New to GSD.
This is my first GSD. Rescued her from an older couple who wanted to use her for search and rescue. After the husband health took a turn for the worse they decide to let her go. She was originally $800. But after going to pick her up the husband couldn't bring himself to charging me. She was well behaved when we got there. Since getting her home the last 3 days have been a bit frustrating. She doesn't seem to listen as well. I'm hoping this is a separation anxiety issue and she will soon get over it. Any advice would be greatly appreciated.
