Honeymoon

Honeymoon (1928) is a comedy directed by Robert A. Golden rated 9.0/10.

Two men are rivals for the same girl. When she finally agrees to marry one, the other--appearing to be magnanimous in defeat--presents his former rival with a beautiful German Shepherd dog as a wedding present. It turns out, however, that he had an ulterior motive--he had trained the pooch to allow absolutely no one to get near the young woman. Complications ensue.
