I think Logan gets confused. She's/they're here so why can't I be in.
Oh she/they left, I'll sit here where I saw them off and wait for their return.
If she came from a show home she may have been put away when the owners went out. If she came from a home where there were quite a few dogs she may have been selected to come into the house.
When my father had the Kelpies that's what he would do. When he would re-home an adult people would often say they were the best dog they'd ever had. Always following them around.
They did the same with my father, but they didn't always get a chance to do it. So when they did they stuck to him like glue.
For some of the oldies that became house yard dogs it would take them some time to settle into the idea that they could just hang around the back yard, some would even return to their run of a night because that's what they'd always done for the last 10 years why the sudden change.
