You know that you're an angel for taking and providing for this sweet dog. Dogs do get traumitized just like people. We saw someone in a car "dump" a little black poodle and drive off. Being dog lovers like you, we just had to pick her up. She had a rough time learning to trust and at first didn't even want to go outside by herself. Even so, she became a loving, loyal, devoted pet and I miss her to this day. (she was very old, too)---can't imagine why someone would dump a dog???
