, but more difficult to breed away from, as symptoms are not usually detectable until the affected dog is middle-aged or older.
