This conclusion came because she weighted only 14 pounds while as a German Shepherd mix that she is, normally should weigh around 75 pounds. But apparently she surprised them all and turned out to be much more stronger that they ever imagined. After surviving the first night, the first few days were indeed very delicate as she was still so fragile.
When she was found she had no strength on her whats so ever. Although she is recovering well and gaining some weight, still is to weak to play or do normal activity. But what she does enjoy is just laying on the grass outside and playing with her new toys.
