What's the Name of That Book??? discussion

A woman I know in her 70's asked me to help with this recently. Any ideas? These are her words...

My mom used to quote me a book or poem about a little pig that “Wasn’t cross or mean. The only trouble with her was she just would not keep clean.” I can’t remember the pig’s name, and it’s really bothering me. I know it’s a long shot, but does anyone else remember it?

Elizabeth, around what year was this book read?

https://www.goodreads.com/book/show/1... could it be from Perfect Pigs: an introduction to manners? I loved that book as a kid!

Probably in the 50's-60's.
