We have an invisible fence so she goes out by herself now. She eats anything outside. Twigs, dirt, acorns, more dirt, etc. Thank god she has enough sense not to eat poop. She isn't particularly destructive in the house, but did eat a portion of our carpeted mat that we keep by the back door. Lots of red carpet in her poop the next day. I use the command "leave it" which only seems to work in the house. I've tried a spray bottle to stop her outside but she sort of seems to like it in a fiendish way.
