For a while now I've been thinking about this christmas movie that I haven't seen a long time and it involves a family helping out santa's elves because one of them have trouble seeing. Its kind of like a sing-a-long christmas movie from late 80's-early 90's, what is the movie called?

What's the movie where there is a guy and a girl and they're looking for a older woman, possibly her mother, and the guy is a wolf. The guy/wolf buys her a ring and tries to make her fall in love with him.
