Freyja was pee pad trained last year when we got her and the winters are cold. This summer we have been taking her out to pee about every 4 hours and she has been doing great. However lately she has taken to pooping on our hall rug. I've been using Nature's Miracle spray and even shampooed the rug. When we went away she was even good about going outside.
Two problems:
1) We always have to take her out. She won't signal us that she needs to go. We tried jingle bells on the door, but they freaked her out. What next?
2) She always poops in my daughter and son-in-laws house and they do not have a sense of humor at all

In fact she is "banned" from their house.
Any suggestions would be appreciated.
