Lynn, I agree with the others. I had never used any kind of crate before but when Nick was born 2 years ago we decided to try it with Mr. Magoo (shitzu) just to be safe when he was a toddler. Mr. Magoo now loves to go in his little house. It is all his to have when he wants peace and quiet. I think this will be the easiest way to potty train Snow White. Once she's trained, you may or may not want to continue to use the crate...probably will until she's over the "chewing stage" when she's home alone. The most important thing in any puppy training is Praise Praise Praise!
