she is not outside for long periods of time. She is a border collie shephard. We bought her a sand box for her to dig in, but maybe it's not big enough. She can dig to the bottom and then maybe she's bored. There is a spot of dirt where there used to be a garden. I wonder if I put railroad ties, around that, then that could be her "sand box". If the land lord says it's oK. But I'm sure he wouldn't rather have her digging up the lawn. Thanks for the help and ideas.
