“She had a trained German Shepherd that circled around her as she walked”
You know, that dog may not have been actually “trained.”
A bright German Shepherd is a wonder to behold. All I ever had to do was to make mine understand what I wanted her to do, and she would do it.
Through the years I had her, she only barked on four occasions, and every time it was called for.
There’s a special type of traing for Shepherds. Can’t remeber what it’s called.
