 When Sgt. Quincannon (Victor McLaglen (qv)) is addressing the  troops and warning them to "watch them words," he asks who owns a  dog, without receiving an answer. He concludes, "Nice dog! Irish  setter!" The scene was improvised on the spot by director  John Ford (I) (qv). The dog was an unnamed Navajo pet that had  fallen asleep during the setup. Multiple takes were required because  McLaglen kept blowing the line, calling the dog a "cocker spaniel."
