Found: Juvenile book

I’m trying to remember the title of a children’s book that was probably written in the 1950s or earlier. It’s about a young woman who gets married and moves to the far north. She has a dog named Juno. Her family contracts whooping cough or something similar, but she’s the only one who survives. It may be based on a true story or nonfiction.

Mrs. Mike by Benedict & Nancy Freedman.
