Looking for some help and I haven't seen this brought up before... Lilly has a bad habit of pulling up the landscaping tarp (from underneath the rocks). Now that Spring is here the backyard looks awful and we need some ideas on how to stop this. The backyard is fenced in, so most days the doggies are out there when we are at work. They have toys, water and dog houses to go in. Brody never did this, so we're pretty sure it's her. Any ideas would be really appreciated.
