Great story.
A year ago, had an Australian shepherd peek in the front window at New Years night. She's and older dog about 11+ years of age. She was pretty over weight so I figured she was well loved and missing from her home. After weeks of putting up fliers and contacting every shelter, vet, groomer, etc I could think of,it seems like a clear case of abandonment. Maybe the owner died and In laws let her free? Who knows. Long story short, she got amazingly well in minutes with my dogs. After a couple months of searching for the owners we said screw it and are keeping her. We put her on a diet and in about a years time she lost 30 pounds. Yes, she was built like a keg - lol.
She changed a lot of things here in the house and tries to bring order. She's had her work cut out for her but she's such a neat dog. She can keep 3 Rottweilers in line no problem. She follows me all over the yard and is like a shadow.
