When i got lil mama out for her meet and greet with her sister, she was extremely apprehensive, and only began to move when her sister started to walk ahead of her. But once i opened the outside door her demeanor changed entirely. Outside she became way more active and playful, and when i opened the gate to the yard she ran inside. Lil mama and her sister started to run around and into each other. Eventually another dog walked pass them she showed little interest and continued to run around. Towards the end she maintained her high energy.
