You're trying to control the 'mess' right? The same thing happened to our dogs before they got spayed. We had confined them to the kitchen when we were gone, and put old sheets over their beds and where they lie down a lot (like the couch). If you have a crate that would be good for when you're away or sleeping and can't watch her. Oh, and watch her carefully when you take her out - male dogs will come from all over! Good luck.
