Call her GO for short and it will be nice. She will answer to that.
We have an airedale that was almost two when we rescued him. He had been a lost dog and we have no idea what his original name was. The foster home he was in for a few weeks called him Andy. My husband didn't like that so we changed his name to MacDuff. Within a week he started answering to his new name. Now he answers to that as well as Duff and Duffy.
I also call him and my other rescue airedale, Sadie, by silly things like McDoodlebopper and others. They know when they are being called.
