Farms have to have a couple of dogs.
When she was a puppy, Moe showed up with her sisters, Larry and Curly, and her mom Molly. They were dumped in the country and left to fend for themselves. Bad people!! Luckily for them they found their way to my parent's farm where they had it easy. Her sisters and Mom have all gone to the Rainbow Bridge, but she has Shadow to keep her company.
Shadow was another "free" dog who just showed up.
