Before I got my fence extended and Cowboy would jump out I would have to take Gracie out to find him. He and Gracie are best buds so I'd put her on a leash and walk down the road to where he was - he'd see her and come to her and I could get him. Any chance you could walk one of the other dogs in the direction you saw her go and possibly get her attention? Hopefully she just found a good hiding place and didn't just keep running... Grasping at straws here I know - but maybe, just maybe ...?
After a pretty much sleepless night I got up at daybreak and headed out again. I started down our road/driveway and there she was...headed AWAY from the barn and house. I called her, and after that long "LGD pause...should I or shouldn't I ?" she decided that she would come to me. So glad that she is home, and she was happy to see her breakfast. Now to fix the fence.
I forgot to mention that Mia got bit by a rattlesnake yesterday too. Her head is pretty swollen but she seems fine. It got her right on the tip of the nose, one little fang mark. I will be getting her some antibiotics.
