I knew she'd be at it again! She did this her last heat cycle before, when she wasn't pregnant but her breasts/nipples had grown a little. Now, she's 1 month into pregnancy starting to show and her nipples/breasts are growing and she's constantly scratching, I say No and she will stop temporarily, but she's doing it awhile it's sleepy time and everyone is asleep. Today is the first day I noticed she had scratched until it was bleeding a little.. Now I need some suggestions.. What can I use to help her that is safe for her and the unborn pups? Last time I used aveeno lotion and rubbed it on her 2-3x a day. I'm not sure if I need something unscented natural etc...

Thanks in advanced.
