Sounds as if she's doing fairly well considering you've only had her for a month.
How long is she left alone when you're at work?
My guys can 'hold it' all day, but of course they've been living in a home situation for a long time, but I personally don't like to leave them for more than 6 hours. They are not crated.
Do you practice 'alone training' at all?? Do a search and I'm sure you'll find lots of info.
Oh...and now we need to see some pictures!!!!
