Sitter Needed For 1 Dog In Waukesha

I am looking for someone who could stay overnight in our home with our dog while we are at a family reunion out of state. She is a rescue and was abused in her youth, so she can be pretty anxious. For that reason, she doesn't do very well with stays outside of our home. She doesn't need to be walked -- she can just go outside and run in our yard (big lot, electric fence). She is quite predictable and has a solid routine. We have someone who usually stays with her when we're gone, but she has a conflict with these dates.
