Rudolph Valentino and his dog. Actor and heart-throb Valentino appeared in many films, including Moran of the Lady Letty (1921), which was filmed in a variety of Southern California locations, including Balboa, Anaheim Landing, Catalina, and the Lasky Camp in Santa Ana Canyon. Does anyone know what his dog was called?
