Because of 2 surgeries, I can't go back to walking Logan yet, so we installed a fence. She has plenty of room to run and chase critters and play. We think she's part terrier of some kind (as well as a herding GSD) because I have holes to China in my yard. I try to stay out with her and play so she's not bored, she just is keen on tracking underground critters like moles, groundhogs etc. I try to wash her feetsies before I bring her in on muddy days. She'll only stop when I threaten "The CAN" (soda can filled with coins).
