I have a 10'x30' gravel dog run that my dogs stay in all day long. I trained them to only "potty" (1 and 2) in their dog run. It was very easy to do and only took about two weeks before they had it down pat. And this way I don't have to worry about land mines in the yard and dead spots in my grass. Teaching a dog to go on command is very useful, and seems to be very easy to teach them. I would suggest trying to teach her the "go potty" command, so she will go in the morning before you kennel her up for the day.
