Ruby might just be feeling a little anxious w/ you being away. When your hubby takes her out does he take her to her potty spot?
Maybe now that you will be away from home more a play pen / den of larger size might work? I believe there a few members here who use them and seem real happy with them.
They have an area to sleep, play, potty, eat/drink, etc. Room to roam sorda speak...This way they don't feel so confined in a crate for hours on end.
If not, maybe you can confine her to a easy to clean room like a laundry or service porch area?
Just a thought...
